Eos 70d

I have a new 70d and have found that when using the live view screen you cannot adjust the shutter speed below 1/30 sec using the touch screen.
The screen will also only show the shutter simulation if its set above this 1/30, anything below and the screen is too dark to see.
This seems a bit odd as i know my mates eos 6d does allow it.
Any ideas

I have the 70D also and in live view using touch screen, I can go pretty much the whole range of shutter speeds. From 30 seconds to just about 1/8000 of a second and thats when it gets dark. At 1/30 of a second there is plenty of light..

I am unable to download my picture from my camera canon eos 70d to my computer.

I AM UNABLE TO DOWNLOAD MY PICTURE FROM CAMERA CANON EOS 70D TO MY COMPUTER. I HAVE INSTALL THE SOFTWARE FROM CANON EOS SOLUTION DISK 28.2.

"...The question then came up whether repeated removal/insertion of the card (in the computer and camera) might eventually wear out the contacts on the card, or worse the camera..."
Yes, there will be wear and tear over time. It also is possible to force a card into the slot crooked and damage the socket.
Are these much of an issue?
In my opinion, no. I change memory cards fairly frequently (mostly Compact Flash, which are probably the most easily damaged), sometimes use 12 or 15 memory cards in a day's shoot and have been doing that shooting digitally for ten years... And have never had even one card wear out or managed to damage a card or socket myself.
Note: I have pulled a card out too quickly, while it was still writing, and lost about 1/3 of the images on the card... Once! I also have had one "bad card" right from new, from a major manufacturer. Three other identical cards are working fine.
I do have one older DSLR with a "bent pin" in the Compact Flash socket.... But I bought it that way for $15 in hopes of fixing it. Unfortunately I think the particular pin that got bent managed to short out some of the other electronics in the camera, so it's probably not practical to fix (makes a nice paperweight). I've seen other cameras, particularly those using Compact Flash memory, with bent pins. Some were pretty easily fixed. Others needed a new socket or more.
Just looking at the posts on various discussion forums, I suspect it's a much more frequent issue for the USB cable or the USB socket in the camera to wear or get damaged. Plus camera batteries are only good for a certain number of charge/discharge cycles (I've heard 400X is typical, but don't really know).
So personally I'd be more concerned about directly linking the camera with the USB cable and leaving the camera powered on while downloading.... Feel better just pulling the memory card and using a card reader.

You could try using the DNG converter 8.7 on Windows vista:

Lightroom 5.2 vs. Canon EOS 70D RAW

Hello,
I am testing the trial version of Lightroom 5.2. My new camera is a Canon EOS 70D. When importing RAW files into Lightroom the colors of some photos are wrong. RAWs from my older 450D are fine.
For example on one photo the sky isn't blue but turquoise. When using the DNG Converter I get the same color. The sky was blue though. When opening the file in Digital Photo Professional by Canon, the sky is blue as it should be.
It happens on some other photos as well. Mostly if they have a high blue content. If in Lightroom I increase the blue content and decrease the shades it almost looks as it should.
The question now is: am I doing something wrong, do I need an update or additional plugins or is Lightroom simply interpreting the RAW wrong and will it be solved soon?
Cheers,
Sheepy

I managed to calibrate my monitors with a friend's hardware calibrator. The display of the photo in LR didn't change much. Still way too greenish sky.
Now I noticed that depending on the export option in LR (sRGB, aRGB, ProPhoto) I get pretty different colors in the exported JPEG files if I view them in IrfanView. None of them looks like the original that I see in LR. Funnily I noticed when writing this post that all exported images in the browser look the same - as each other and as in LR. looking at the LR-exports in LR they look the same - greenish sky. Looking at the LR-exports in DPP they look the same - blue sky. I managed to set IrfanView to enable color management with current monitor profile. Now I get the same view in LR, Irfanview and Firefox. I guess that's a plus. Furthermore I found an option in DPP to use the monitor profile - the sky looks a litlle green but there are differences to LR still.
LR sRGB
LR aRGB
LR ProPhoto
DPP aRGB with color management
Now that I managed to get the photos to look (almost) the same in all the applications that I use (FF, LR, IV being the most important) and having the monitors calibrated I can go back to my original question.
How comes that the sky looks so green although it wasn't when I shot the photo? Are there any more settings that I can make to get the colors on import better? Can I simply and with good conscience move my sliders now so that the image looks the way I like it and others will see it the same way (mainly on a website)?
Edit: Actually they only look green when writing the post. When looking at the finished post they look blue to me. Which is not what I saw in all my programs before. I am a little lost with how colors work I guess. I'd appreciate any hints.
Edit 2: When clicking on the images in this post they have the original color.

LCD live viewing & copy work with EOS 70D (W)

Hi,
Can anyone please provide insight, guidance, solutions to accomplish this efficiently?
Goal/operation:
I want to use the camera for copy work: portfolio, flat art, photos, objects etc. I have old family photo albums I want to copy/photograph each image separately without removing/disturbing/damaging the images in the books.
The camera is mounted on a vertical copy stand shooting down (subject is mainly flat art).
I want to be able to view through the LCD in live view (camera is 90º facing down at copy board), have manual control, set up & align the subject and shoot the photos using the flash lighting system in quick efficient production process.
Equipment used:
Camera EOS 70D (W)
Minolta Copy stand
Novatron 240 portable light system, 2 lights with polarized sheet film
synch connections:
wireless - Pocket Wizard Plus 2 Transceiver.
wired - Nikon AS-15 Hot shot cord adapter
PROBLEM
I am having issues being able to view through the LCD, set up & align the subject and shoot the photos - without jumping through hoops.
It seems I have to switch to Av from M after shutter release to view subject in LCD, then switch back to M for the next shot, camera fails to shoot and shows error message: “Press start/stop button to activate movie shooting”. This doesn’t make sense as I’m not movie shooting.
If I change the mode to “Flash off” and back to “M” then it appears to work, however once I switch to Av mode to view the subject again, it starts the process all over.
There must be a better/easier way.
Could this be a potential bug in the camera? or am I missing something? I don’t see solutions in manual.
Will mode setting “C” Custom allow “Live viewing” w/ custom “Manual control” to bypass the need to use “M” manual setting that wont allow LCD viewing?
Camera settings:
Shooting with LCD (live view shooting)
mode setting:
Av - for live viewing and setup of subject
Then switch to M - Manual for manual control and shutter release
Also - I would like to connect to Apple Mac Laptop computer, live view on screen, and if possible have the option to record the photos direct to computer hard disk. Can this be done with this camera? IF so, what is needed?
Best regards,
J

-Canon 70D have built-in Wifi, so you can connect your camera with your computer wirelessly for tethered shooting. I have PC so the instruction may be different, but you need to install Canon EOS Utility.
-You can do everything in M mode even Live View. I think you are doing something wrong here, you may need to re-read your manual regarding this problem.
-C mode is customized M mode, so you can do everything in C mode also. With C mode, you can save all the setting so you can come back later. It's a great use in your case where you can make your C mode has all the settings for your work, then when you take the camera out to shoot something else, use other mode. Later, when you come back, just switch back to C so you don't have to change anything.

Raw conversion: open EOS 70D Raw files in Elements 8?

I have a Windows 7 operating system, and Photoshop Elements 8. I have a new Canon EOS 70D and want to find
an adobe Raw converter which will allow appropriate processing, and connecting finished results to Elements 8 for conversion to routine JPeg or PSD? Any reccomendations?

The EOS 70D was first supported in Adobe Camera Raw (ACR) 8.2
http://helpx.adobe.com/creative-suite/kb/camera-raw-plug-supported-cameras.html
ACR8.2 is only compatible with Elements 11 and 12. Not Elements 8 so you cannot open Raw files from the 70D in Elements 8.
Your choices:
Upgrade to Elements 12, OR
Download the free Adobe DNG converter and convert all 70D Raw files to DNGs. That adds an extra step to your workflow each time you shoot more pictures. Then edit the DNGs in Elements 8.

Importing *.CR2 files to Lightroom 3.6 - support of Canon EOS 70D

Hi,
try to import *.CR2 files from my new camera Canon EOS 70D to Lightroom 3.6, but it is not supporting format. What to do? Can anyone help me. Thanks a lot for your answers, yours Petr.

The DNG files are mainly supported by Adobe software. The CR2 files would be for any software that knows how to deal with 70D raw files and so the right answer for you depends on whether you feel you’ll want to use the raw data in other software or not, and what you feel you want decades from now if Adobe or Canon no longer exist. Personally, I’d just upgrade to LR 5.2 and not worry about DNGs, but I also already have compatible hardware so am not hit by having to upgrade my OS or hardware.

Photoshop Elements 10 - Camera Raw für EOS 70D

Hallo, hat von Euch jemand eine Ahnung wie ich bei Photoshop Elements 10 Fotos im Raw-Format von einer Canon EOS 70D öffnen kann. Habe erst heute aktualisiert Camera raw, aber ich kann die Fotos trotzdem nicht öffnen. Vielen Dank für Eure Hilfe - lbg Christine

Adobe updates Camera Raw to support new cameras only for the latest (at the time) version of Photoshop.

http://forums.adobe.com/thread/311515?tstart=0
Specifically, if Photoshop Elements 10 cannot update to Camera Raw 8.2 or newer, which I suspect it can't, then you will need to do one of two things:
1. For the greatest integration and convenience, upgrade to the latest version of Photoshop Elements (currently 12). Then you will be able to open your 70D files directly.
2. Download and install the latest version of the free DNG Converter. Then you will be able to convert your 70D .CR2 raw files to .DNG format, that Photoshop Elements 10 will be able to open.

EOS-70D Announcement and Preview

London, UK, 2 July 2013 – Canon today unveils an outstanding new addition to its world-famous EOS series – the EOS 70D. Designed for aspiring enthusiast photographers, the EOS 70D is the ideal camera for anyone looking to take their photography to the next level. It combines completely new, world-first Canon imaging technology with powerful, creative and wireless sharing features – delivering a responsive, all-purpose camera ideal for capturing the moment with stunning images and Full HD video.
Capture the moment with stills and Full HD movies
The EOS 70D features a new 20.2 MP APS-C CMOS sensor, designed and manufactured by Canon. It’s the first Digital SLR in the world to feature ground-breaking Dual Pixel CMOS AF technology, which delivers smooth and accurate autofocus (AF) when shooting Full HD movies and fast AF acquisition when shooting in Live View mode. Paired with the 14-bit DIGIC 5+ processor and 19-point all cross-type AF System, the EOS 70D captures incredible, full resolution images at up to 7 frames per second, with up to 65 JPEG or 16 RAW images in a single burst*. Additionally, a native ISO range of ISO 100-12800 enables photographers to shoot in lower light conditions and use faster shutter speeds whilst retaining high image quality.
“I was incredibly impressed with how many new technologies the EOS 70D packs into one body, and how versatile it is,” said Brutus Östling, Canon Ambassador. “The EOS 70D is the perfect camera for anyone that wants to develop their photography skills. Not only is it suited to shooting people, landscapes and action easily and in outstanding quality, but also filming subjects in Full HD with focus speeds I never thought would be possible. The camera proved itself in the most challenging of circumstances, and had a range of new-generation technologies to comfortably solve any test I threw at it – especially with the new Dual Pixel CMOS AF technology. It really takes DSLR shooting and filmmaking to a whole new level.”
Canon’s new Dual Pixel CMOS AF provides swift AF performance when shooting in Live View mode and smooth accurate focus for Full HD movies. It makes it easy for users to take their next step with movies, enabling them to keep moving subjects in sharp focus and create professional-looking pull-focus effects. The technology utilises advanced CMOS architecture, allowing two photodiodes to be mounted within each pixel, both of which can be read independently to achieve autofocus, or together for image capture, with maximum image quality at all times.
An advanced AF system for stills includes 19 cross-type AF points spread across the frame, providing high speed, accurate AF – ideal for tracking sports and wildlife subjects as they move within the frame. The AF system is customisable, allowing photographers to adapt to the subject they’re shooting. AF points can be used individually, together in small groups, or as a wide active area for more unpredictable subjects. A dedicated AF area selection button, positioned conveniently next to the shutter release, enables quick switching between modes, without having to take the camera away from the eye.
Expertly designed for professional control
The EOS 70D’s powerful specification is packed into an expertly-engineered body that’s designed for comfort and swift operation. The Intelligent Viewfinder, with 98 per cent frame coverage and 0.95x magnification, allows photographers to comfortably frame their images and visualise settings via the electronic overlay. Conveniently-placed controls provide instant access to the most frequently used settings, such as ISO, AF mode selection and metering, so users can quickly change settings and concentrate on capturing the moment.
A 7.7cm (3.0”) Vari-angle Clear View LCD II Touch screen with a sharp 1,040k dot resolution is ideal for video shooting, or composing images from unusual and creative angles. The screen is a capacitive type, which supports a series of multi-touch gestures including swiping and pinch-zooming – perfect for navigating menus, amending settings or flicking through images.
Clever connectivity for easy control and instant sharing
The EOS 70D is the latest EOS model to feature integrated Wi-Fi, providing the freedom to remotely control the camera, as well as share images. Using Wi-Fi connectivity, users can connect to the EOS Remote app and control a wide range of image settings, including ISO and exposure, as well as focus and release the shutter. Photographers can also remotely use Live View mode, as well as review and rate their images.
Instant creativity unleashed
The EOS 70D features a host of creative modes to make capturing unique images easy. In-camera HDR removes the challenges of shooting in tricky, high contrast situations, merging three exposures into one that captures more detail in both the shadow and highlight areas. With multiple-exposure mode, photographers can shoot and combine up to nine exposures into a single image, or use a range of Creative Filters to instantly change the style and look of their shot.
Experimenting with creative off-camera flash is easy, thanks to the Integrated Speedlite transmitter, which provides in-camera control of multiple Canon Speedlite EX flash units.
Creative Full HD Movies
Alongside beautiful stills, the EOS 70D allows photographers to create high quality movies with ease. Full HD (1920 x 1080p) resolution video can be captured with a choice of selectable frame rates, including 30, 25 or 24fps, and 60 and 50fps at 720p, and a range of compression options for post-editing and sharing. Thanks to new Dual Pixel CMOS AF, Movie Servo AF mode tracks subjects as they move, or even as shots are recomposed, ensuring they’re always in focus. Alternatively, users can select different focus areas over 80 per cent of the frame** simply by tapping the touch-screen, even when recording – ensuring that movies stay sharp and clear if a subject moves or the user changes the composition of a shot.
Videographers can also enjoy stereo sound using the internal microphone, or enhance audio with the in-built external microphone input terminal. Full control over settings such as aperture and ISO is also possible within manual mode, giving users greater freedom as their skills develop.

Wann wird Adobe Camera RAW 6.7 die Canon EOS 70D unterstützen?

Wie Mylenium schon geschrieben hat wird CameraRAW 6.7 die 70D nicht unterstützen.
Um weitere Ratschläge zu geben fehlen Infos welche Adobe-Versionen du einsetzt. Eigentlich erfolgt das Update von CameraRaw auf neuere Versionen automatisch. Wenn deine Version allerdiings schon etwas sehr alt ist, wirst du um eine kostenpflichtiges Update deiner Software nicht umhin kommen.
Eine Alternative wäre allerdings die Konvertierung deiner RAW-Dateien ins dng-Format.

How open raw from canon eos 70D in elements 11

I cannot open raw from canon eos 70D in photoshop elements 11. Help me please.

Your PSE is too old—the camera was released after a newer version of software was available and Adobe only adds new camera support to the newest version of software.
Specifically, the 7D Mark II needs ACR 8.7 and PSE12 can only be updated to ACR 8.5.
Your choices are to:
Use the DNG Converter 8.7 or newer to create DNGs from the CR2s and those DNGs will open in the older version of ACR that comes with PSE12, OR
Buy the newer version of Element 13 that can be updated to a new enough Adobe Camera Raw plugin.
The DNG Converter is available from the Adobe Updates page:
http://www.adobe.com/downloads/updates
And the newer version of Elements is available from the Adobe Products page:
http://www.adobe.com/products/catalog/software.html
Another option would be to use Lightroom 5.7 or newer and use Edit in Photoshop Elements from LR once most of your raw adjustments are done, for any final touches in Elements.
For any of these choices you’d want to download the latest updates and run the software in trial mode to make sure your computer is compatible before paying anything.
BTW, I have the 7D Mark II and like it very much, having upgraded from an older Digital Rebel, but I’m not that thrilled with the in-camera JPG processing so always use Adobe products for raw development.

EOS 70D - Mode Dial problem...

Hi ... I'm Patricio from Argentina.
One week ago I received from the U.S. a Canon EOS 70D.
It worked ok until yesterday.
Since today, when I want to choose different modes with the dial mode, the camera just sets: P or A+ (auto).
- If I select A+ mode (Auto mode) or "Disabling Flash mode" or "Manual mode" .... the camera sets as A+ (Auto mode).
- If I select modes: CA, SCN, C, B, AV, TV, or P ... the camera sets as "P mode".
I have read some similar cases in other models of EOS cameras ... they recommen do a "hard reset" by removing the main battery and clock battery.
I tried to do that, but this model (EOS 70D) seems to have a battery for the date and clock ... but it is internal, It`s a rechargeable battery.
I guess as a new model, there is no more than the actual firmware, that comes from factory ... so I can`t try to update, since there is no other firmware available.
Anyone have any suggestions before taking it for service?
Thanks!
you can see what's wrong with my 70D here: (the mode selected by the dial, it's not the same on the screen)

Have you tried powering off the camera, removing the battery, waiting a minute, re-inserting the battery, and powering it back on?
The on/off switch is really puts the camera into an extended power-saving sleep mode. The camera still technically has power. When you turn on the camera again, the camera really just wakes up -- it does NOT actually re-start or reload the firmware.
If, however, you remove the batteries from the camera, you (mostly) deprive it of power. When you insert the battery and power it up it actually forces the camera to load the stored firmware again... you are in effect "rebooting" the camera when you do this -- the camera does not "reboot" simply by turning the power swtich off and on again.
I did say "mostly" deprive power when you remove the battery because there is a technicality. Depending on the camera body, most cameras have a 2nd battery used to store settings and also maintiain the date/time clock. That battery is either a removable coin size battery OR it's a built-in rechrageable battery which recharges off the regular battery. If you store the camera without a battery for too long, it will prompt you for the date & time when it powers up -- but this means the internal battery was depleted of power.
I *think* your 70D has an internal rechargeable battery. Simply leaving the batteries out over-night will not be enough. Hopefully just re-started the firmware by ejecting and re-inserting the main battery will be enough to fix the problem.

EOS 70D display screen not working because of humidity - Canon cutomer service totally unhelpful

Hi!
I have purchased an EOS 70D last October. Everything was working perfectly until I took it to the Caribbean, where on the second day the display screen stopped working. I could still take photos, but nothing was shown on the screen. I currently live in Canada. I took the camera to the store, where they told me that I have to send the camera (that still has warranty on it) at my own cost to the official repair centre. After a week, i got a letter from them, saying the following:
"We have received your equipment for evaluation and repair. Upon further examination it was determined that we are unable to repair your equipment therefore
Canon has suggested a replacement product to you in exchange for your original unit at the cost detailed below. Please respond to this estimate promptly to
avoid having your equipment returned.
We will replace your equipment with a EOS 70D. The new serial number is not yet available.
Upon inspection, technician found unit is beyond repair due to moisture damage. Estimate has been adjusted to reflect replacement suggestion."
I am furious. They are offering me to buy a new camera for the same price. I called customer service and asked them to explain the letter. They said they will send me photos of the inside of the camera, where they have found mositure. I asked them to re-check it, as I didn't misuse it, I didn't drop it in the water, or anything of that kind. They said the camera must have been used in a very humid/or very cold place. Can they be serious? Is that really my fault? I mean, I bought the camera to be able to take pictures anywhere I go. I didn't do anything extra to it or with it. I will take this as far as I can, I just don't find this a normal response. Any suggestions??? Anyone had the same problem before?

Every post ought to have a learning opportunity so I am attaching a list compiled by a Canon technical advisor addressing the problem of handling photographic equipment in hot weather.
Hot Weather Photo Equipment Handling Tips
Compiled by Chuck Westfall, Technical Advisor/Canon U.S.A., Inc.
1.) Avoid Condensation:
This is a biggie. If temperature and humidity differentials are high enough, condensation may occur when moving photo equipment from a relatively cool environment such as an air-conditioned vehicle, to a warmer one. When condensation forms inside a lens, for instance, internal elements can fog up, preventing clear images. When condensation gets bad enough inside a camera body, it can cause short circuits resulting in unexpected shutdowns. Worse yet, when equipment temperatures finally equalize to the warmer environment, water droplets on glass surfaces inside a lens may dry out and leave spots, mildew or fungus that can’t be cleaned by the photographer.
Similarly, when condensation dries up inside a camera, fungus, mildew, rust or corrosion may be left behind on printed circuit boards, viewfinder eyepieces, shutter curtains, or other internal components. If any of this happens, the equipment may be permanently damaged.
Incidentally, no matter how good it is, ‘weather sealing’ cannot prevent condensation, nor was it ever intended to do so. Damage caused by condensation is considered a user error, and it will void warranty coverage. One of the best methods to avoid condensation is to allow photo equipment to warm up gradually before exposing it to a hot environment. If this is not practical, consider placing the equipment in an airtight, resealable plastic bag with silica gel packets inside before exposing it to heat. (Don’t forget to squeeze as much air as possible out of the bag before you seal it, otherwise this technique may not work.) Using this method, the condensation will form on the bag instead of the equipment. Once the condensation on the bag has dried out, it should be safe to remove the equipment and start using it.
On a related matter, in hot and humid conditions, perspiration may cause condensation to form on your camera’s viewfinder eyepiece. Some camera manufacturers including Canon offer anti-fog eyepieces to prevent condensation from forming.
2.) What To Do When Condensation Has Occurred:
Use a soft, dry clean cloth to remove moisture from exterior surfaces. If possible, place the equipment in a dry, well-ventilated area to prevent further condensation from occurring.
3.) Cover Equipment When Not In Use:
If you must leave your camera equipment exposed to high heat and/or humidity conditions for long periods of time, consider covering it with a dry white towel when it’s not in use. Even when condensation is not an issue, heat absorption is another big concern for professional cameras and lenses, and especially digital SLRs. Cameras are designed to operate within a specific range of temperature and humidity conditions. For instance, the EOS-1D Mark IV professional camera has a high-end temperature rating of 45C/113F and a humidity rating of 85% or less. Since most camera bodies are black, internal temperatures can exceed this limit even when the ambient temperature is below it.
4.) Avoid or Limit the Use of Camera Settings that Generate Heat:
Heat build-up caused by ambient temperatures is one problem, but the other side of the coin is heat build-up caused by the camera itself. This has become more of an issue recently with professional digital SLRs due to the incorporation of new features such as Live View and HD video recording. These features generate heat from several camera components including battery packs, image sensors and LCD screens. If you plan on using Live View or recording video outdoors in high-temperature environments with your digital SLR, there are a couple of things you can do to minimize heat build-up inside the camera:
Limit the use of Live View for still shots. This will minimize heat build-up from the image sensor and LCD screen.
Use an external monitor when recording video. This will shut off the camera’s LCD screen.
Use an AC Adapter Kit. This will reduce heat build-up by eliminating battery packs.
Set the camera’s Auto Power Off setting to a reasonably short interval. Let the camera help to minimize heat build-up by allowing it to shut down automatically after a minute or two of inactivity. This will also conserve battery power.
5.) Storing Equipment in Hot Weather:
In high temperature environments with ambient humidity over 80%, use silica gel packets in your gadget bag or equipment case to absorb excessive moisture and protect your camera gear. Silica gel packets can be purchased in quantity from professional camera dealers and chemical supply houses, and are available in clear or moisture-indicating varieties. For long-term storage, consider storing camera equipment in Tupperware or similar sealable plastic containers with silica gel packets to absorb moisture and prevent fungus and mildew. In severely humid environments, even silica gel packets may be insufficient; so-called “camera dry cabinets” from manufacturers such as Toyo Living are available for such conditions. No matter what kind of storage container you use, ideally the humidity level should be less than 60% for maximum protection. Relatively inexpensive hygrometers of the type used for cigar thermidors are available to monitor humidity levels inside the containers. Remember to test hygrometers at least once a year, and recalibrate them if necessary.
6.) Store Battery Packs Separately and Keep Equipment Clean:
To prevent corrosion of your camera’s electrical contacts, remove battery packs prior to long-term storage. Also, as a matter of good housekeeping, clean cameras and lenses regularly and thoroughly. This is especially important in hot and humid weather, or after your camera equipment has been exposed to rain or condensation, to prevent mildew and fungus from forming.
