5D Mark III problems

Just got my new camera and couldn't figger out how to get manual exposures to work, so I used auto settings until I had time to read the manual thouroughly. Having done that, I did not find a solution to the problem. When I'm on manual, it seems that the mirror sticks up... all of the auto settings are working fine, though, so it's not a mechanical problem. This happens with a large variety of lenses that I use with my D60.
Another problem is that I prefer to shoot RAW but it occasionally reverts to JPG without me consciously changing it. This is just strange.

I know 2 ways that can toggle between JPG and RAW: Press Q / then INFO. and the SET button (if the shortcut has been turned on). I think in your case, the SET button may get pressed when you put your camera down and you accidentally rotate the dial. You can try to remove this option from the SET button via custom function. Just my guess.

Canon 5D Mark III Raw Files Not Viewable in Finder for Snow Leopard 10.6.8

System specs:
Computer: Mid 2008 Mac Pro - Dual Quad Core
OS: OS X 10.6.8 (includes the most recent Digital Camera Raw Updates)
Camera: Canon 5D Mark III
Problem:
Finder can not preview the thumbnails from this camera. While not that big of a deal (I can use Lightroom, Bridge, etc to view these) it is a bit of an annoyance when transfering files around from one volume to another.
According to this Apple support page - http://support.apple.com/kb/HT3825?viewlocale=en_US&locale=en_US - I may need to update iPhoto, in order for the Digital Camera Raw Updates to work (specifically 3.12 from last year that addressd the 5D3's raw files).
As a pro photographer, I have ZERO use for iPhoto. But, I would be willing to spend the $15 for the newest version of iPhoto, if I knew that would solve the Finder thumbnail problem.
I would love a definitive answer, without having to call Apple and paying the "per-incident support fee."

I manually installed the latest RAW update (3.13 I think - for 10.6.8) .... worked for me.
(auto-update didn't do **** about raw update)
now aperture and os-x (10.6.8) show the 5dmk3 raw's.

RAW Processing problems with Canon 5D Mark iii

I am having problems with the RAW files coming from my new 5D Mark iii in Aperture. I have the latest version of Aperture (and update) installed. Selecting a picture style on the 5D doesn't seem to yield any results because when I import the photo into aperture all the images go very dark. I have to pull the exposure levels up all the way to get a decent exposure. The histogram on my camera looks perfect but when imported into Aperutre the histogram changes. I have my custom picture style set to give me a very flat image (contrast off, sharpening off, saturation -2, color tone 0). The images looks very flat and perfect in my LCD but once imported into aperture the RAW processing makes it very dark. I even tried shooting the exact photo in three completely different picture styles but they all look identical once they are in aperture. What's going on??

Here is a side by side comparison of a RAW image in the latest versions of Aperture and Lightroom. I have never had these issues with the 5D Mark II only the Mark III. As you can see Lightroom produces a nice flat image while Aperture is under-exposing the image. Any thoughts? I really want to continue to use Aperture but with my recent camera upgrade to the Mark III I don't see how this is possible. Anyones help would be much appreciated.

5d mark III download problem

Hi,
I'm having problems downloading images from a 5d mark III to Lightroom. I'm shooting raw CR2 format. When the camera is connected to the computer, a handful of files download, then an error message appears saying the remaining files can't be read.
I'm on a macbook pro with the latest OS. The canon firmware is 1.1.2, Lightroom ver. 4.2.
The same images download to the computer fine, via a card reader. When the camera is connected to an older macbook, the download is also problem free.
Any ideas gratefully recieved.

I've downloaded thousands of pictures using a direct USB port camera connection from Canon 300D, 600D, 5D MKII, and PowerShot A630 cameras without a single lost or corrupted image file, and the transfer speed is faster than a SanDisk USB2 and current HP System built-in card reader.
I can't speak for Mac OS systems, but Windows 2000, XP, and 7 OS systems have always recognized my cameras and download my images without a hitch.
One possible cause of Paul's error message is that the camera battery started to run low during the LR file transfer. Make sure the battery charge level is near 'Full' before downloading images.

5D Mark III HSS Problem in Low light

We have a somewhat serious problem with our two Mark III's...or some obscure setting.
When the light level get's too low, they over expose when HSS is on. We can slow down the shutter so it turns HSS off and everthing is perfect. But, once you speed up so HSS is on, it is way over exposed (about two stops). This happens with both cameras and an ST-E3-RT, a 600EX-RT and/or a 430EX - off-camera or on. It doesn't seem to matter what ISO setting or exposure setting, once it goes below a certain light level it over exposes. We are normally around ISO 10,000, F2.8, 1/250. At this point, flash compensation has no effect, camera exposure compensation does change it but then you can't go back to regular light levels or no flash without switching it back. Another hint is that I can change the off-camera 600EX-RT compensation on the flash itself and that will help. But again, if it goes back to regular flash, it'll be too dark.
So, there is a clear difference in exposure between HSS and regular, or no flash at low light levels.
We've used this method with the original 5D and the 5D Mark II and all was fine. This is new with the Mark III.
It is possible we have some obscure setting incorrect...hopefully. Any help would be greatly appreciated!

There's definitely something wonky about this situation. If anything, the photo should be DARKER when using HSS. And flash compensation has no effect, but exposure compensation does? That doesn't make much sense with regard to the flash power. Exposure compensation should have no effect on the flash at all if you're shooting in Av mode.
Try shooting in manual, and do a "factory reset" of your camera body and reset all custom functions.

Intermittent power problem Canon 5D Mark iii

My Canon 5D Mark iii (2 years old) has an intermittent power problem, as described below. It may simply be a question of cleaning the terminals that the battery connects to. I haven’t tried since I can’t reach them at the bottom of the battery compartment.
Details as follows:
this is a recent problem in the last 3 weeks
the problem occurs with all three Canon batteries that I use
from time to time when the power is on, the camera suddenly loses all power and displays an “empty” battery image
sometimes it happens of its own accord while no demand is being placed on the camera
but more usually it occurs at the moment of focusing (I use back focus on the * button)
it is often fixed by turning the power off and then on again. This fixes it half the time
it is always fixed by turning the power off, removing and then re-inserting the battery
needless to say this is very annoying!
Since coming back from a trip, while transferring images from the camera to my computer, I noticed that the (almost) full battery started showing “empty”.
The transfer was completed successfully, and when the camera was disconnected from the computer, the battery showed that it had lots of charge left. Very puzzling!

It sounds like either the battery terminals aren't getting a solid contact or there's a fault (something loose or grounding out) inside the camera. But if something were genuinely loose or grounding out inside the camera, then power cycling or even re-inserting batteries would probably not fix it -- which makes me suspect it's still something outside the camera.
Are any of the batteries new, or are they all about the same age as the camera?
Batteries only last a few years but it'll depend on how they were used. In other words if all three were used about the same and enough charge cycles to be at the end of their reliable life... it might be time to replace them.
It's difficult for the internal battery terminals to get dirty unless the battery itself had something on the battery iteself when you inserted it. You can try a bit of denatured alcohol on a cotton swap to reach in and clean the terminals. Also, inspect the batteries to make sure they're all clean.

Problem with S-raw from 1Ds mark III and Lightroom 2.5 (ACR 5.5)

Hello,
We develop over 100000 Raws per day using Lightroom 2.5 and a Canon 1 ds mark III. For the past six months we have been using the S-raw format for compatibility with our program Workflow. We’ve been having stability problems linked to luminosity, particularly differences in yellows, reds, oranges, and beiges.
This artefact lightens the whole of the image, which gives us several light densities within the same image series.
We’ve done several tests with photos shot in S-raw and JPEG simultaneously. The problem does not appear in the JPEGs, or in JPEGs generated by the S-raw format.
This is why we have concluded that the problem comes from Lightroom’s calculation algorithm for S-raw. This hypothesis is confirmed as the problem is only in Lightroom 2.5 (we’ve tested 5 competing programmes and have not had the same problem).
Ciao.

Problems with Lightroom should be posted in the Lightroom forum.
If you are having similar problems with some version of ACR, check the FAQ (http://forums.adobe.com/thread/311515?tstart=0) and provide more details, samples, etc... in a later post.

5D mark III lens correction problem with dark shots

Just found a new irritating problem with 5D mark III and Lightroom 4 (currently on 4.2). I shot quite a few shots in the dark over the weekend using high ISO (6400-16000), with EF 24-70 f/2.8L. If I enable the lens profile correction on the dark shots, the corners of the images all develop incredibly strong purple haze that renders the image unusable. Not enabling the correction allows me to use the images just fine. Also images that were shot with similar settings but were shot inside, with more light, don't have the purple fringing issue. Makes me wonder if this is some incompatibility between Canon's high iso noise reduction system and Lightroom's RAW processing when it does lens corrections.
Anyone else seen this?

Sulka Haro wrote:
Replicated the shot under a heavy blanket -> yes, the exposure looks the same. Whatever is causing the corner to be noisier than rest of the exposure doesn't seem to be caused by light.
At that very high of ISO you are actually seeing small differences in the sensor chip temperature due to heat from the electronics in the camera. The small amount of increased noise you're seeing in the corner at ISO 25600 is insignificant.
Sulka Haro wrote:
Interestingly enabling long exposure compensation doesn't seem to do very much to really improve the shots at these sensitivities. When enabled, the exaggerated corner noise does disappear, but also it looks like some areas in the middle of the exposure become more noisy with non-uniform noise blotches appearing instead of fairly uniform slightly higher noise pattern.
I haven't needed to use Long Exposure Noise Reduction with my 5D MKII, so have no firsthand experience. My guess is that at very high ISO settings (above 6400) a lot of what your are seeing is random noise or "shot noise," which changes from frame to frame. This causes the dark frame subtraction to "fail" in the way you are seeing. Just a guess.
There is an excellent 5D MKIII review that compares noise reduction with several other high-end camera models. The reviewer also states,
"The 5D Mark III's ISO 51200 and 102400 remain a complete mess even with strong noise reduction applied - You have to be desperate to use these settings. ISO 12800 and 25600 remain very marginal for my uses. I always shoot in the lowest standard ISO setting that will allow me to get my desired shot, but begin to cringe when settings above ISO 3200 must be employed. Your standards and applications may be different."

5D Mark III Video Problem -- Help Needed!

Hello,
Been using my 5D Mark III for video for about a month now. I noticed a problem occurring in the middle of certain shots where the color seems to shift. The problem is so slight that it will take full screen, full HD and a high level of concentration to detect. I believe the most obvious occurence is at 28 seconds where the valley below suddenly takes on a different color. Here is a video of my issue: http://www.youtube.com/watch?v=Xw9IHYkUEqQ
I run these settings:
Manual Focus
Aperture, ISO: Manually set
Shutter Speed: 1/50
1920x1080 ALL-I 24p
Picture Style: Faithful
Custom White Balance
Auto Lighting Optimizer: OFF
Highlight Tone Priority: OFF
High ISO Speed NR: OFF
I tried to see if these were detectible on the LCD screen on the camera, but to the naked eye they are not. The original .MOV files that were transferred from the camera show them.
Could it possibly be the Chromatic Aberration or Peripheral Illumination Correction? I have not disabled these, and they are the only automatic settings that I can think of that would be changing mid-shot.
I believe ISO was set to 100 for these shots.
Any ideas what might be causing this? Any suggestions would be much appreciated!
Thanks,
Max
Solved!
Go to Solution.

This looks completely normal. I don't see a problem.
Be aware that our atmosphere has diffractive properties just like a lens. When the sun is at or near the horizon it's going to bend light differently depending on the wavelength (i.e. color) of that light. Colors in the atmosphere and on the ground (since the only way it gets to the ground is to go through the atmosphere) will vary depending on where you point the camera and the position of the sun. As the sun rises it wont take such a angled path through the atmosphere and this effect is greatly diminished.

5d mark III front focus problem

my 5d mark III has a problem with front focus. I use only crosstype focus points but even cental one can't focus correctly no matter what lens I use. the problem is more significant further the subjet focused on is. tried different light conditions with the same result. Camera always front focusing significantly, so the suject is out of DOF all the time. tested lenses 50/1.4 and 24-70/2.8 L. problem persist in all AI modes (focus/servo). please could you provide any solution? thanks in advance

See: http://www.lensrentals.com/blog/2008/12/this-lens-is-soft-and-other-myths
Your 5D III will let you adjust some thing called "Autofocus Micro-adjustment" (AFMA). You can either do this gloally (for all lenses) or you can do it on a per-lens basis.
Although... if EVERY lens needs it... and needs a LOT of it... I think you might prefer to send the camera to Canon for correction.

Canon 5D Mark III Jpeg problem

Received my new 5D Mark iii today. Pretty happy so far however I have noticed a strange issue with Apple Aperture when viewing jpegs from the 5d mark iii. I noticed a white line at the top of the frame or the left of the frame on vertical shots. It is more noticeable in full screen mode in Aperture.
I opened the jpegs in PS, Preview, DPP and the Finder and none of them show this white edge line.
The other odd thing is if I export a jpeg of one of these out of Aperture and then load the exported file the white edge line switches sides of the image. Also I noticed if I save a jpeg version out of PS and then import that into Aperture I do not see the white edge line.
I tried shots using multiple lenses as well with the same result.
Seems like Aperture has some issue with 5d mark iii jpegs. Don't think it is the camera since PS, DPP and Preview don't show the same issue.
Wondering if others have noticed this same problem?

Here is another example. This one I exported to Smugmug from Aperture and no white edge in the Smugmug posting. Definitely seems to be some wierd Aperture problem.

Focus problems with Canon 1D Mark III

I have been having problems with my 1D Mark III, it take an unusually long time to focus. The problem is especially prevalent indoors. I am using a Canon 24 to 70 IS lens.

I have had the camera since it first came out, however I also aready had a Canon 20D at the time. I seemed to do better with the 20D. I recently bought a Canon 7D and it focuses much faster. I am very displeased with the 1D Mark III.
I am an experienced photographer, photography is a passion I have studied and pursued. The 20D was my first DSLR, prior to that I shot with a Nikon 2020 film camera.
The problem with the 1D Mark III is that it takes an unusually long time to autofocus. Due to this, I usually relied on the 20D. When I bought the 7D I retired the 20D and paired the new camera with he 1D for gigs (weddings, parties etc.). It is frustrating to attempt shots with the camera and have subjects wait for me to shoot.

Problem with the RAW images from Canon 5d Mark III

hope you are doing good. i need your opinion regarding a phenomena i am observing in the RAW images from Mark iii.
The following images appear to be absolutely correct in the camera and when viewed through a picture viewer.
I have tried and tested the following scenarios:
1. Used a medium speed kingston CF Card (new) and transferred the images through the USB cable supplied with the camera.
2. Thought the card might be slow OR faulty.. used Sandisk Extreme and Extreme Pro SD Cards but same result.
3. Transferred SD Card data through the builit in laptop card reader.
4. Have directly imported the images from SD Card into Lightroom 4.3, copied the data firstly to laptop HDD and then imported, copied the SD card data to an external HDD and then copied. .... same result!!
5. Have tried the same with both Win7 and Mac OS.
6. The DPP sw that came with the camera gives the error of 'Decoding Failed' with these images.
Usually 10-15 images out of 100 give this kinda pattern. so i was hoping if you can guide me what is going wrong here !!!

The camera and PictureViewer are likely showing you the embedded JPG, while DPP and LR are decoding the raw data which appears to be corrupted. Assuming you have formatted your SD cards in the camera and the issues are always in the same positions in the same images when you transfer them multiple times from the card to different computers via different methods, then the data is on the card that way.
If the embedded JPG is ok then the sensor is ok, so something between the sensor-readout and the storage on the card appears to be failing intermittently, and it’s time to talk to Canon, I think.

Problem with ACR 7 support of Canon 5D Mark III

Just purchased LR4 with ACR7 (upgrade from LR3.6 - not happy about that either, but I am mostly over it) and tried to import photos from my Canon 5D Mark III. Import feature sees all the .CR2 files but when I try to import them it complains that it does not recognize that file format. Not happy.

Unfortunately two important cameras, the Canon 5D.3 and the Nikon D800, came out during the transition between LR3/4 and PS-CS5/6 so Adobe released beta versions of LR and ACR to help tide people over, but what gets released when is kindof messy during the transition.
A major version release requires debugging and testing so the functionality, including new camera support, must be frozen earlier as compared to mid-version camera-support releases that have minimal coding changes. ACR7-beta functionality was frozen back in February so has even less camera support than ACR6.7 beta, which confused PS-CS6-beta users as well.
Just so you’re aware, there is a bug when doing extreme adjustments in the new toning model and geometric lens-corrections have been applied, so be careful with that in the new LR4.1 RC2. Eric Chan has said the bug will be fixed in the release version of LR 4.1. The same bugs exist in the final ACR 6.7 that came out within the last week, so it is unclear what the status of a bugfix is for PS-CS5 users.
Here is a forum post with more information. Also check out the other threads people refer to with other examples of the bug:
