Canon Auto Focus

Hi All, I was using my Canon 24-70 with the Metabones MK IV adapter. When I put the lense into auto focus and then use the push to auto focus button, the lense would rack focus back and forth but never grab it. Just curious if 1) Is this something that can even be done or does it only work with native E mount lenses and 2) If it should work what am I doing wrong  FS7 has FW2.0 and Metabones has current FW. Thanks.

I can confirm that there is still no iris flicker problem with M/B (speedbooster) FW V4.1 PLUS FS-7 FW V2.1. All seems to be running smoothly, and with a snappier feeling menu access/navigation. If you read the thread about FW 2.1 'bugs' in detail, it seems as though almost all the issues were caused by good ol' operator error of some sort or another. I personally recommmend installing the FW update. Cheers, jason

    Should I spend the $280.00 to have Canon fix my 70D auto-focusing issue? Or just return back to my very much trusted Rebels?

    Very much appreciate your taking time to send a response. As a new user I wasn't sure if anyone would bother. Allow me to add a little more to my first post. I fit in that niche between amateur and a person with clients. For over 10 years I have covered events for a non-profit agency capturing the look and feel of 20+ events per year and was given permission to purchase a few cameras over the year. My decision from the beginning was to use the Canon Rebel. Images were spot on and only once did I have an issue with one of them (after shooting outside events in 105 degree temps for 3 days).
    So, when I retired a year ago it was for me a pretty simple choice to get a Canon for myself - especially since at that time the 70D was on the cover of magazines and was very highly touted. I also did a lot of desktop publishing and photo editing which helped me realize I wanted the best sensor, sharpness, resolution and lens I could afford - the 70D. My post was actually a result of reading many online responses including your very informative replies about the 70D focusing issues. My biggest concern is that I will spend several hundred dollars and maybe, just maybe get back a camera which captures better focused images, but still not as sharp as the lower end Rebels I was using. I had hoped to purchase my first "L" lens and really get excited - not repair the most expensive camera I've bought to date.
    Thanks again and before it gets noted by someone...yes, I should have pushed this issue sooner and then at least the warranty would have covered the cost. An expensivve lesson learned. But I will have to add that at least one authorized Canon repair dealer told me they have had several folks feel like I did - that it was the photographer/me as a new user having the issue and not the camera. I now know it's my camera.
    Let me clarify that I don't own a 70D, so anything I say about it is from watching what others have said, mainly in this forum. But it is disconcerting to see so much complaint about a camera that's supposed to have an innovative focusing system. One is strongly tempted to suspect that they went overboard in trying to make the camera serve both still  photographers and videographers.
    That said, I'm not a great fan of the Rebel line, because they lack autofocus microadjustment and I have at least one otherwise excellent Canon lens that would be useless without it. (The 70D does have AFMA, a point in its favor.)
    As far as spending the $280 for the repair, I understand why it's a hard call. If I were in your shoes and were convinced that Canon understands the issue and would fix it correctly and permanently, I guess I'd go for it. If you don't think they do, but fell that you need something a cut above the Rebels, this may be a good time to buy a leftover or refurbished 7D. Even though I now have a 5D3, I still use my 7D's a fair amount and have been very happy with them. And the 7D2 has gotten such a favorable reception that's it's almost bound to make more 7D's available at a decent price.

  • Canon 6D Back button auto focus and ISO settings

    I was curious why when I am shooting in TV mode and I am using the back button auto focus that the camera will automatically change the ISO setting that I set. Is there something that I have missed in the settings or is this an automatic feature that can not be turned off?

    Sounds like you have safety shift set in a custom function
    Check C.Fn 1-6 Safety Shift - you may have it set to 2 - ISO Speed

  • Canon 5D markIII change M focus to Auto Focus

    Hi there
      It's probably a very stupid question as I'm a total newb,
      but I'm trying to set my auto focus mode to "one shot" on my canon 5D mark iii but it's stuck in M focus. I've set it to reset to factory setting but it's still  the same. how to I change that? 
    Solved!
    Go to Solution.

    Hi,
    Don't want to sound harsh because we all were in the exactly same place as you, at one time or another. But it's obvious from your questions that you have little experience with Canon DSLRs and the 5D Mark III is a complex and fairly advanced model. I'd hate to see you get frustrated and not have fun using it.    
    So do yourself a big favor.... spend some serious time studying the camera manual and also consider buying and reading one of the guide books for your camera.  I always make a point of getting a guide book, anytime I get a new, unfamiliar camera. (Others are probably good, too, but I can recommend authors David Busch, Micheal Guncheon and Charlotte Lowrie from personal experience).
    Further, if you have limited photography experience, you also might consider getting a copy of Bryan Peterson's "Understanding Exposure". These will help you get up to speed with the camera and enjoy using it much sooner.
    Another way to change those settings is by pressing the Q button on the back of the camera. This will call up a "quick access" panel on the rear LCD screen, showing all the major settings of the camera. Use the joystick to navigate to the "Autofocus" box on that screen, press "set" button to enter that section, then scroll through the choices (One Shot, AI Focus, AI Servo) until the one you want is highlighted, then press "set" once again. Now a half-press of the shutter release button or a tap on the AF-On button will take the camera out of this screen and setup mode, back into "shooting" mode.

  • Canon EF-S 18-55 random auto focus problem

    Hello I have been working with Canon EF-S 18-55 NON IS lenes and have found a problem I can't seen to solve. The problem is that I do get auto focus but at certain points it will not focus. I have changed the board with a known good one, The motor assembly, The contacts with good looking ones from working units but not the contact strip as they look good. The assembly moves freely with little resistance. I have also seen this problem on IS versions too but mainly on the non IS versions. I'm looking for any other suggestion that might solve the problem.

    Yes I do and have had very good success in repairing them but I have a few that just defy me and have this problem.

    I had the same problem. I make my AF work going to Menu / AF mode and selected Live mode. On Quick mode the AF did not work. I change the settings without realise it. Now my AF is working fine.

  • Having trouble auto-focusing using the digital display.

    My Rebel T3 seems to have problem auto-focusing indoors when using the digital display .  Seems to work fine using the viewfinder.

    Live View focusing is always going to be very slow.  It is not just your camera.

  • Canon T3I focus using video

    What's the trick to utilize auto focus when in video mode?  I can focus manually and have to keep re-focusing.  Help!   

    When shooting video try to practice manual focus.

  • I have a EOS 30D with EFS 17-85mm lens. Error 99 and now the auto focus is not working

    The 30D started a month ago to show Error 99 and not I have lost auto focus?  Any suggestons!

    Error 99 is not specific. It just means something is wrong and the camera is unable to function, but doesn't give any clues what the fault might be.
    I agree with cleaning the lens-to-camera contacts and the idea of trying the camera with another lens and the lens with another camera, to see if you can determine which is at fault.
    It also may help to reboot the camera and/or reinstall the firmware. Maybe something has gotten hung up in memory or some instructions have gotten corrupted.
    To reboot the camera simply turn the camera off, remove all batteries (including the small time/date battery), turn camera on and press shutter release button once (nothing will happen, this is just to clear any remaining power stored in the circuitry). Then turn the camera back off, reinstall the batteries, turn camera on and check the date/time. If it needs resetting, then you got a proper reboot. You likely will need to reset things in the menu and the custom functions.
    While doing the above, it's a good time to replace the time/date battery. If your 30D still has the original, it may be sorely in need of replacement. Those little silver button batteries are widely available and easily found.
    To reinstall the firmware, go to the Canon website, search for 30D model and look for the software page. The latest version of firmware should be available there for download, along with instructions how to install it. Follow the instructions very carefully. It's not difficult to do, but must be done right or there's risk of "bricking' the camera.
    There's no guarantee that either of these will help... but they might, plus are free and relatively easy to try yourself.
    If none of the above helps, you'll likely need to have the camera looked at by a professional repair tech.

    "the main round on/off button and where u switch settings you want to use.....and the other  one  is the af/m button on the left"
    You say you never dealt with the AF/MF switch on your original lens that you had for 3 years. You probably just never noticed it.
    But........ In the late 1980's Canon did manufacture 3 Auto Focus lenses for EOS cameras that had no Manual focus ring or AF/MF switch, so it is possible.

  • 4k video app for professional use, auto focusing issue

    Hello Sony Z3 support,
    I would like to address the developers of 4k video camera app. I know it's a stand alone application that shoots 4k.
    I shoot video professionally and now experiencing the change from full hd to 4k.
    Sony has the best 4k camera on the market these days, and me personally, I purchased this phone to be able to shoot 4k video using the smartphone.
    Currently 4k app lacks some pro features to make the shooting, but that's ok. The main issue here is its auto focusing whenever picture changes. So many shots were ruined by this issue. It's not a bug or hardware problem, it's just lack of possibility to disable the auto-focus.
    My feature request about 4k video camera app is as simple as this:
    - ability to select between auto and manual focus
    - focusing on tap
    It's been already implemented on regular photo/video app, but not in 4k video app. Without this feature this 4k camera cannot be used for professional purposes.
    I know it wasn't designed for a pro video, but I'm talking about something that may change the market like Canon DSLRs did with Full HD video few years ago.

    you should contact Sony Xperia Support, and let them know about your request.

  • How do I stop Firefox from auto-focusing on text boxes?

    How do I stop Firefox from auto-focusing on text boxes? Sometimes as a page is loading, I scroll down the page...only to have the page jump back to where there is a text box, with a blinking cursor, after the page is finished loading. It is an annoying feature and I want to turn it off.

    Some pages use an onload event to set the focus to a text area or search field.
    You can try NoScript to see if that blocks it.

  • [SOLVED:] SLIM not reading slim.conf (no password auto-focus)

    Yesterday I began having issues with SLIM.  I'm not sure if they're related, but  while running Puppy , I inadvertently deleted the desktop icon for my Arch home directory on /dev/sda8.  I rebooted Puppy and it reappeared.  After running Puppy, something went wrong with my clocks (system and hardware) and the times were all wrong.  I fixed that with NTPD.  I currently dual boot Arch and Windows 7 from the hard drive, and occasionally from a USB stick, Puppy Linux.  I'm using an ASUS K50IJ laptop.  I run Xfce4.  I do not have any disk encryption enabled.
    When I boot up, the SLIM login appears as normal, but rather than password auto-focus, I'm prompted for a username.  If I enter the username and hit return, I'm still staring at the username prompt.  After three or four iterations of entering a username + enter, I finally get a password prompt and can log in.
    I have tried:
    1.  Reinstalling archlinux-themes-slim
    2.  Uninstalling archlinux-themes-slim and slim, then reinstalling slim
    3.  Removing old Xfce4 & Xfwm sessions
    4.  Removing slim.conf and entering a pristine version.
    5.  Reviewing /var/log/slim.log files for oddities.  I found one:
    Before the trouble started, I the message in the log was:

    I solved this - slim was not the last daemon I started in rc.conf.  By moving it to the end, I get password auto-focus and everything works.
    Now my rc.conf looks like
    # DAEMONS
    DAEMONS=(syslog-ng dbus acpid @network @wicd @openntpd @cupsd @crond slim)
    I found this recommendation in the Display Manager wiki page while researching the problem:
    Ensure you start the display manager last in the DAEMONS array, otherwise X will later allocate a tty device which was previously claimed by Getty (see /etc/inittab). Not placing the display manager at the end can cause X crashes, and is therefore unsupported.
    I'd just been lucky before that there wasn't a conflict.
    There is a "flicker" during login where I'm shown the XFCE splash, then the SLIM splash again, then the XFCE desktop.  Not sure what's going on there, but it's no big deal.
    Cheers,
