6D mk1 focusing problems?

    Hi All,

    I've got a 6D, which is my main body and have always had problems with the AF.

    Does anyone have any solutions to combat this? Or is it just the camera?

    For moving subjects, I use Al Servo, on automatic selection.

    I have tried on multiple lens, everything from the 70-200 F2.8 to a nifty fifty, but all have the same results. I find that once it's focused on a subject, and I am using continues shotting, it fails to refocus on any movements.

    Any suggestions would be greatly appreciated.

    Many thanks,

    George

    I had a 6d Mk1 when was a Canon user. I shot a couple of airshows with it (using a Sigma 150-500) and found it challenging. The AF is fairly basic on the 6d with only the centre point being especially useful for tracking. Saying that, it does the job if you can keep the centre point over your subject.

    Yep - it's a problem! :(

    Don't know if the Mk2 has this problem cured but I'm not going for the Mk2 as apparently there are noise issues. The focusing is a frustrating problem with the camera, not the lenses.

    I put up with it though for one good (I think!) reason - it makes me spend longer composing and creating and preparing for shots. By way of explanation, I was shooting point to point racing yesterday and had a fair few out of focus but many less than previous times because I have spent more time working out where to stand and composing before shooting, thus getting around the problem better.

    I use the single centre spot for focusing but in low light especially when flash has to be used it can take a good half second to focus. I've just learned to live with it as I really like the camera and am thinking of buying a second one for my son to use (instead of the ancient 5DMk1 which I still have). In good sunlight behind me I rarely have focussing issues.

    Returning your issue and suggestions, with the point to point photography and other stuff I do, I can usually tell when it's going or will be going out of focus and just have to pause and give the camera another second to sort itself out. I don't know for certain but I think it focuses more quickly when shooting in jpeg mode as opposed to raw. And, as Jason mentions, using just the centre spot seems to work well too.

    I had a 6D. It was a great portrait / landscape body.
    However I spend most winter weekends shooting football matches and the 6D couldn't hack it because of the basic focussing system. It's not a sports camera.

    The 6D has an excellent sensor with great low light capability but mediocre AF for action - it's just one of those things you need to work through. The camera, with 11 AF points of which only one is cross-type - the most sensitive to motion, was not designed for shooting action photos (races, sports, etc.). For that you need a camera having a lot of cross-type AF points such as the contemporaneous 7D that has 19 cross-type AF Points and certainly later models having more cross-type AF Points.

    However, there are some optional steps you can take, specifically using Custom Functions II-1, II-2, II-3, and II-4 that let the shooter expand beyond simply putting the camera in AI Servo AF.

    More info can be found in your manual or here: www.learn.usa.canon.com/resources/articles/2012/eos6d_travelcam.shtml

    Glad I am not the only one finding problems! Centre point works well for me too.

    Learn the limitations of your camera/lenses and become proficient utilizing their strengths and your photos will always satisfy you. If there are specific situations, like sports, that you just have to give it a go, you will be more comfortable with what you can and can't do and be in a better position for deciding whether a particular camera or lens is holding you back.

    I only ever use the centre point, its extremely fast and accurate and quick enough for BIF and aviation especially in poor light conditions. Never use the other focus points there useless.

    I have even had good focus lock in moonlight using centre one

    Wont make much difference, 6D is well known for poor focusing on the outer focus points, as said the centre one is excellent but any 6D user will soon suss it out
