All - I'm using a 6D and my go-to lens is the Canon EF 24-70 2.8L USM. I'm finding that the AF doesn't work well. It's chasing, sometimes not locking for several seconds, and the lens produces some vibration during the process. On a different lens (EF 35 1.4L), I don't have this problem; AF is quick, smooth, assertive.

Am I correct to assume that the problem lies with the lens and not with the camera? And does my description sound familiar to anyone?

I have the 24-70 f/2.8L version II, and had problems with AF consistency on my 6D. I sent in to Canon to have them do a complete calibration and adjustment. Even as a CPS member, there was still some significant cost (I think it was maybe between $100 and $200). But, when I got the lens back, it was completely different. Accurate, fast, consistent autofocus. Just my experience.

i have had my canon 24-70 f2.8 II for almost 4 yrs. and never had a single issue with it, it is razor sharp. this is my go to lens and have been using the heck out of it from the day one!!! i didn't know anything about people having focus issue with this lens...good to know that!
