70-200 f2.8 AF problem

[mish757]

Have a canon 70-200 f2.8 non IS lens that is having AF issues.  My other zoom lens (24-70 f2.8) is not having any issues paired with my 5D Mk III body, so pretty sure it is an issue with the 70-200.  The problem is with the AF on closer subjects (approx. within 25 ft) - on more distant subjects, the AF is tack sharp, but when I try to focus on a closer subject, the AF won't lock.  The motor continues to hunt for proper focus.  Tried cleaning the contacts, but still have the problem.  Anyone else have experience with this issue.  Thought I would ask you experts before shipping the lens off for repairs.

I have almost the identical issue as mish757...a 70-200 2.8 non-IS with a 7D MKii that doesn't focus at all. 4 of my other Canon lenses work perfectly fine. I took the lens to the Canon Service Center and they tried it on a 7D and it worked, so you're right about it not being the lens. Are you aware of any common issues the 7D's have with this particular lens? I even updated the firmware to the latest version.

"I even updated the firmware to the latest version."

Whatever this problem is it isn't the FW.  If the lens worked on another camera, hopefully another 7D, the lens is OK.  If other lenses work on your 7D pretty much confirms the camera is OK.

You need to take both 7D and lens to the service center.  Show them what is going on with your specific gear.

Thank you for your response! The Canon service techs used a 7D to replicate, then suggested I bring both cam & lens. I read another thread in this forum where someone suggested restoring the camera's default settings...I did and so far, that seems to have done the trick. So far. 😃

Did you end up sending in your 70 to 200 to Canon? Why I’m asking is my AF doesn’t seem to be working either. Wondering how long it takes to get it back to you? Did it have to be fixed? Thinking about sending mine in but was wondering how much they charged you? Did they clean it too?
Thank You
