get another 2.8/300 on loan from CPS and look whether it reacts different. Sounds more like the camera to me maybe changed AF settings to when you got the lens.

op mentioned that this issue developed over time! my personal experience suggests that it has to be the camera because after a burst of shots (may be 5-6 shots), half are focused very well and the other half out of focus. and i mean shots in the same sequence. i had a thread going a couple of moths ago on the same subjects with photos to prove my point. both 1dmk4 and 1Dx do the same thing i find this issue very frustrating, to say the least. so, i suggest to op that it has to be the camera, not the lens. i hope he tries his lens on a different camera(hopefully on a 5D3) to find the culprit for good

cheerz.

Hi Rebel,

I'm having the same issue with the lens on other bodies.

Again I setup FOCAL and tried to mate it as best as possible to another 1DX and a 7D.

Very frustrating!!!!

I hope CPS can get this lens back to what it was when I got it. It's less than a year old.

I had a f/2.8 70-200 IS USM that went out of whack last year.  The clips that hols the lenses came loose and no amount of MA could fix it.

This is a pain but I need the lens for sports.... It's a MUST!

Best regards,

TV
