I have a question about autofocus in 5DM4. I mean not LiveView focusing. I have problem with refocusing during session of shots. In LifeView the lens focus perfectly. My test step: I put the camera on tripod -> focusin on really contrast image (test chart by Focal) using central focusing dot. Distance between camera and target - 50. For my lens it it 3550 = 1750 mm. For shot use remote shutter release. And if i put the autofocus button, some time lens refocusing. And not always return to it initial place -> result: back or front focus. 2 of 10 attempts failed. In LifeView mode lens focusing perfectly without any refocusing.
I've tried to colibrate lens using Reikan Focal software. AF auto colibration works ok. But result for focus consistency - 2 of 10 shots failed.
How can i determine where is a problem? Camera of lens?
In real life shots i think the problem is worse. May be it's my fault...
