Friends, I've been a pro since 1967 and have been using a D850 for around six years now. I'm quite familiar with the camera and all focusing modes, but one things has eluded me for quite some time. I cannot get autofocus to accurately see my cats. Regardless of whether I am in S or C, mode, regardless of whether I am using zones or group mode, I cannot get sharp photos of my cats unless I manually focus.
I calibrate all of my lenses for back focus, and all of my images are brutally sharp at any aperture on any object (including my bird photos), but my cats have proven to be elusive.
Any suggestions?
