The 70~300mm 1/125 @∱11

Finding the AF of the 80~400 wanting. Will need to "calibrate" it to the bodies. That tree rat shot is soft where it shouldn't be. The eye should be sharp, instead the rear whiskers are in focus. Used a cat's whiskers to be sure, first AF then manual, big difference in focus point!
 
AF vs. Manual. Top is with AF, both shots with camera tripod mounted. 400mm. ∱5.6, 1/4000 sec. ISO 800. Slight but noticeable in the unscaled images.

To clarify post #2, the squirrel shot posted was with the 70~300, some others with the 80~400 were not as sharp. Lucy as test victim, 80~400mm in the short end of the range. AF clearly "back-focusing" in AF mode.

Yep, did it yesterday but haven't gone out to try it. The D7200 has no provision for it, durnit.
 
I lied! the D7200 has fine tune as well. Just checked. I took a vlogger's word for it that the feature started with the D7500 in the crop sensor bodies.

I bought one of these and used my camera's "AF micro adjustment" menu to correct slightly front focusing on the far end of one of my tele lenses when used with my Canon 5D IV, which is a DSLR.


Interestingly, my R5, which is mirrorless, doesn't have any provision for micro adjustments, I assume because it's mirrorless. Luckily (so far) I've not had any issued with focus with any lenses on the R5. Even my EF lenses with an adaptor seem to focus just fine.
