Try making 30 images all at +7 and running AFC-5 Auto-Focus consistency. Send me the resulting graph. LA/FT MAs with the 2X TCs are the most challenging for many reasons.

I am nearly going nuts with my 1DX2 and 400 DO II with 2X III. The focus is inconsistent and I thought I had it AFMA’d only to find that it can’t possibly be. I’ve gone through this repeatedly with AI servo, and one-shot, higher shutter speeds, thinking shake but to no avail. A large sample suggested +9, then another attempt +4 and today it seems it might even be slightly negative. Some live view shots today appeared to be slightly back focused so I’m just about ready to …..
