Hi Petkal
I searched in the forum with no luck - could you please repost the process or a link to your focus test with four batteries?
Thanks
Hi B., that is certainly not my "method", and three staggered objects (batteries, pop cans, small bottles, etc.) have been used since the time immemorial to do a quick and simple verification of AF accuracy. I do it as soon as a new lens or camera comes out of the box, in order to see if I need to return it, or take it to Canon for service, and also to establish a baseline for the AF calibration of that particular piece of equipment. If I encounter some issue with that equipment later on, I can always go back to the baseline and see if anything has changed.
I do those things at MFD for starters, and later I do AF checks at much longer distances, say 30-40 ft, as needed.
Incidentally, I've gone back to shooting leucistic Sea hawks with 1DX + 400 DO MkII today, and the results are as expected again. Therefore I am inclined to think that a combined effect of several distractions yesterday was to diminish my concentration and steadiness of the handolding, resulting in a slew of consistently soft shots. Can not be anything else. The commissioning program for 400 DO MkII continues, it ain't over yet.
