@klaus Sure, before I started using EAF I did most of my exposures by just using manual focus and it worked quite good. After installing EAF I had to adjust it as I needed some more flexibility as temperature changes from winter to spring ;-). So, I took off EAF, refocused manually, turned RC focus to minimum, attached EAF, set it to position zero, moved it until finally reaching maximum movement of RC (which was somewhere around 7600), defined EAF maximum steps to 7500 (so maximum RC limit couldn't be reached). Throughout many different software that I tried or use I constantly found a stepwise of 80 and and outbound overshoot backlash of 120 extremely sufficient.
None of the other software ever had any problems with these values or the maximum step limit of 7500. AAP jumped to 7500 as described as long as 7500 is defined as EAF maximum, but when increasing it, AAP never even touches 7500 or comes close to it.
And after all the resulting AAP autofocus is not as good as it could be, and as I can reach it by manually changing EAF position.
