Hi all,

I'd like to share results of my first focusing with the EAF and the linear algorithm: I love it!

All calculation works perfectly. I didn't use the Bahtinov mask, just positioned the EAF at the calculated position taken from the previous session without the EAF: 7600 step. After five attempts it began behave properly and I found highly repeatable focus position: 7715 steps. Every time I go back to the zero position and then I position it again at 7715. Moreover, all the time I had a proper number of stars in the area 25%-75%.

I promised to compare the algorithm with the polynomial one, but please, not today. I have several hours without the rain, so I must to use the opportunity.

Look plesae at the animation of the process, the V-curve is iconic!
