Using Focus convergence in Focusmax results in no focus being obtained. I let it go for about 45 or so iterations and then cancelled it. I unchecked focus convergence and focusmax obtained focus. I had a read about focus convergence, but wonder what is going wrong. It is supposed to be the ducks nuts for focus control. Any ideas out there?
Depends on what focus convergence settings you are using. The standard settings will be several magnitudes out fort he atlas's resolution. You set how many iterations of convergence you want and a target range that you want those focus points to be grouped. You have my number, give a call if my incoherent rumblings don't make sense.
