hmm, interestingly enough, I met with Chris today to drop off the 15 heliar, and tried his BESSA R; it seemed very easy to focus compared to my RD1. the only other RF I still have is a TOPCON fixed lens and it also is a little easier to focus; maybe its the RD1 I have had a problem with; having said that, I did not seem to get any missed shots with my serenar 50 1.2 previously, so....heck, I am not sure. I will try shooting a *gasp* film with my TOPCON to see if I get good results...
Interesting that my eyesight (as of last month) is 20/20...!?!
