As most of us know the SL's viewscreen is unique, with its coarse central microprism and fine microprism over the rest of the screen area. Of these three cameras the SL was by far the easiest to focus at f/9.5, using the fine microprism area. No contest. I have one SL with the plain matte screen and the results are the same: the microprism screen is by far the easiest. -- Doug Herr Birdman of Sacramento http://www.wildlightphoto.com on 12/20/05 1:32 PM, Frank Dernie at Frank.Dernie@btinternet.com wrote: > Maybe my experience is unusual but even before autofocus I used plain > ground glass screens for focussing.
