Thanks Rob, that's about what I found on these when on the ist-D. It's nice to have the bright finder but if it won't focus for me anyway it's no advantage. The thing is I never had a problem wide open with the M on film. The _good_ thing is the FA50/1.7 seems to really shine when used on the digital. Live and learn. I happy now and I'm sure someone will enjoy the A.
