Nikor. Yup, that aught'a do it for World-class sharpness - and they'll do it with a wide open aperature! I love my Yashica Electro 35, but you have to stop it down to at least F/4 or better for a crisp one. I was reading about these deep sky wide field astrophotographers running Nikors ..was it a 90mm f/1.4? ..Something like that - and they run'm wide open!. I want a Leica. Small, quiet, reliable - with that Zeiss glass. Oh-yeah! Joe
