The 45-90 f/4.5 D - They said Q3 '08 as of now.
The af points are almost on top of each other, not sure who would even use the side points.
It's glass, glass, glass.
I know most people want better AF, ok, and leaf shutters, ok, but fill the line with fast glass.
Mamiya previously 45mm 2.8's, 80mm 1.9's, 110 2.8's and make sure they are sharp wide open
110 is the hole in most of these lines especially since all of the sensors have a crop factor.
Everytime I even have a whsiper of a thought of changing cameras, I look at the lens lines and few are as fast as my old Contax's so I just don't bother.
For me it's the glass, no mirror slap and sharp wide open.
I may not shoot that much at F2.2 at a 60th but when I do it's a lifesaver.
