I too hope the 45 is good. That's one thing I am lacking - an AF prime in the 75 - 90 range.I'm trusting my original analysis and not getting the 12 for right now. I'd rather spend the money on the 25 and 45 when they are released. I want the new 45mm to be a good lens or I can rebuy the 45 macro.
The 25 is, I think, a certain target for me, but it's a 45 first. I will likely upgrade my camera in the next 6 months, and want to see what the rumored GF is like.
