It really needs to be closed down to f5.6 to get the resolution of the other lenses. And since the 35mm is a standard lens for a lot of street work, this is a problem. The 28mm on the other hand is excellent, and I use it as my normal walking around lens. The 45mm is even sharper. And of course the 90mm is often rated as one of the best around.
Black cameras attract less attention.
It would be great if the other lenses were also available in black. I've used it in below zero weather with the extra battery holder without a problem. The camera has never jammed, misfired, or malfunctioned in any way. This really does make a big difference when you're working quickly. According to the MTF charts, the 45mm and the 90mm are the best.
