The XA is sharp enough stopped down for street photography using ISO400 film. I mean it's not as sharp as bigger lenses can be: XA's lens is the size of a button... It's been commented that being such a very light camera, we must take special care about possible camera shake... Rollei 35's using the sonnar, and Contax T3, are a bit sharper, but the Rollei 35's don´t have a 35mm lens but a longer one, and the T3 is autofocus. If the final image is a great photograph, the XA is sharp enough: lots of great photographs in history have less technical image quality than the XA can give. Between Rolleis and the T3, I'd prefer the T3 because of the 35mm lens and because it has very close focus, and that gives some funny options for fast autofocus work. Cheers, Juan
