I am interested in a Bessa R3A. Looks like a nice camera, good features, 1:1 viewfinder, and a few more bells and whistles over my QL17. Would there be any reason to choose a R2a ?? They are both the same price, so am I missing something ?? I did notice that the r3a does not have 35mm frame lines. Lens choices in the area I am interested in are 40mm F1.4, 35mm F1.7, or the nokton 35mm F1.2 Also as far as the Nokton 35mm F1.2 is it really worth the extra dough.
