Was thinking about getting the 35 f2, but after a bit of playing around with my zoom, the 15mm difference between my cheap and great 50mm 1.8 does not seem that much at all. maybe just a step or two back would yield the same view. however, many people seem to gush about the "secret" close focus ability of the 35 f2... Anybody care to elaborate on this or provide sample pictures to show its versatility? Thanks!
