VC 35mm Ultron or Rollei 40mm Sonnar
I've been contemplating making a purchase of one these two lenses lately, though I can't quite make up my mind. Aside from the size of the lenses and an approx 1.5 stop difference, what do you guys think?
I know these lenses aren't exactly the most well used lenses but anyone who could offer some experience with one or the other (or both!) would be fantastic.
