I think when it comes down to it ideally I'm looking for the most compact, fast, 35m lens i can get my hands on that's black (for discretion) and not over $900 (aus).. ideally. Is there an option to get the ziess biogeny lens in the ad repainted .. and would that be extremely costly?
compact, fast, cheap, 35mm...
These are the words you would describe a Voigtlander 35mm f/1.4. It's very compact, and fits ur budget very nicely. The speed is there if you need it, stop it down to 2.8 and you have a very sharp lens.
I know some people don't like the lens, and it isn't the best 35mm out there, but you can't beat the price! Wide open it can be a bit soft, but on film I don't think it matters. The distortion is noticeable when u put straight lines on the edges of ur frame, and the bokeh can be busy in some circumstances.
I had two of that lens, and they never failed me. Now... if on the other hand, u r looking for top quality, and could do with a stop slower, then I'd highly recommend the Zeiss Biogon 35/2, you may find a used one in good shape for the budget. It's got zero distortion, more sharpness than you'll need, and pleasant bokeh. It's contrasty, which can be a hit or miss for u. For me, it's my favorite and most used lens.
