Hi Experts I need some advice on narrowing down my choice to shortlist the 35mm lenses to use on my Sony NEX 5n camera. Currently I am focused on getting one of the old lenses which are manual focus & will allow me to use manual or Aperture mode with the lens. So far below listed ones I have shortlisted for this choice. Please reply with your expert knowledge as to which is better choice amongst this & if there is another brand that I should consider for which I am not aware of. Here are the preferences: 1. Nikkor Ai-S 35mm f 2.0 2. Voigtlander 35mm F/2.5 Color-Skopar MC ( Type C ) Price constraints less than $300 US & aperture bigger than or f 2.8. Thanks you..
