What are the alternatives to the voigtl nder ultron vintage line 35mm f 2 aspherical?
The closest alternative I can point you to is the Voigtländer Ultron Vintage Line 28mm f/2 Aspherical. It's from the same line, has the same f/2 aperture, and is a full frame prime. It's wider, so compare it if you want more of the scene in frame.
My page for the 35mm only lists the Leica M bodies it fits, so I can't give you a full set of other 35mm lenses for that mount. For a different focal length with a similar job, the lens guide suggests a 50mm f/1.8 on full frame. It frames more tightly, but it's a sensible choice for low light, people and food.
