Voigtl nder ultron vintage line 35mm f 2 aspherical vs leica apo summicron m 35mm f 2 asph?

Both are 35mm f/2 manual-focus primes for full frame Leica M bodies, so they frame and shoot the same way. The main difference is the close focusing. The Leica APO-Summicron-M 35mm f/2 ASPH focuses as close as 30cm, much closer than most M lenses. The Voigtländer Ultron Vintage Line 35mm f/2 Aspherical doesn't list a close focus distance, so I won't guess at one.

If you shoot food, details or other close subjects, the Leica is the better pick. For street and everyday scenes at normal distances, the Voigtländer covers the same ground.

Both fit the same bodies, including the Leica M10 and the Leica M11. Prices aren't on either page, so check them before you buy.
