Voigtl nder ultron vintage line 28mm f 2 aspherical vs leica summicron m 28mm f 2 asph?

Both lenses are 28mm f/2 primes for full frame, both mount on Leica M, and both are manual focus and unstabilised. On paper they're the same lens, and the site doesn't say how they differ on price, build or image quality, so I can't honestly pick a winner from these pages.

Both fit the same Leica M bodies, from the Leica M9 through to the Leica M11, so body choice won't decide it. Check your budget and how you like the lens to feel in hand, then choose between the Voigtländer Ultron 28mm f/2 and the Leica Summicron-M 28mm f/2.

If you're not sure 28mm suits you, the Street page's focal length notes explain what it's like to shoot with it.
