Zeiss distagon t 35mm f 1 4 zm vs leica summilux m 35mm f 1 4?
Both of these are 35mm f/1.4 manual-focus primes for full frame, and both mount on Leica M bodies, so the choice comes down to how each one draws. The Leica Summilux-M 35mm f/1.4 is a remake of Leica's 1960s design and is soft and glowing wide open, which suits portraits and moody street shots. My site doesn't describe the Zeiss Distagon T\* 35mm f/1.4 ZM rendering, so check sample images before you decide. Either lens fits the same bodies, including the Leica M11, so pick the look you like.
