Zeiss 35mm f/1.4 Distagon on the a7r
Here is the newest Zeiss lens for the Leica M system. It is a Distagon 1.4/35mm ZM lens - Carl Zeiss' fastest lens for rangefinder cameras. We stopped by the Zeiss booth at Photo Plus and tried it out on the Sony a7r with a close-focus adapter. Voigtlander makes a better version of the adapter but this one works for us.
The 35mm Distagon ZM feels like a fine piece of machinery. The aperture from f/1.4 to f/18 have soft click stops. The focus ring is smooth, well damped, and pleasing to use - we prefer it to the Otus' ring. The lens is dense and heavy for such a small size thanks to the all metal construction. The 35mm Distagon ZM is deceptively heavy as the 85mm Otus ZE is deceptively light.
