The Sony FE 35mm f/2.8 Sonnar was previously evaluated on this scene and that series published in Guide to Mirrorless (see the Red Barn aperture series).
But I wanted to see if the Leica 35mm f/1.4 Summilux-M ASPH and Zeiss ZM 35mm f/2 Biogon rangefinder lenses could do any better on the Sony A7R than the native Sony 35mm f/2.8 Sonnar.
