>>3087633Being on a different body makes no difference to how sharp the lens is. All that matters is the flange distance to the sensor - and that will be exactly correct. The connection of a Leica body and lens is nothing special. These lenses were tested equally.
The problem lies in that the Zeiss is the most optically advanced photographic 50mm around and is about £2000. The Summilux 50mm f/1.4 is around £3000 and is very optically inferior, even to Zeiss's £700 55mm.
Total waste of money on a lens on optical par to designs from the 80's.
