The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Carl Zeiss Distagon T1,4/35 ZM and the Leica Summicron-M 50mm f2 for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is a crucial factor to consider when comparing two lenses. Carl Zeiss Distagon T1,4/35 ZM is the longer of the two lenses at 65mm. The Leica Summicron-M 50mm f2 with a length of 44mm, is 21mm shorter. Besides being longer, the Carl Zeiss Distagon T1,4/35 ZM also has a larger diameter of 63mm compared to the Leica Summicron-M 50mm f2's 53mm diameter.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Leica Summicron-M 50mm f2 weighs 240g, 37% (141g) lighter than the Carl Zeiss Distagon T1,4/35 ZM's weight of 381g.
Below you can find the dimension and weight table of the Standard Prime Lenses in Leica M Mount for size comparison purposes.
