The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summarit-M 35mm F2.4 ASPH and the Carl Zeiss Distagon T1,4/35 ZM for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is an important deciding factor when comparing two lenses. Carl Zeiss Distagon T1,4/35 ZM is the longer of the two lenses at 65mm. The Leica Summarit-M 35mm F2.4 ASPH with a length of 34mm, is 31mm shorter. Besides being longer, the Carl Zeiss Distagon T1,4/35 ZM also has a larger diameter of 63mm compared to the Leica Summarit-M 35mm F2.4 ASPH's 52mm diameter.
The weight of a lens is as important as its external dimensions, especially if you are planning to hand hold your camera and lens combination for longer periods. Leica Summarit-M 35mm F2.4 ASPH weighs 197g, which means it is 184g (48%) lighter than the Carl Zeiss Distagon T1,4/35 ZM which has a weight of 381g.
