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 Noctilux-M 50mm f0.95 ASPH 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. Leica Noctilux-M 50mm f0.95 ASPH is the longer of the two lenses at 75mm. The Carl Zeiss Distagon T1,4/35 ZM with a length of 65mm, is 10mm shorter. Besides being longer, the Leica Noctilux-M 50mm f0.95 ASPH also has a larger diameter of 73mm compared to the Carl Zeiss Distagon T1,4/35 ZM's 63mm 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. Carl Zeiss Distagon T1,4/35 ZM weighs 381g, which means it is 319g (45%) lighter than the Leica Noctilux-M 50mm f0.95 ASPH which has a weight of 700g.
