The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Noctilux-M 50mm f0.95 ASPH and the Carl Zeiss C Sonnar T1,5/50 ZM 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 C Sonnar T1,5/50 ZM with a length of 63mm, is 12mm shorter. Besides being longer, the Leica Noctilux-M 50mm f0.95 ASPH also has a larger diameter of 73mm compared to the Carl Zeiss C Sonnar T1,5/50 ZM's 56mm 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 C Sonnar T1,5/50 ZM weighs 350g, 50% (350g) lighter than the Leica Noctilux-M 50mm f0.95 ASPH's weight of 700g.
