The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Super-Elmar-M 18mm f3.8 ASPH and the Carl Zeiss Distagon T4/18 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. Carl Zeiss Distagon T4/18 ZM is the longer of the two lenses at 71mm. The Leica Super-Elmar-M 18mm f3.8 ASPH with a length of 58mm, is 13mm shorter. Besides being longer, the Carl Zeiss Distagon T4/18 ZM also has a larger diameter of 65mm compared to the Leica Super-Elmar-M 18mm f3.8 ASPH's 61mm 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 Super-Elmar-M 18mm f3.8 ASPH weighs 310g, which means it is 40g (11%) lighter than the Carl Zeiss Distagon T4/18 ZM which has a weight of 350g.
