The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Elmar-M 24mm f3.8 ASPH and the Carl Zeiss Distagon T2,8/15 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 T2,8/15 ZM is the longer of the two lenses at 92mm. The Leica Elmar-M 24mm f3.8 ASPH with a length of 53mm, is 39mm shorter. Besides being longer, the Carl Zeiss Distagon T2,8/15 ZM also has a larger diameter of 78mm compared to the Leica Elmar-M 24mm f3.8 ASPH's 41mm 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 Elmar-M 24mm f3.8 ASPH weighs 260g, which means it is 290g (52%) lighter than the Carl Zeiss Distagon T2,8/15 ZM which has a weight of 550g.
Filter Threads
The Leica Elmar-M 24mm f3.8 ASPH has a filter size of 46mm whereas the Carl Zeiss Distagon T2,8/15 ZM has a 72mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 46mm filters that we recommend you to consider for the Leica Elmar-M 24mm f3.8 ASPH:
