The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Elmarit-M 28mm f2.8 ASPH and the Carl Zeiss Biogon T2,8/28 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 Biogon T2,8/28 ZM is the longer of the two lenses at 62mm. The Leica Elmarit-M 28mm f2.8 ASPH with a length of 30mm, is 32mm shorter. Besides being longer, the Carl Zeiss Biogon T2,8/28 ZM also has a larger diameter of 53mm compared to the Leica Elmarit-M 28mm f2.8 ASPH's 52mm 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 Elmarit-M 28mm f2.8 ASPH weighs 180g, which means it is 50g (21%) lighter than the Carl Zeiss Biogon T2,8/28 ZM which has a weight of 230g.

Filter Threads
The Leica Elmarit-M 28mm f2.8 ASPH has a filter size of 39mm whereas the Carl Zeiss Biogon T2,8/28 ZM has a 46mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 39mm filters that we recommend you to consider for the Leica Elmarit-M 28mm f2.8 ASPH:
And these are the 46mm filters that we recommend for the Carl Zeiss Biogon T2,8/28 ZM:
