The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica SL 35mm f2 ASPH and the Carl Zeiss Biogon T2/35 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 SL 35mm f2 ASPH is the longer of the two lenses at 83mm. The Carl Zeiss Biogon T2/35 ZM with a length of 68mm, is 15mm shorter. Besides being longer, the Leica SL 35mm f2 ASPH also has a larger diameter of 75mm compared to the Carl Zeiss Biogon T2/35 ZM'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. Carl Zeiss Biogon T2/35 ZM weighs 240g, 40% (160g) lighter than the Leica SL 35mm f2 ASPH's weight of 400g.
Filter Threads
The Leica SL 35mm f2 ASPH has a filter size of 67mm whereas the Carl Zeiss Biogon T2/35 ZM has a 43mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 67mm filters that we recommend you to consider for the Leica SL 35mm f2 ASPH:
And these are the 43mm filters that we recommend for the Carl Zeiss Biogon T2/35 ZM:
