The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 50mm F2 C and the Leica SL 35mm f2 ASPH 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 Sigma 50mm F2 C 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 Sigma 50mm F2 C's 70mm diameter.
Below you can find a scaled side-by-side image of Sigma 50mm F2 C and Leica SL 35mm f2 ASPH to get a better idea of how their sizes compare in real life.
Comparison image of the Sigma 50mm F2 C and the Leica SL 35mm f2 ASPH Size and Weight 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. Sigma 50mm F2 C weighs 350g, which means it is 50g (12%) lighter than the Leica SL 35mm f2 ASPH which has a weight of 400g.
Below you can find the dimension and weight table of the Standard Prime Lenses in Leica L Mount for size comparison purposes.

Filter Threads
The Sigma 50mm F2 C has a filter size of 58mm whereas the Leica SL 35mm f2 ASPH has a 67mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 58mm filters that we recommend you to consider for the Sigma 50mm F2 C:
And these are the 67mm filters that we recommend for the Leica SL 35mm f2 ASPH:
Lens Mounts
Both the Sigma 50mm F2 C and the Leica SL 35mm f2 ASPH has the same Leica L lens mount . Some of the latest released cameras that are compatible with the Leica L lenses are Leica SL3-P , Panasonic S1 II and Panasonic S1 IIE .
Focal Range
Sigma 50mm F2 C is a prime lens with fixed focal lenght of 50mm.
On the other hand, the Leica SL 35mm f2 ASPH is a prime lens with fixed focal lenght of 35mm. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides a 35mm (FF) equivalent of 52.5mm .
