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 60mm f2.8 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 60mm f2.8 ASPH is the longer of the two lenses at 89mm. The Sigma 50mm F2 C with a length of 68mm, is 21mm shorter. On the other hand, the Sigma 50mm F2 C has a larger diameter of 70mm compared to the Leica 60mm f2.8 ASPH's 68mm diameter.
Below you can find a scaled side-by-side image of Sigma 50mm F2 C and Leica 60mm f2.8 ASPH to get a better idea of how their sizes compare in real life.

Filter Threads
The Sigma 50mm F2 C has a filter size of 58mm whereas the Leica 60mm f2.8 ASPH has a 60mm 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 60mm filters that we recommend for the Leica 60mm f2.8 ASPH:
Lens Mounts
Both the Sigma 50mm F2 C and the Leica 60mm f2.8 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 .
Sigma 50mm F2 C is also available in the Sony E mount.
Focal Range
Sigma 50mm F2 C is a prime lens with fixed focal lenght of 50mm.
On the other hand, the Leica 60mm f2.8 ASPH is a prime lens with fixed focal lenght of 60mm which has an effective (full-frame 35mm equivalent) focal range of 90mm when used on a APS-C / DX format camera.
