The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 135mm F1.4 and the Sigma 50mm F1.2 DG DN Art 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. Sigma 135mm F1.4 is the longer of the two lenses at 136mm. The Sigma 50mm F1.2 DG DN Art with a length of 109mm, is 27mm shorter. Besides being longer, the Sigma 135mm F1.4 also has a larger diameter of 112mm compared to the Sigma 50mm F1.2 DG DN Art's 81mm diameter.
Below you can find a scaled side-by-side image of Sigma 135mm F1.4 and Sigma 50mm F1.2 DG DN Art to get a better idea of how their sizes compare in real life.

Sigma 50mm F1.2 DG DN Art weighs 745g, 47% (685g) lighter than the Sigma 135mm F1.4's weight of 1430g.
Filter Threads
The Sigma 135mm F1.4 has a filter size of 105mm whereas the Sigma 50mm F1.2 DG DN Art 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 105mm filters that we recommend you to consider for the Sigma 135mm F1.4:
And these are the 72mm filters that we recommend for the Sigma 50mm F1.2 DG DN Art:
Lens Mounts
Both the Sigma 135mm F1.4 and the Sigma 50mm F1.2 DG DN Art 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 .
Sony E mount.
Focal Range
Sigma 135mm F1.4 is a prime lens with fixed focal lenght of 135mm.
On the other hand, the Sigma 50mm F1.2 DG DN Art is a prime lens with fixed focal lenght of 50mm. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides a 35mm (FF) equivalent of 75mm .
