The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 23mm F1.4 DC DN C and the Sigma 20mm F2 DG DN C 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 23mm F1.4 DC DN C is the longer of the two lenses at 77mm. The Sigma 20mm F2 DG DN C with a length of 72mm, is 5mm shorter. On the other hand, the Sigma 20mm F2 DG DN C has a larger diameter of 70mm compared to the Sigma 23mm F1.4 DC DN C's 66mm diameter.
Below you can find a scaled side-by-side image of Sigma 23mm F1.4 DC DN C and Sigma 20mm F2 DG DN C to get a better idea of how their sizes compare in real life.
Comparison image of the Sigma 23mm F1.4 DC DN C and the Sigma 20mm F2 DG DN C 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 23mm F1.4 DC DN C weighs 340g, which means it is 30g (8%) lighter than the Sigma 20mm F2 DG DN C which has a weight of 370g.
Filter Threads
The Sigma 23mm F1.4 DC DN C has a filter size of 52mm whereas the Sigma 20mm F2 DG DN C has a 62mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 52mm filters that we recommend you to consider for the Sigma 23mm F1.4 DC DN C:
And these are the 62mm filters that we recommend for the Sigma 20mm F2 DG DN C:
Lens Mounts
Both the Sigma 23mm F1.4 DC DN C and the Sigma 20mm F2 DG DN C has the same Leica L lens mount . Some of the latest released cameras that are compatible with the Leica L lenses are Leica TL2 , Leica TL and Leica T Typ 701 .
Sony E and Fujifilm X mounts.

Focal Range
Sigma 23mm F1.4 DC DN C is a prime lens with fixed focal lenght of 23mm which has an effective (full-frame 35mm equivalent) focal range of
34.5mm when used on a APS-C / DX format camera.
On the other hand, the Sigma 20mm F2 DG DN C is a prime lens with fixed focal lenght of 20mm. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides a 35mm (FF) equivalent of 30mm .
