The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox 28mm F4.5 L and the Leica Summicron-T 23mm 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 Summicron-T 23mm f2 ASPH is the longer of the two lenses at 37mm. The Viltrox 28mm F4.5 L with a length of 20mm, is 17mm shorter. Besides being longer, the Leica Summicron-T 23mm f2 ASPH also has a larger diameter of 63mm compared to the Viltrox 28mm F4.5 L's 60mm 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. Viltrox 28mm F4.5 L weighs 60g, which means it is 94g (61%) lighter than the Leica Summicron-T 23mm f2 ASPH which has a weight of 154g.

Lens Mounts
Both the Viltrox 28mm F4.5 L and the Leica Summicron-T 23mm 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
Viltrox 28mm F4.5 L is a prime lens with fixed focal lenght of 28mm. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides a 35mm (FF) equivalent of
42mm.
On the other hand, the Leica Summicron-T 23mm f2 ASPH 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.
