The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Thypoch 35mm f2 ASPH and the Voigtlander 50mm f3.5 I 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. Voigtlander 50mm f3.5 I is the longer of the two lenses at 45mm. The Thypoch 35mm f2 ASPH with a length of 27mm, is 18mm shorter. Besides being longer, the Voigtlander 50mm f3.5 I also has a larger diameter of 52mm compared to the Thypoch 35mm f2 ASPH's 40mm 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. Voigtlander 50mm f3.5 I weighs 150g, 24% (49g) lighter than the Thypoch 35mm f2 ASPH's weight of 199g.
Below you can find the dimension and weight table of the Standard Prime Lenses in Leica M Mount for size comparison purposes.

Filter Threads
The Thypoch 35mm f2 ASPH has a filter size of 39mm whereas the Voigtlander 50mm f3.5 I has a 34mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 39mm filters that we recommend you to consider for the Thypoch 35mm f2 ASPH:
And these are the 34mm filters that we recommend for the Voigtlander 50mm f3.5 I:
Lens Mounts
Both the Thypoch 35mm f2 ASPH and the Voigtlander 50mm f3.5 I has the same Leica M lens mount. Some of the latest released cameras that are compatible with the Leica M lenses are Leica SL3-P, Panasonic S1 II and Panasonic S1 IIE.
Focal Range
Thypoch 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.
On the other hand, the Voigtlander 50mm f3.5 I is a prime lens with fixed focal lenght of 50mm.
