The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Thambar-M 90mm F2.2 and the Leica APO 90mm 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 Thambar-M 90mm F2.2 is the longer of the two lenses at 90mm. The Leica APO 90mm f2 ASPH with a length of 78mm, is 12mm shorter. On the other hand, the Leica APO 90mm f2 ASPH has a larger diameter of 64mm compared to the Leica Thambar-M 90mm F2.2's 57mm 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.
Below you can find the dimension and weight table of the Telephoto Prime Lenses in Leica M Mount for size comparison purposes.

The Leica Thambar-M 90mm F2.2 has a filter size of 49mm whereas the Leica APO 90mm f2 ASPH has a 55mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 49mm filters that we recommend you to consider for the Leica Thambar-M 90mm F2.2:
And these are the 55mm filters that we recommend for the Leica APO 90mm f2 ASPH:
Both the Leica Thambar-M 90mm F2.2 and the Leica APO 90mm f2 ASPH has the same Leica M lens mount. Some of the latest released cameras that are compatible with the Leica M lenses are Leica M11 Monochrome, Leica M11 and Leica M10.
Both lenses have the same focal range of 90mm
but while Leica Thambar-M 90mm F2.2 has the fastest aperture of F2.2
, the Leica APO 90mm f2 ASPH's widest aperture value is F2.0
