The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Noctilux-M 50mm f0.95 ASPH and the Leica APO 50mm 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 Noctilux-M 50mm f0.95 ASPH is the longer of the two lenses at 75mm. The Leica APO 50mm f2 ASPH with a length of 47mm, is 28mm shorter. Besides being longer, the Leica Noctilux-M 50mm f0.95 ASPH also has a larger diameter of 73mm compared to the Leica APO 50mm f2 ASPH's 53mm 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. Leica APO 50mm f2 ASPH weighs 300g, 57% (400g) lighter than the Leica Noctilux-M 50mm f0.95 ASPH's weight of 700g.
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 Leica Noctilux-M 50mm f0.95 ASPH has a filter size of 60mm whereas the Leica APO 50mm f2 ASPH has a 39mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 60mm filters that we recommend you to consider for the Leica Noctilux-M 50mm f0.95 ASPH:
And these are the 39mm filters that we recommend for the Leica APO 50mm f2 ASPH:
Lens Mounts
Both the Leica Noctilux-M 50mm f0.95 ASPH and the Leica APO 50mm 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.
Focal Range
Both lenses have the same focal range of
50mm but while Leica Noctilux-M 50mm f0.95 ASPH has the fastest aperture of
F0.95, the Leica APO 50mm f2 ASPH's widest aperture value is
F2.0.
