The type of photography that you are planning to use is an important decision factor. Here we have evaluated the TTArtisan 75mm F1.5 SB and the Leica Summarit-M 90mm F2.4 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 Summarit-M 90mm F2.4 ASPH is the longer of the two lenses at 67mm. The TTArtisan 75mm F1.5 SB with a length of 63mm, is 4mm shorter. On the other hand, the TTArtisan 75mm F1.5 SB has a larger diameter of 63mm compared to the Leica Summarit-M 90mm F2.4 ASPH's 55mm 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 Summarit-M 90mm F2.4 ASPH weighs 360g, 35% (202g) lighter than the TTArtisan 75mm F1.5 SB's weight of 562g.
Filter Threads
The TTArtisan 75mm F1.5 SB has a filter size of 58mm whereas the Leica Summarit-M 90mm F2.4 ASPH has a 46mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 58mm filters that we recommend you to consider for the TTArtisan 75mm F1.5 SB:
And these are the 46mm filters that we recommend for the Leica Summarit-M 90mm F2.4 ASPH:
Lens Mounts
The TTArtisan 75mm F1.5 SB has the M42 lens mount whereas the Leica Summarit-M 90mm F2.4 ASPH has the Leica M lens mount. Some of the latest released cameras that are compatible with these mounts are Leica M EV1, Leica M11-D and Pixii Max for the M42 Mount and Leica M EV1, Leica M11-D and Pixii Max for the Leica M Mount.
Focal Range
TTArtisan 75mm F1.5 SB is a prime lens with fixed focal lenght of 75mm. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides a 35mm (FF) equivalent of
112.5mm.
On the other hand, the Leica Summarit-M 90mm F2.4 ASPH is a prime lens with fixed focal lenght of 90mm.
