The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summicron-M 50mm f2 and the Leica SL 50mm F1.4 2026 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 SL 50mm F1.4 2026 is the longer of the two lenses at 76mm. The Leica Summicron-M 50mm f2 with a length of 44mm, is 32mm shorter. Besides being longer, the Leica SL 50mm F1.4 2026 also has a larger diameter of 74mm compared to the Leica Summicron-M 50mm f2'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 Summicron-M 50mm f2 weighs 240g, which means it is 344g (58%) lighter than the Leica SL 50mm F1.4 2026 which has a weight of 584g.
Filter Threads
The Leica Summicron-M 50mm f2 has a filter size of 39mm whereas the Leica SL 50mm F1.4 2026 has a 67mm 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 Leica Summicron-M 50mm f2:
And these are the 67mm filters that we recommend for the Leica SL 50mm F1.4 2026:
Lens Mounts
The Leica Summicron-M 50mm f2 has the Leica M lens mount whereas the Leica SL 50mm F1.4 2026 has the Leica L 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 Leica M Mount and Leica SL3-P, Panasonic S1 II and Panasonic S1 IIE for the Leica L Mount.
Focal Range
Both lenses have the same focal range of
50mm but while Leica Summicron-M 50mm f2 has the fastest aperture of
F2.0, the Leica SL 50mm F1.4 2026's widest aperture value is
F1.4.
