The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica SL 50mm f2 ASPH and the Canon EF 50mm f/1.8 STM 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 f2 ASPH is the longer of the two lenses at 83mm. The Canon EF 50mm f/1.8 STM with a length of 39mm, is 44mm shorter. Besides being longer, the Leica SL 50mm f2 ASPH also has a larger diameter of 75mm compared to the Canon EF 50mm f/1.8 STM's 69mm diameter.
Below you can find a scaled side-by-side image of Leica SL 50mm f2 ASPH and Canon EF 50mm f/1.8 STM to get a better idea of how their sizes compare in real life.
Comparison image of the Leica SL 50mm f2 ASPH and the Canon EF 50mm f/1.8 STM Size and Weight 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. Canon EF 50mm f/1.8 STM weighs 159g, 60% (243g) lighter than the Leica SL 50mm f2 ASPH's weight of 402g.
Filter Threads
The Leica SL 50mm f2 ASPH has a filter size of 67mm whereas the Canon EF 50mm f/1.8 STM has a 49mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 67mm filters that we recommend you to consider for the Leica SL 50mm f2 ASPH:
And these are the 49mm filters that we recommend for the Canon EF 50mm f/1.8 STM:
Lens Mounts
The Leica SL 50mm f2 ASPH has the Leica L lens mount whereas the Canon EF 50mm f/1.8 STM has the Canon EF lens mount . Some of the latest released cameras that are compatible with these mounts are Leica SL3-P , Panasonic S1 II and Panasonic S1 IIE for the Leica L Mount and Blackmagic URSA 12K LF , Z CAM E2-F6 II 6K and Z CAM E2-S6 II 6K for the Canon EF Mount.
Focal Range
Both lenses have the same focal range of
50mm but while Leica SL 50mm f2 ASPH has the fastest aperture of
F2.0 , the Canon EF 50mm f/1.8 STM's widest aperture value is
F1.8 .
