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 50mm f1.8 II 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 50mm f1.8 II with a length of 41mm, is 42mm shorter. Besides being longer, the Leica SL 50mm f2 ASPH also has a larger diameter of 75mm compared to the Canon 50mm f1.8 II's 68mm 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. Canon 50mm f1.8 II weighs 130g, 67% (272g) lighter than the Leica SL 50mm f2 ASPH's weight of 402g.
