The type of photography that you are planning to use is an important decision factor. Here we have evaluated the SG-image AF 35mm f2.2 and the Leica APO-SL 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 APO-SL 50mm F2 ASPH is the longer of the two lenses at 102mm. The SG-image AF 35mm f2.2 with a length of 36mm, is 66mm shorter. Besides being longer, the Leica APO-SL 50mm F2 ASPH also has a larger diameter of 73mm compared to the SG-image AF 35mm f2.2's 69mm 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. SG-image AF 35mm f2.2 weighs 163g, which means it is 577g (77%) lighter than the Leica APO-SL 50mm F2 ASPH which has a weight of 740g.
