The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica SL 21mm F2 ASPH and the Leica 16-35mm F3.5-4.5 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 16-35mm F3.5-4.5 ASPH is the longer of the two lenses at 238mm. The Leica SL 21mm F2 ASPH with a length of 102mm, is 136mm shorter. Besides being longer, the Leica 16-35mm F3.5-4.5 ASPH also has a larger diameter of 88mm compared to the Leica SL 21mm F2 ASPH's 73mm 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 SL 21mm F2 ASPH weighs 789g, which means it is 201g (20%) lighter than the Leica 16-35mm F3.5-4.5 ASPH which has a weight of 990g.
