The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica SL 35mm f2 ASPH and the Sigma 35mm F1.4 DG DN Art 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. Sigma 35mm F1.4 DG DN Art is the longer of the two lenses at 110mm. The Leica SL 35mm f2 ASPH with a length of 83mm, is 27mm shorter. Besides being longer, the Sigma 35mm F1.4 DG DN Art also has a larger diameter of 76mm compared to the Leica SL 35mm f2 ASPH's 75mm 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 35mm f2 ASPH weighs 400g, which means it is 245g (37%) lighter than the Sigma 35mm F1.4 DG DN Art which has a weight of 645g.
