The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sirui 35mm F1.4 and the Leica APO-SL 28mm 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 28mm F2 ASPH is the longer of the two lenses at 102mm. The Sirui 35mm F1.4 with a length of 101mm, is 1mm shorter. On the other hand, the Sirui 35mm F1.4 has a larger diameter of 76mm compared to the Leica APO-SL 28mm 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. Sirui 35mm F1.4 weighs 494g, which means it is 206g (29%) lighter than the Leica APO-SL 28mm F2 ASPH which has a weight of 700g.
