The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica SL 100-400 f5-6.3 and the Sigma 60-600mm F4.5-6.3 DG DN 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 60-600mm F4.5-6.3 DG DN is the longer of the two lenses at 279mm. The Leica SL 100-400 f5-6.3 with a length of 198mm, is 81mm shorter. Besides being longer, the Sigma 60-600mm F4.5-6.3 DG DN also has a larger diameter of 119mm compared to the Leica SL 100-400 f5-6.3's 88mm diameter.
