The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Kase 85mm F1.4 and the Sigma 200mm F2 DG 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 200mm F2 DG is the longer of the two lenses at 201mm. The Kase 85mm F1.4 with a length of 99mm, is 102mm shorter. Besides being longer, the Sigma 200mm F2 DG also has a larger diameter of 119mm compared to the Kase 85mm F1.4's 82mm diameter.
Below you can find a scaled side-by-side image of Kase 85mm F1.4 and Sigma 200mm F2 DG to get a better idea of how their sizes compare in real life.
Comparison image of the Kase 85mm F1.4 and the Sigma 200mm F2 DG Size and Weight 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. Kase 85mm F1.4 weighs 580g, which means it is 1240g (68%) lighter than the Sigma 200mm F2 DG which has a weight of 1820g.
