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 105mm F2.8 DG DN Macro 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 105mm F2.8 DG DN Macro is the longer of the two lenses at 134mm. The Kase 85mm F1.4 with a length of 99mm, is 35mm shorter. On the other hand, the Kase 85mm F1.4 has a larger diameter of 82mm compared to the Sigma 105mm F2.8 DG DN Macro's 74mm diameter.
