The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 16mm F1.4 DC DN MFT and the Samyang 16mm f2.0 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 16mm F1.4 DC DN MFT is the longer of the two lenses at 92mm. The Samyang 16mm f2.0 with a length of 89mm, is 3mm shorter. On the other hand, the Samyang 16mm f2.0 has a larger diameter of 83mm compared to the Sigma 16mm F1.4 DC DN MFT's 72mm 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. Sigma 16mm F1.4 DC DN MFT weighs 405g, which means it is 178g (30%) lighter than the Samyang 16mm f2.0 which has a weight of 583g.
