The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox 26mm f2.8 FE and the Sigma 35mm F2 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 35mm F2 DG DN is the longer of the two lenses at 65mm. The Viltrox 26mm f2.8 FE with a length of 24mm, is 41mm shorter. Besides being longer, the Sigma 35mm F2 DG DN also has a larger diameter of 70mm compared to the Viltrox 26mm f2.8 FE's 66mm 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. Viltrox 26mm f2.8 FE weighs 130g, which means it is 195g (60%) lighter than the Sigma 35mm F2 DG DN which has a weight of 325g.
