The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Venus 8-15mm f2.8 and the Sigma 14mm F1.8 DG HSM Art 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 14mm F1.8 DG HSM Art is the longer of the two lenses at 126mm. The Venus 8-15mm f2.8 with a length of 76mm, is 50mm shorter. On the other hand, there is no difference between the max diameters of these lenses, both coming at 95mm.
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. Venus 8-15mm f2.8 weighs 650g, which means it is 520g (44%) lighter than the Sigma 14mm F1.8 DG HSM Art which has a weight of 1170g.
