The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Venus 12mm f2.8 MF and the Fujifilm XF 8-16mm F2.8 R LM WR 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. Fujifilm XF 8-16mm F2.8 R LM WR is the longer of the two lenses at 122mm. The Venus 12mm f2.8 MF with a length of 77mm, is 45mm shorter. Besides being longer, the Fujifilm XF 8-16mm F2.8 R LM WR also has a larger diameter of 88mm compared to the Venus 12mm f2.8 MF's 77mm 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. Venus 12mm f2.8 MF weighs 475g, which means it is 330g (40%) lighter than the Fujifilm XF 8-16mm F2.8 R LM WR which has a weight of 805g.
