The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 15mm F4.5 and the Samyang 12mm 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. Samyang 12mm f2.0 is the longer of the two lenses at 59mm. The Voigtlander 15mm F4.5 with a length of 38mm, is 21mm shorter. Besides being longer, the Samyang 12mm f2.0 also has a larger diameter of 73mm compared to the Voigtlander 15mm F4.5's 59mm 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. Voigtlander 15mm F4.5 weighs 156g, which means it is 104g (40%) lighter than the Samyang 12mm f2.0 which has a weight of 260g.
