The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Tamron 11-20mm F2.8 X and the Samyang 10mm f2.8 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. Tamron 11-20mm F2.8 X is the longer of the two lenses at 86mm. The Samyang 10mm f2.8 with a length of 77mm, is 9mm shorter. On the other hand, the Samyang 10mm f2.8 has a larger diameter of 86mm compared to the Tamron 11-20mm F2.8 X's 73mm 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. Tamron 11-20mm F2.8 X weighs 335g, which means it is 245g (42%) lighter than the Samyang 10mm f2.8 which has a weight of 580g.
