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 A and the Samyang 14mm 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. Samyang 14mm F2.8 is the longer of the two lenses at 96mm. The Tamron 11-20mm F2.8 A with a length of 86mm, is 10mm shorter. Besides being longer, the Samyang 14mm F2.8 also has a larger diameter of 87mm compared to the Tamron 11-20mm F2.8 A'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 A weighs 335g, which means it is 217g (39%) lighter than the Samyang 14mm F2.8 which has a weight of 552g.
