The type of photography that you are planning to use is an important decision factor. Here we have evaluated the 7artisans 10mm f2.8 II RF and the Tamron 11-20mm F2.8 RF 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. 7artisans 10mm f2.8 II RF is the longer of the two lenses at 95mm. The Tamron 11-20mm F2.8 RF with a length of 84mm, is 11mm shorter. Besides being longer, the 7artisans 10mm f2.8 II RF also has a larger diameter of 75mm compared to the Tamron 11-20mm F2.8 RF'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 RF weighs 340g, 43% (262g) lighter than the 7artisans 10mm f2.8 II RF's weight of 602g.
