The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Tamron 10-24mm f3.5-4.5 II LD and the Sony 16mm F2.8 Fisheye 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 10-24mm f3.5-4.5 II LD is the longer of the two lenses at 84mm. The Sony 16mm F2.8 Fisheye with a length of 67mm, is 17mm shorter. Besides being longer, the Tamron 10-24mm f3.5-4.5 II LD also has a larger diameter of 83mm compared to the Sony 16mm F2.8 Fisheye's 75mm 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. Sony 16mm F2.8 Fisheye weighs 400g, 1% (6g) lighter than the Tamron 10-24mm f3.5-4.5 II LD's weight of 406g.
