The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Tokina atx-i Pro 11-16mm F2.8 CF and the Canon 10-18mm f4.5-5.6 IS STM 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. Tokina atx-i Pro 11-16mm F2.8 CF is the longer of the two lenses at 89mm. The Canon 10-18mm f4.5-5.6 IS STM with a length of 72mm, is 17mm shorter. Besides being longer, the Tokina atx-i Pro 11-16mm F2.8 CF also has a larger diameter of 84mm compared to the Canon 10-18mm f4.5-5.6 IS STM'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. Canon 10-18mm f4.5-5.6 IS STM weighs 240g, 56% (315g) lighter than the Tokina atx-i Pro 11-16mm F2.8 CF's weight of 555g.
