The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Tokina 11-16mm f2.8 DX and the Canon 16-35mm f2.8L USM for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is an important deciding factor when comparing two lenses. Canon 16-35mm f2.8L USM is the longer of the two lenses at 103mm.
