The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon 8-15mm f4L Fisheye USM and the Tokina 11-16mm f2.8 DX II 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 11-16mm f2.8 DX II is the longer of the two lenses at 89mm. The Canon 8-15mm f4L Fisheye USM with a length of 83mm, is 6mm shorter.
