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 12-24mm f4 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 12-24mm f4 DX II is the longer of the two lenses at 90mm. The Canon 8-15mm f4L Fisheye USM with a length of 83mm, is 7mm shorter. Besides being longer, the Tokina 12-24mm f4 DX II also has a larger diameter of 84mm compared to the Canon 8-15mm f4L Fisheye USM's 79mm 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.
