The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Tokina 12-24mm f4 DX II and the Sigma 12-24mm F4.5-5.6 II DG HSM 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. Sigma 12-24mm F4.5-5.6 II DG HSM is the longer of the two lenses at 120mm. The Tokina 12-24mm f4 DX II with a length of 90mm, is 30mm shorter.
