The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 16-28mm F2.8 L and the Canon 16-35mm f2.8L II USM 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. Canon 16-35mm f2.8L II USM is the longer of the two lenses at 112mm. The Sigma 16-28mm F2.8 L with a length of 101mm, is 11mm shorter. Besides being longer, the Canon 16-35mm f2.8L II USM also has a larger diameter of 89mm compared to the Sigma 16-28mm F2.8 L's 77mm 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. Sigma 16-28mm F2.8 L weighs 450g, which means it is 185g (29%) lighter than the Canon 16-35mm f2.8L II USM which has a weight of 635g.
Filter Threads
The Sigma 16-28mm F2.8 L has a filter size of 72mm whereas the Canon 16-35mm f2.8L II USM has a 82mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 72mm filters that we recommend you to consider for the Sigma 16-28mm F2.8 L:
And these are the 82mm filters that we recommend for the Canon 16-35mm f2.8L II USM:
