The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 16mm F1.4 DC DN L and the Sigma 28mm F1.4 DG HSM A 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 28mm F1.4 DG HSM A is the longer of the two lenses at 108mm. The Sigma 16mm F1.4 DC DN L with a length of 92mm, is 16mm shorter. Besides being longer, the Sigma 28mm F1.4 DG HSM A also has a larger diameter of 83mm compared to the Sigma 16mm F1.4 DC DN L's 72mm 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 16mm F1.4 DC DN L weighs 405g, which means it is 555g (57%) lighter than the Sigma 28mm F1.4 DG HSM A which has a weight of 960g.
