The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 23mm F1.4 C and the Sigma 16mm F1.4 DC DN E 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 16mm F1.4 DC DN E is the longer of the two lenses at 92mm. The Sigma 23mm F1.4 C with a length of 79mm, is 13mm shorter. Besides being longer, the Sigma 16mm F1.4 DC DN E also has a larger diameter of 72mm compared to the Sigma 23mm F1.4 C's 66mm diameter.
Below you can find a scaled side-by-side image of Sigma 23mm F1.4 C and Sigma 16mm F1.4 DC DN E to get a better idea of how their sizes compare in real life.
Comparison image of the Sigma 23mm F1.4 C and the Sigma 16mm F1.4 DC DN E Size and Weight 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 23mm F1.4 C weighs 330g, which means it is 75g (18%) lighter than the Sigma 16mm F1.4 DC DN E which has a weight of 405g.
Filter Threads
The Sigma 23mm F1.4 C has a filter size of 52mm whereas the Sigma 16mm F1.4 DC DN E has a 67mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
