The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 23mm F1.4 DC DN C and the Sigma 56mm F1.4 DC DN C 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 23mm F1.4 DC DN C is the longer of the two lenses at 77mm. The Sigma 56mm F1.4 DC DN C with a length of 60mm, is 17mm shorter. On the other hand, the Sigma 56mm F1.4 DC DN C has a larger diameter of 67mm compared to the Sigma 23mm F1.4 DC DN C's 66mm 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 56mm F1.4 DC DN C weighs 280g, 17% (60g) lighter than the Sigma 23mm F1.4 DC DN C's weight of 340g.
Filter Threads
The Sigma 23mm F1.4 DC DN C has a filter size of 52mm whereas the Sigma 56mm F1.4 DC DN C has a 55mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
