The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 56mm F1.4 DC DN C and the Sigma 60mm F2.8 DN 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 56mm F1.4 DC DN C is the longer of the two lenses at 60mm. The Sigma 60mm F2.8 DN with a length of 56mm, is 4mm shorter. Besides being longer, the Sigma 56mm F1.4 DC DN C also has a larger diameter of 67mm compared to the Sigma 60mm F2.8 DN's 61mm 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 60mm F2.8 DN weighs 190g, 32% (90g) lighter than the Sigma 56mm F1.4 DC DN C's weight of 280g.
Filter Threads
The Sigma 56mm F1.4 DC DN C has a filter size of 55mm whereas the Sigma 60mm F2.8 DN has a 46mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
