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 Canon EF-M 32mm F1.4 STM 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 Canon EF-M 32mm F1.4 STM with a length of 57mm, is 3mm shorter. Besides being longer, the Sigma 56mm F1.4 DC DN C also has a larger diameter of 67mm compared to the Canon EF-M 32mm F1.4 STM'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. Canon EF-M 32mm F1.4 STM weighs 235g, 16% (45g) 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 Canon EF-M 32mm F1.4 STM has a 43mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 55mm filters that we recommend you to consider for the Sigma 56mm F1.4 DC DN C:
And these are the 43mm filters that we recommend for the Canon EF-M 32mm F1.4 STM:
Lens Mounts
The Sigma 56mm F1.4 DC DN C has the Sony E lens mount whereas the Canon EF-M 32mm F1.4 STM has the Canon EF-M lens mount. Some of the latest released cameras that are compatible with these mounts are Sony A6700, Sony FX30 and Sony ZV-E10 for the Sony E Mount and Canon M50 II, Canon M200 and Canon M6 MII for the Canon EF-M Mount.
Sigma 56mm F1.4 DC DN C is also available in Micro Four Thirds and Leica L mounts.
