The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon EF 50mm f/1.8 STM and the Sigma 24-105mm F4 DG OS HSM 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 24-105mm F4 DG OS HSM is the longer of the two lenses at 109mm. The Canon EF 50mm f/1.8 STM with a length of 39mm, is 70mm shorter. Besides being longer, the Sigma 24-105mm F4 DG OS HSM also has a larger diameter of 89mm compared to the Canon EF 50mm f/1.8 STM's 69mm 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 50mm f/1.8 STM weighs 159g, which means it is 726g (82%) lighter than the Sigma 24-105mm F4 DG OS HSM which has a weight of 885g.
Filter Threads
The Canon EF 50mm f/1.8 STM has a filter size of 49mm whereas the Sigma 24-105mm F4 DG OS HSM has a 82mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 49mm filters that we recommend you to consider for the Canon EF 50mm f/1.8 STM:
And these are the 82mm filters that we recommend for the Sigma 24-105mm F4 DG OS HSM:
Lens Mounts
Both the Canon EF 50mm f/1.8 STM and the Sigma 24-105mm F4 DG OS HSM has the same Canon EF lens mount. Some of the latest released cameras that are compatible with the Canon EF lenses are Blackmagic URSA 12K LF, Z CAM E2-F6 II 6K and Z CAM E2-S6 II 6K.
Sigma 24-105mm F4 DG OS HSM is also available in Nikon F (FX) , Sony Alpha and Sigma SA mounts.
