The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon 24-105mm F3.5-5.6 IS STM and the Sigma 30mm F1.4 DC 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. Canon 24-105mm F3.5-5.6 IS STM is the longer of the two lenses at 104mm. The Sigma 30mm F1.4 DC HSM with a length of 63mm, is 41mm shorter. Besides being longer, the Canon 24-105mm F3.5-5.6 IS STM also has a larger diameter of 83mm compared to the Sigma 30mm F1.4 DC HSM's 74mm 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 30mm F1.4 DC HSM weighs 435g, 17% (90g) lighter than the Canon 24-105mm F3.5-5.6 IS STM's weight of 525g.
Filter Threads
The Canon 24-105mm F3.5-5.6 IS STM has a filter size of 77mm whereas the Sigma 30mm F1.4 DC HSM has a 62mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 77mm filters that we recommend you to consider for the Canon 24-105mm F3.5-5.6 IS STM:
And these are the 62mm filters that we recommend for the Sigma 30mm F1.4 DC HSM:
Lens Mounts
Both the Canon 24-105mm F3.5-5.6 IS STM and the Sigma 30mm F1.4 DC 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 30mm F1.4 DC HSM is also available in Nikon F (DX) and Sigma SA mounts.
Focal Range
Canon 24-105mm F3.5-5.6 IS STM has a focal range of 24-105mm and
4.4X zoom ratio . When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of
38.4 - 168mm.
On the other hand, the Sigma 30mm F1.4 DC HSM is a prime lens with fixed focal lenght of 30mm which has an effective (full-frame 35mm equivalent) focal range of 48mm when used on a APS-C / DX format camera.
