The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 24-35mm F2 DG HSM A and the Canon 24mm F2.8 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 24-35mm F2 DG HSM A is the longer of the two lenses at 123mm. The Canon 24mm F2.8 STM with a length of 23mm, is 100mm shorter. Besides being longer, the Sigma 24-35mm F2 DG HSM A also has a larger diameter of 88mm compared to the Canon 24mm F2.8 STM's 68mm diameter.
Below you can find a scaled side-by-side image of Sigma 24-35mm F2 DG HSM A and Canon 24mm F2.8 STM to get a better idea of how their sizes compare in real life.
Comparison image of the Sigma 24-35mm F2 DG HSM A and the Canon 24mm F2.8 STM Size and Weight 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 24mm F2.8 STM weighs 125g, 86% (816g) lighter than the Sigma 24-35mm F2 DG HSM A's weight of 941g.
Filter Threads
The Sigma 24-35mm F2 DG HSM A has a filter size of 82mm whereas the Canon 24mm F2.8 STM has a 52mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 82mm filters that we recommend you to consider for the Sigma 24-35mm F2 DG HSM A:
And these are the 52mm filters that we recommend for the Canon 24mm F2.8 STM:
Lens Mounts
The Sigma 24-35mm F2 DG HSM A has the Canon EF lens mount whereas the Canon 24mm F2.8 STM has the Canon EF-S lens mount . Some of the latest released cameras that are compatible with these mounts are Blackmagic URSA 12K LF , Z CAM E2-F6 II 6K and Z CAM E2-S6 II 6K for the Canon EF Mount and Canon T8i , Canon 90D and Canon SL3 for the Canon EF-S Mount.
Nikon F (FX) and Sigma SA mounts.
Focal Range
Sigma 24-35mm F2 DG HSM A has a focal range of 24-35mm and
1.5X 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 - 56mm .
On the other hand, the Canon 24mm F2.8 STM is a prime lens with fixed focal lenght of 24mm which has an effective (full-frame 35mm equivalent) focal range of 38.4mm when used on a APS-C / DX format camera.
