The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon 24mm F2.8 STM and the Canon TS-E 17mm f4L 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 TS-E 17mm f4L is the longer of the two lenses at 107mm. The Canon 24mm F2.8 STM with a length of 23mm, is 84mm shorter. Besides being longer, the Canon TS-E 17mm f4L also has a larger diameter of 89mm compared to the Canon 24mm F2.8 STM's 68mm 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 24mm F2.8 STM weighs 125g, which means it is 695g (84%) lighter than the Canon TS-E 17mm f4L which has a weight of 820g.
Lens Mounts
The Canon 24mm F2.8 STM has the Canon EF-S lens mount whereas the Canon TS-E 17mm f4L has the Canon EF lens mount. Some of the latest released cameras that are compatible with these mounts are Canon T8i, Canon 90D and Canon SL3 for the Canon EF-S Mount and Blackmagic URSA 12K LF, Z CAM E2-F6 II 6K and Z CAM E2-S6 II 6K for the Canon EF Mount.
Focal Range
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.
On the other hand, the Canon TS-E 17mm f4L is a prime lens with fixed focal lenght of 17mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of 27.2mm.
