Canon 24mm f/2.8 EF-S STM (9522B005)

For its ultra-compact dimensions and light weight, the Canon EF-S 24mm f / 2.8 STM lens has earned the honor of being called a “pancake” — this is the name of optics with extremely small body dimensions in length (in this case, about 7 cm).

Under the crop

The model name contains the symbols EF-S, hinting at the compatibility of the lens exclusively with Canon cropped DSLRs. For installation on full-frame “carcasses”, the “pancake” Canon EF 40mm f / 2.8 STM is more suitable. Its 24-mm prime repeats both in size and focal length — given that the crop factor of Canon APS-C DSLRs is 1.6x, shooting paired with a lens is performed at almost the same focal length as its full-frame counterpart (38 mm in 35 mm equivalent).

Autofocus drive

Despite the miniature form factor, in the body of the lens there was a place not only for the elements of the optical design, but also for the quiet STM autofocus stepping motor, focus quickly, accurately and accurately in most situations. The photographer also has the right to aim at the subject manually, for which you need to switch the “AF / MF” slider on the lens body to the desired position and use the services of the focus ring at the front lens. Due to the modest dimensions of the Canon EF-S 24mm f/2.8 STM, the ring on its body is very narrow, which may seem inconvenient for some.

The nature of the drawing

The lens provides a high level of image sharpness starting from the widest aperture (f / 2.8). Up to f / 5.6, sharpness only increases, and then gradually declines. Not everything is so smooth, only with vignetting at the widest aperture and the presence of slight barrel-shaped distortions in the pictures. Both of these problems are corrected when post-processing the footage in a photo editor in just a couple of mouse clicks. The compact dimensions of the lens, combined with high image quality, make it possible to recommend it as a solution that you can take with you anywhere — a fix does not take up much space, and it will always help to get the required frame.
