Canon EF-S 24mm f/2.8 STM

The Canon EF-S 24mm f/2.8 STM is a slimline lens, with a slender manual focus ring and focus mode switch being the only controls

The slender frame of this 24mm f/2.8 lens conceals an optical construction of six elements in five groups, including an aspherical element to minimise distortion. It may be tempting to ask how it’s possible to fit all this glass into the available space, but the optical unit is, in fact, larger than it appears. This is because the lens takes advantage of the short back-focus afforded by the EF-S mount, with the rear element protruding beyond the back of the mount, protected by a plastic surround.

With seven rounded blades, the aperture is adjustable from f/2.8 down to a minimum of f/22. The filter thread is 52mm, and does not rotate on focusing, which is always welcome for filter users. Due to the slimline design there’s no bayonet mount for a lens hood – you have to use a screw-in one instead, such as the Canon ES-52. One other thing that is missing – which is understandable given the dimensions – is optical image stabilisation.
