Why We Like the Canon RF16mm F2.8 STM

The biggest selling point is its combination of an ultra-wide perspective, bright f/2.8 aperture, and affordable price. The lens offers an aperture range of f/2.8 to f/22, giving photographers flexibility over exposure and depth of field. Its seven-blade aperture diaphragm can also produce pleasing background blur, although the ultra-wide focal length makes pronounced subject separation more challenging than with longer lenses.

Weighing just 165g and measuring approximately 40.2mm long, the RF16mm F2.8 STM is exceptionally portable. You can leave it mounted on your camera throughout the day without adding much weight to your setup. Canon uses a gear-type stepping motor (STM) for autofocus, providing quiet and smooth focusing. Subject recognition and tracking for people, animals, vehicles, and other subjects depend on the capabilities of the EOS R camera body rather than the lens itself.

The lens also offers a minimum focusing distance of just 13cm and a maximum magnification of 0.26x. This allows you to get relatively close to your subjects while retaining the expansive perspective of an ultra-wide lens. It’s a useful combination for creative close-up photography, especially when you want to include plenty of the surrounding environment.

What to Consider Before Buying

The RF16mm F2.8 STM isn’t weather-sealed, so you’ll need to be careful when shooting in heavy rain, dusty environments, or other challenging conditions. Canon also doesn’t include a lens hood in the standard package, meaning you’ll need to purchase one separately if you want additional protection against stray light and accidental bumps.

Keep in mind that 16mm is an ultra-wide focal length, which can introduce noticeable perspective distortion, particularly when photographing people near the edges of the frame. The lens is also a prime, so you’ll need to move around to adjust your composition rather than relying on a zoom ring. Still, at $259, it’s an affordable way to expand your Canon RF kit with a lightweight ultra-wide option.
