Digital Camera World Verdict

Conveniently compact and lightweight for a full-frame compatible ultra-wide-angle zoom, this lens is also much more affordable than Canon’s previously launched 14-35mm and 15-35mm L-series RF-mount options. At just over 3.5 inches in length, the lens nevertheless packs a 5.5-stop optical image stabilizer and some up-market glass. Good build quality, handling and performance make it well worth the money, although it lacks weather-seals and the hood is sold separately.

The Canon RF 15-30mm F4.5-6.3 IS STM is an ultra-wide-angle zoom for ‘the rest of us’. The company already offers a brace of RF 14-35mm F4L IS USM and RF 15-35mm F2.8L USM but, as L-series lenses aimed at enthusiast and professional photographers with deep pockets, they’re much more expensive to buy. As the latest in the trio, the RF 15-30mm is much more affordable yet still delivers a mighty maximum viewing angle with a decent overall 2x zoom range, albeit with a relatively slow and variable aperture rating of f/4.5-6.3. 

The RF 14-35mm L-series lens is quite compact and lightweight for an ultra-wide zoom but the RF 15-30mm is particularly small for its type and a featherweight at just 390g. Designed with full-frame R-system cameras in mind, it’s also a good fit for APS-C format bodies including the EOS R7, R10 and R50, on which it has a still useful ‘effective’ zoom range of 24-48mm.
