Summary

The Canon RF 24-240mm f4-6.3 IS USM is the first super-zoom lens for Canon’s full-frame EOS R mirrorless system. It sports the longest zoom range in the system so far while also becoming one of the more affordable models to date. Both make it an ideal ‘kit-zoom’ for the lower cost bodies like the EOS RP. It employs Nano USM focusing, has a control ring that’s switchable between manual focus and custom adjustments, and optical stabilisation good for five stops. The RF 24-240mm looks set to become a very popular general-purpose lens for EOS R owners, especially the RP, and it’s the lens this body was crying out for when launched a few months earlier.

Canon RF 24-240mm f4-6.3 IS USM review – preview

The Canon RF 24-240mm f4-6.3 IS USM is a super-zoom lens for Canon’s full-frame EOS R mirrorless system. One of six new RF lenses released in 2019, it sports the longest zoom range in the system so far, while also becoming one of the more affordable models to date. Both make it an ideal all-round lens and the perfect ‘kit-zoom’ for the lower cost bodies in the system like the EOS RP.

The lens weighs 750g and measures 80mm in diameter with a 72mm filter thread, and is 123mm long, although understandably extends a fair amount when zoomed-in; sadly it’s not sealed against dust and moisture. The optical design consists of 21 elements in 15 groups, has seven diaphragm blades, a closest focusing distance of 50cm at the wide end or 78cm at the long end, and thankfully features optical stabilisation which Canon claims is good for five stops. Focusing is performed by a Nano USM motor. The variable f4-6.3 aperture begins to slow down to f4.5 at 27mm, then to f5 at 44mm, losing a full stop to f5.6 at 70mm, before reaching its minimum value of f6.3 between 109 to 240mm.

Like all RF lenses to date, it includes a custom control ring, although becomes the first that performs double-duty as a manual focusing ring, with a switch on the barrel to select between the two. Slightly odd as I assumed all RF lenses would feature a dedicated control ring in addition to manual focus. That said, the target market will probably mostly use the lens in autofocus. I had a very brief chance to try it out at an official Canon press event and you can watch the highlights in my first-looks video below.
