Canon RF 24-105mm f/4L IS USM Review

October 10, 2018 | Mark Goldstein | Rating star Rating star Rating star Rating star Half rating star


The Canon RF 24-105mm f/4L IS USM is an excellent standard zoom lens that optically is a step above the equivalent DSLR variant, the Canon EF 24-105mm f/4L IS II USM, which incidentally is one of Canon's most popular lenses.

The RF 24-105mm offers a very versatile focal range whilst being tack-sharp from 24mm to 85mm, both in the centre and at the edges of the frame. Sharpness at the far end of the telephoto range isn't quite as good when shooting wide-open at f/4, but you only have to stop down to f/5.6 to get more than acceptable results. Overall the Canon RF 24-105mm f/4L IS USM delivers excellent sharpness across the frame at most apertures. Vignetting at wide-open apertures and some barrel distortion at 24mm are the only other real optical issues of note.

Build quality is excellent, certainly up to the usual L-lens standard, with the built-in weather-proofing offering peace of mind in more inclement conditions. Canon also provide a very good lens hood and padded case in the box. Auto-focusing proved to be extremely quick, quiet and reliable on the Canon EOS R camera body that we tested the lens with, while manual focus over-ride at any time is a great feature, as is the very effective 5-stop optical image stabilisation system. The new Lens Control Ring, making its debut on this lens, takes a little getting used to, but soon becomes quite a handy feature to have.

The standalone price of the Canon RF 24-105mm f/4L IS USM isn't quite so attractive, although we suspect that most sales will be with the EOS R body as its kit lens. Despite the price-tag, we can still strongly recommend the new Canon RF 24-105mm f/4L IS USM as a solidly built, versatile standard zoom lens that delivers superb image quality.
