Canon RF 28-70mm f/2L USM review

Quite a handful, this lens proves that mirrorless isn’t all about downsizing

Digital Camera World Verdict

It’s a fabulous lens that really can rival three or four separate prime lenses. Apart from lackluster corner-sharpness at 28mm, image quality is spectacular in all other respects. The sheer bulk and weight, however, feel a mismatch for a mirrorless body, leaving an f/2.8-sized gap in Canon’s RF line-up.

One of the main attractions of the Canon EOS R and EOS RP bodies is their comparatively compact and lightweight build, compared with full-frame DSLRs. Following suit, the Canon RF 24-105mm f/4L IS USM standard zoom lens shaves off 11mm in length and 95g in weight, compared with its EF L-series counterpart. 

By contrast, the Canon RF 28-70mm f/2 is a monster. It’s much bigger than it's EF opposite number, measuring 104x140mm, and about twice as heavy, at 1,430g. It’s also nearly twice the weight and twice the price of Canon’s top-spec EF 24-70mm f/2.8 lens, weighing about the same as a 70-200mm f/2.8 zoom.
