W e’ve reviewed the Canon EF-M 22mm f/2 STM pancake lens in this Super Test but, if you’ve got an EOS M-series camera, the chances are you’ve got the Canon EF-M 15-45mm f/3.5-6.3 IS STM zoom lens as well. This lens is usually sold as a kit lens with EOS M bodies and, if you prefer a zoom to a prime for your all-day shooting, it’s unbeatable.
The lens is unfeasibly compact and lightweight, with a crafty retractable design that shrinks it to just 61x45mm for stowing away, and it tips the scales at just 130g. Even so, it has a useful ‘effective’ zoom range of 24-72mm in full-frame terms, and packs an effective 3.5-stop optical IS. Corner-to-corner sharpness could be better but, overall, it’s a solid performer and a joy to use.
