Here’s our concise review of the Canon EF-S 10-18mm f/4.5-5.6 IS STM wide-angle zoom lens…
Canon’s ultra-wide entry for APS-C cameras is a hidden gem. Featuring a traditional landscape focal distance and slight 240g weight, it’s an ideal kit bag companion. The optics include 14 elements in 11 groups, and seven rounded diaphragm blades, though this is not a lens designed to capture bokeh. There’s a brace of switches on the barrel, which allow you to easily change between manual and autofocus, and engage 4-stop image stabilisation.
Considering the costs of this humble lens, the results are very impressive. As is typical for many zoom lenses, there is a touch of vignetting at f/4.5, and barrel distortion at 10mm, though it’s not overly pronounced, and very easy to correct in post-production. For the price, this lens displays excellent sharpness centrally throughout the range, though it’s a touch sharper at the 18mm end. Corners are also sharp when wide-open, and while not quite matching the central sharpness, the results are negligible.
