Offering the 35mm equivalent of 16-35mm, this Canon lens covers pretty much every useful and popular wideangle focal length, in a reasonably lightweight, yet sturdy package. The lens weighs just 385g, and has Canon’s Ultrasonic Motor for fast, whisper-quiet autofocusing.

The optical construction consists of thirteen elements in ten groups and includes three aspherical elements and a Super-UD element. Super-UD is Canon’s ultra low-dispersion glass to aid in the correction of chromatic aberration.

Canon also allows the lens to focus down to 24cm, which is great for including foreground interest, especially when combined with deep depth of field focusing. Unfortunately, Canon loses some brownie points by not including a lens hood, so factor another £25 into your budget.

While this isn’t one of Canon’s professional L-series lenses, the construction is impressive, with a solid metal lens mount and robust materials. The zoom ring is loose without being slack, and rotates smoothly. Similarly the manual focus ring is solid and smooth. Incidentally the focus offers manual focus in AF mode, which is ideal for fine-tuning focusing if the camera AF misses the spot. The AF speed is impressive and the operation certainly very quiet.

Image Quality
In field trials the Canon 10-22mm is a very capable performer, displaying fantastic contrast and sharpness. All’s not perfect, though: there’s signs of fringing, especially towards the image corners, though also in some high-contrast areas in the centre of the frame. At wider apertures, sharpness can fall off fairly quickly, again with the corners of the frame suffering the most, and some detail goes positively mushy.

On the bench, the Canon produces good results, with best perofrmance at f/8. Sadly it suffers from high chromatic aberration (CA), especially at 10mm and at the edges. Distortion at 10mm is also quite pronounced.


This is a reasonable performer, but not best in the class, with disappointing results, especially with regard to edge and corner performance.
