Canon EF-S 10-22mm F/3.5-4.5 USM SLR Lens

Classified as a midrange zoom lens, the Canon EF 10 22mm f/3.5-4.5 USM SLR Lens has very good image quality as it contains Super UD and three aspherical lens elements. Despite its excellent qualities it doesn’t quite cut the mustard to be an L series lens. It weighs about 385g with a maximum length of 90mm, a maximum diameter of 83mm, and a filter diameter of 77mm. In terms of distortion levels this lens actually out performs both the 17-40mm and 16-35mm L series lenses and is considered the be one of the best wide angle lenses offered by Canon. Barrel distortions or the presence of soft corners in photos with this lens are either minimized or eradicated altogether. This lens is not perfect however, there have been reports of small pincusions accruing at 22mm and barrel distortions at around 10mm.

At only 22 mm the Canon 10 22 mm ef s f/3.5-4.5 USM SLR Lens can deliver the same framing as a general zoom lens at its largest focal length. Vignetting appears at wide open apertures or 10mm focal length but can be addressed by increasing focal length or narrowing down the aperture. Since wide angle lenses try to fit everything into a frame, details are usually lost along the way. This lens however even over the entire focal length range and down to the corners of the frame delivers a very sharp image. Stopping down can also improve the sharpness further. During bright outdoor settings the lens can control flare very well.

Another great thing about the Canon EF S 10 22mm f/3.5-4.5 USM SLR Lens is that it provides its users with a very deep depth of field. It suits users who are into bokeh or who would like to add that dramatic blur in the background of their shots. Focusing is fast and noiseless thanks to the Ultrasonic Motor (USM) that is uses, not to mention a short infinity focus distance too. Handheld photo taking is made easier and slightly convenient with its maximum aperture of about 3.5 to 4.5 and wide focal lengths.

The Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens is great of great use when doing architectural or interior design photography. Using it on close-up portraits however will yield very dramatic and bent images unless this is the effect the user desires. Of course its most common use would be for wide environmental portraits or scenic landscapes as the angle of view takes in a lot of background.
