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

8.5 Rating

A first-rate wide-angle zoom for DSLRs with ‘APS-C’ sized imagers.The ‘EF-S’ designation is Canon’s way of labelling lenses with Short Back Focus, which indicates the distance between the sensor plane and the rear element of the lens is shorter than in an EF lens. Such lenses are designed exclusively for EOS cameras with ‘APS-C-sized’ sensors and cannot be used on Canon’s 35mm SLR cameras – or on the EOS 5D. The new EF-S 10-22mm ultra-wide-angle zoom lens covers fields of view equivalent to 16-35mm in 135mm format. An excellent partner to the EOS 400D we used for our tests, its wide angle of view is great for landscape and architectural photography, especially indoor shots.

A compact, high-magnification zoom lens with few aberrations and effective image stabilisation.The EF 70-300mm f/4.5-5.6 DO IS USM is Canon’s second lens with three-layer type Diffractive Optics (DO). It can be used with both ‘APS-C’ (where it covers angles of view equivalent to 112mm to 480mm) and 35mm-sized image sensors. Using three layers of diffraction gratings enables lens designers to almost completely cancel out chromatic aberration and subdue spherical aberration to a near-negligible point. The resulting lenses are smaller and lighter and can out-perform other zoom lenses with equivalent focal lengths and aperture ranges that use fluorite, ED or aspherical glass elements to controls these aberrations.

Canon EF 70-200mm f/2.8L IS USM Lens

A high-quality, fast medium-range zoom lens that will suit fashion, wedding and portrait photographers.Built like a tank and ultra-responsive, Canon’s EF 70-200mm f/2.8L USM lens is a great tool for fashion, wedding, portrait and event photographers and a good match for full frame DSLRs like the EOS-1Ds Mark II and EOS 5D. The addition of Canon’s second-generation image stabilisation technology adds $1,180 to its price tag but gives photographers up to three stops of exposure compensation, which is useful when flash is not permitted.
