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.
A high-performing lens for general photography.A superb general-purpose lens, Canon’s EF 24-105mm f/4 L IS USM is equally at home on the EOS 400D and the ‘full frame’ EOS 5D cameras, giving a focal length range equivalent to 38.4 to 168mm on the former. Compact for its specifications, it is relatively light and comfortable to use as well as being very well built. The lens barrel carries switches for IS (on/off) and AF/MF (Autofocus/Manual Focus). They are recessed into the lens barrel itself, which means you’re less likely to re-set them inadvertently.
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.
A high-performance ultra-wide-angle lens with remarkable flatness of field.Canon’s EF 14mm f/2.8L II USM lens replaces an existing lens with similar specifications. Designed for professional photographers and usable on both ‘full frame’ DSLRs and models with smaller (‘APS-C sized’) image sensors, it has many of the same specifications as the lens it replaces. However, it’s somewhat cheaper.
