Photo.net Reviews Canon EF70-300mm DO IS Lens
Luminous Landscape have reviewed Canon’s new EF70-300mm f/4.5-5.6 DO IS USM telephoto zoom lens, which measures less than 10cm long and includes Canon’s Image Stabilisation technology to reduce camera shake.
“Would I recommend the 70-300 DO? It is probably not for most people, especially at the price. Here in the UK it sells for ?1,049. Canon have to recover the R+D costs of diffractive optics so early products will carry a premium price. They see the technology coming to cheaper lenses eventually, allowing shorter low-cost lenses to be produced. The cost of moulding diffractive elements, if mass-produced, is said not to be inherently high.”
