Excerpt: With the introduction of the Canon EF 70-300mm f/4-5.6 IS USM Lens, Canon has replaced one of its most popular lenses and its first image stabilized lens - the Canon EF 75-300mm f/4-5.6 IS . The 75-300mm IS lens was popular because of its useful focal length range, small size, light weight, midrange price and Image Stabilization . The 70-300 IS improves this overall package (sacrificing only price somewhat).
Excerpt: Despite being relatively light in weight, it felt robust in the hand and well-balanced on our EOS 60D body. The zoom extended smoothy and during testing, the AF performed quickly thanks to the built-in Ultrasonic Motor (USM), locking onto targets with no signs of hunting. It must be said though, that the motor on our sample did sound rather gritty and far from the ‘˜near silent' operation promised, which could be a potential turn-off for wildlifers as it risks disturbing...
Canon EF 70-300mm f/4-5.6 USM IS - APS-C Format Review / Retest
21 June 2009
Conclusion: The Canon EF 70-300mm f/4-5.6 USM IS is a very decent performer when used on an APS-C DSLR. It is capable of delivering very good results throughout the range. The peak performance is, of course, in the lower range but the results are still pretty impressive at 300mm. The amount of vignetting is minimal and distortions are nothing to worry about either.
Canon EF 70-300mm f/4-5.6 USM IS - Review / Test Report
7 June 2007
Conclusion: The performance of the Canon EF 70-300mm f/4-5.6 USM IS came as a total surprise. Unlike its predecessor the lens is capable to produce a very high performance throughout the zoom range without the significant drop in quality at 300mm typical for most consumer grade lenses in this range. It seems as if the new UD element helps to lift the optical quality significantly. Distortions, CAs as well as vignetting are also very respectable.
