This zoom lens' AF response is also very fast and the use of the Micro USM provides a near-silent AF focusing. In any case, if you need to resort to using manual focus, the focusing ring (photo, above) is provided with a wider grip as compared to other EF lenses, including those Ring USM types utilizing the FT-M (Full Time-Manual) feature. View at the 75mm focal length View at the 100mm focal length View at the 135mm focal length View at the 200mm focal length View at the 300mm focal length   Like its Micro Motor counterpart, the EF 75-300mm f/4-5.6 III USM is so compact that users of entry-level models like the Canon EOS 888, EOS 88, EOS 500N and the EOS 300 will find this zoom a suitable choice when it comes to buying another lens to complement their standard EF 28-80mm or EF 35-80mm lenses. This zoom lens will also not hurt their necks or shoulders when left dangling or fitted to any entry-level EOS model compared to heavier lenses like the EF 70-200mm f/2.8L USM and EF 100-400mm f/4.5-5.6L IS USM. << Back to Main . 1 . 2 . 3 . 4 .
