Canon raises the stakes for professional photography with its EF 70-300mm f/4.5-5.6 DO IS USM telephoto lens with image stabilization. Thanks to a new triple-layered diffractive optical element (DO), this 70-300mm lens is less than 4 inches (10 cm) long. It can focus down to 4.6 feet (without rotating the front element) and a new zoom lock button keeps the lens safe and secure when not in use or used at the wide angle. A virtually silent ultra-sonic motor (USM) gives the lens extremely fast autofocus. The lens also includes Canon’s Image Stabilization technology to dramatically reduce camera shake, compensating for approximately three stops in shutter speed without any perceptible increase in image blur. It’s a great choice for professional photojournalists and serious advanced amateurs who need to contain the size and weight of equipment carried.

Update on Zoom Reduction (sep 02, 2011)
Since I wrote about eliminating my zoom lenses, I’ve used my Canon 70-300mm f/4.5-5.6 DO IS USM zoom lens only three times. Of those photos, I’ve only used five of the photos I took with it.
Reducing Zoom (jul 18, 2010)
In my collection of Canon EF lenses, I have a Canon EF 70-300mm f/4.5-5.6 DO IS USM lens. It’s an excellent lens. I don’t think there’s any other lens in this range of zoom lenses that’s better than it for Canon EOS cameras.
