The Canon EF 70-200mm f/4L IS USM ($1,349 direct) isn't as lauded as the company's f/2.8 IS lens with the same zoom range, but it's priced about $650 less, making it an attractive option for shooters who can live with a slower lens.

The Canon EF 70-200mm f/4L IS USM ($1,349 direct)($1,199.00 at Amazon) isn't as lauded as the company's f/2.8 IS lens with the same zoom range, but it's priced about $650 less, making it an attractive option for shooters who can live with a slower lens. It is similar in design and price to the Nikon AF-S 70-200mm f/4G ED VR($1,396.95 at Amazon) lens. It's compatible with full-frame Canon cameras, and can also be used with APS-C bodies, where it acts more like a 112-320mm lens due to the 1.6x crop factor. It's very sharp across the frame at its widest focal length, but performance at the edges suffers when set to 200mm. Like other Canon L zooms, the lens features a white finish rather than a traditional black. It measures 6.8 by 3 inches (HD) and weighs 1.7 pounds. A hood is included, but not a tripod collar. Adding one helps to better distribute weight when used with a tripod and adds $210 to the cost. It supports 67mm filters and can focus on objects as close as 3.9 feet; that's ...

This is a fantastic lens! Possibly the best value in the Canon line. Quick accurate focus with beautiful results. It is f/4 so one has to understand limitations vs what a f/2.8 version may deliver, still I am able to achieve excellent images in challenging light with my 6D.

Canon EF 70-200mm f/4L IS USM is the latest addition to Canon's range of 70-200mm telephoto zooms and fills in the whole in Canon's lineup previously consisting of two faster f/2.8 variants (EF 70-200mm f/2.8L IS USM and EF 70-200mm f/2.8L USM) and another f/4 version (EF 70-200mm f/4L USM).

Gary Wolstenholme takes a look at how this compact telephoto zoom lens performs. Canon's EF 70-200mm f/4L IS USM costs around ￡800 and has an Image Stabiliser, silent Ultrasonic focusing with full time manual override and is sealed against dust and moisture.

The EF50/1.2L is a totally new optical design (there was an old FD 50/1.2L) and uses a molded aspheric rear element (the 50/1.0L used two very expensive ground and polished aspherics). It has a true ring type USM motor and a high speed CPU for fast focus.
