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.

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 ...

I believe I got mine in 2006 or 2007 and it has never disappointed. The f4 works for most outdoor use and it is a lens you can carry easily compared to the 2.8 with foot. The amazing quality really showed when I used it with my now retired film body, but also shows when my 17-85 is at telephoto and...

Amazing image quality and image stabilization

No weaknesses; Nicking it on price would not be fair because the big white Canon lenses are top tier and it seems like they spare nothing to make them

I own this lens which works perfectly. Good thing is that, you will get sharpest image while cropping the aberrant sides and corners of the frame. Image quality is simply awesome. 5 stars for that. !!

Its compact size and Light weight can be deceiving when put next to its bigger brother, But at its f4 aperture the performance of this lens is truly amazing the IS system works well Testing it i went as low as 1/13 shutter speed at 200mm with IS on and it kept on taking usable images ..

Easy to use; Compact; Build quality

The Canon EF 70-200mm f4 IS USM L lens is a professional grade 70-200mm lens without the size and heft, as well as price, as found in f2.8 versions.

Professional grade build quality, including dust and moisture sealing; four stops of image stabilization system; relatively lightweight

The tripod collar is optional; relatively expensive

You want a medium telephoto lens for your Canon dSLR, something with a constant aperture, solidly built with pro quality, yet light enough to carry on adventure to some faraway part of the world. You have looked at the f2.8 models but didn't think you could afford them or the Sherpa to carry them.
