Excerpt: Perhaps the most versatile of all moderate tele zoom focal lengths, the 70-200mm or thereabouts range is a hallmark and standard-bearer for many optical companies. Being a constant aperture (fast) zoom, this lens opens up numerous focusing, depth of field and perhaps as important low light shooting...
Summary: Canon's update to its professional fast telezoom may look much the same on the outside, but internally it's been updated to give image quality that's quite simply the best in its class. Effective autofocus and image stabilization systems, plus full weather sealing, round off a compelling package.
Pros: Exceptional image quality, Superb build quality, including dust- and water-sealing, Highly effective image stabilization, Excellent autofocus and manual override
Cons: Relatively harsh rendition of out-of-focus areas of the image, Somewhat susceptible to flare with direct light sources in or close to the frame, Inconvenient design of tripod mount ring (can't be detached without taking lens off camera)
Excerpt: A year ago Canon unveiled an upgraded version of one of its crown jewels: the 70–200mm f/2.8L IS lens. The original, debuting nearly 10 years ago as one of the first f/2.8 lenses with IS, was fast, plus sharp at the wider focal lengths. It was heavy, though, and at $1,700 (street), expensive.
Summary: Overall this is a great lens but there's no escaping the fact that it's also a costly one. If you are a demanding Canon user for whom price is not the decisive factor then this is a lens that you'll want to own.
Summary: A favourite of the pros, this lens has just been updated. Can it match up to its hefty price tag though? Of all the pro lenses, the 70-200mm f/2.8 is probably one of the most popular. It’s range of telephoto focal lengths make it perfect for reportage style portraits and many sports.
