Manufacturer's Description
This high grade telephoto zoom lens responds to the exacting requirements of professionals and advanced amateurs, yet at a reasonable price. One artificial crystal fluorite and two UD (Ultra-low Dispersion) glass lens elements in its optical system eliminate secondary spectrum, which is often the Achilles' heel of telephoto lenses resulting lower picture quality. These elements assure high resolution and high contrast throughout the entire zoom range. The latest optical design gives a minimum focusing distance of 1.2m and 0.21x maximum magnification. This lightweight, compact zoom lens, having the same level of optical performance as EF 70 - 200mm f/2.8L USM, assures good portability and operability. The ring USM (Ultrasonic Motor) and inner focusing system achieve high-speed silent autofocusing. Manual focusing, even while in AF mode, is possible thanks to full-time manual focusing mechanism. Extenders EF 1.4X and 2X can be used with this lens, and the optional Ring Tripod Mount A (W) is being marketed concurrently.

Customer Reviews

Magic lens
It's incredibly sharp, edge to edge and across the zoom range with good colour and contrast and a mind boggling 4 stop IS. Lab tests I've read indicate that the performance is only very slightly worse than equivalent Canon 'L' primes, and that's quite an achievement in a zoom.

It's also much smaller lighter when compared with the f2.8L, and not that much heavier than the non IS version. I can carry it around all day, where'd I'd rather not lug the f2.8, and that's really what it's all about.

Other than the fact that it only goes to 200mm and is white I really can't think of a bad thing to say about it. I can't be the only person that would be prepared to pay a little more for a black 'L' lens...

The lens is really quite long (not much shorter than an un-zoomed 100-400L), but *doesn't* extend (or rotate) when zoomed and the zoom ring doesn't have to be turned too far to go from 70-200. You can still manually focus with AF switched on and focusing is as quick and quiet as you'd expect from an 'L' series lens, so it copes really well with moving targets.

If you have the money, can settle for 200mm top focal length, want to take a lens out and about and don't mind white, it's almost a no-brainer.

GREAT Value for money
This was my first 'L' lens & got me completely hooked on the better image quality.

It is light, so sits comfortably on the camera for football matches & can be hand-held comfortably.

f/4 means it can't be used indoors but is great for photoing the kid's football or the dogs outside.

If money is short, you want quality & don't need the f/2.8 or the IS - then this is the lens for you!

Best pro-quality telezoom.
This is the best trully profesionable and affordable telezoom. Nothing like cheap 70-300 lenses, it is highly quality able to produce stunning pictures.

Image quality is beyond dispute, autofocus is almost instant and totally accurate.
It is the best L grade lens for its price.
