Product Description
Canon EF Autofocus Lenses Canon s reputation for excellence in optics has been well established for years. And with the introduction of EF lenses for the EOS, it s only getting better. EF Lenses have the largest diameter mount of any 35mm camera, which not only strengthens the whole system, but permits optical innovations never before possible. L-Series lenses have better sharpness and contrast because Canon uses aspherical elements to eliminate spherical aberrations. In addition, the L-Series telephotos use UD (Ultra-low Dispersion) glass to reduce chromatic aberration resulting in more accurate colors. A built-in Ultrasonic focusing Motor (indicated by USM) provides pro-quality AF speed with split-second accuracy. Canon maintains the image quality and focus speed with a more compact and less expensive zoom. Perfect for the photographer on the go.

Superb lens.......2005-11-18
The ef 70-200/f4 is a fabulous lens. It's very sharp, has good depth of field at f4 and is a joy to use.
The focus can be set to 3m to infinity or 1.2m to infinity. The shorter length is very good for close ups of flowers or similar. If its left on 1.2m it may hunt when trying to focus. You can also set to manual focus.
One issue with the lens is back focus, if you are shooting at something when there is a bright, or high-contrast background, you may find the camera has focussed on the background.
I use my 70-200 f4 on an EOS20D, I have taken thousands of shots with that combination, photogrphing; cricket, riding, birds, flowers, people, aircraft and stars. Other than the minor issue of back focus, I have had trouble free shooting. The lens is well worth getting.

GREAT Value for money.......2007-12-02
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!
