Manufacturer's Description
High-performance, L-series telephoto zoom lens combining light weight and compactness with an f/4 maximum aperture. Inner focusing and the ring USM enable quick and quiet autofocusing. Also, a circular polarizing filter can be attached and used without difficulty because the front lens element does not rotate during focusing.

Superb lens
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.

Super lens
Bought this lens to work with my new EOS 40d.

Looks great on the camera, weight / balance is very nice and compliments the 17-85 kit lens very well. I like to use auto-focus but still be able to tweak the focus manually - this "full time manual" is not available on the cheaper 70-300 zooms which use gears in the focus mechanism.

Bear in mind that the "crop factor" on a 40d or similar means that this is equivalent to a c100-300 zoom on a film camera.

The lens focuses almost instantly and gives lovely pictures with really bright colours.

If you have a 40d, I'd recommend this as a very effective addition to a great camera.

Best value piece of Canon gear?
It's certainly up there with the cheap 50mm f1.8.
What you get is razor sharp images, quality construction and beautiful photos that seem to capture the scene as it appears without the lens putting its own spin on colour or contrast. Bokeh is creamy too.
If you're considering the 75-300mm IS, take a look at this before you buy. What you lose in length and IS you gain back with interest in quality.
My new favourite lens.

**UPDATE**
Sold! Swapped it for the 2.8 version purely for the extra light. A great lens that's well worth the money, but one you may well find yourself 'upgrading'.
