The lens is very well built, and fairly light. The focus is extremely quiet, and the lens literally focuses in a blink of an eye. The focus and zoom colars are huge and easy to use. The focus colar doesn't rotate while the lens is auto focusing which makes it very easy to hold.

This is the lens to get for daylight use where you want the lightest, least expensive tele zoom yet still want a fast and excellent lens. It is ideal for daytime sports because of it's very fast focusing and great image quality.

The Canon 70-200mm f/4L USM is one of the cheapest L-series lenses available. Despite this fact, it is a very well-performing lens. It has two big brothers, the 70-200mm f/2.8L USM and the 70-200mm f/2.8L IS USM, both of which are over twice as expensive.

This smaller, lighter, slower version is a very nice lens for the money and produces excellent results. Being that much smaller and lighter, it makes a good companion for some of the smaller cameras in Canon’s line up such as the 20D and the 350D without the price and weight penalty of the top end lens.

If you need a telezoom, this one is among the best. The EF 70-200 4L USM has similar build and optical quality as the famous EF 70-200 2.8L USM, but at half the price, weight and shy a F stop.

I frequently use a 62mm Nikon 6T closeup lens with the 70-200 f/4 L for macro photographs. While not at quite the same level as a dedicated macro lens, this setup yields excelent quality images.

If you do not need your 70-200mm lens to be faster than f/4 and don't need IS, the Canon EF 70-200mm f/4.0 L USM Lens is your lens. The 70-200 f/4 L is a great value and a highly recommended lens.

The Canon EF 70-200mm f/4 USM L is a very harmonic package combining exceptional build quality with an excellent and very even optical performance throughout the range.
