Noisey and Very Slow to Focus

Canon EF 75-300mm f/4-5.6 III LensIf you use a Canon digital SLR and are happy with your 18-55mm kit lens, then getting this telephoto lens is your natural next step. You will be able to increase your zoom reach to the point where you can photograph birds in somewhat far-off trees, and be able to zoom and frame several yards away on just about anything that interests you. What you cannot effectively do with this lens, though, is to take fast sport shots. It is just waaaaaay too slow. [g index]

If you need a fast low light lens, this isn't it. If your primary objective is to take pictures in available light situations such as weddings and concerts, then get the 80-200mm f/2.8 or the 70-200mm f/2.8 IS instead.

The lightest 4x telephoto zoom lens in its class. Ideal for slow sports, portraiture, animals, etc. The telephoto effect can make the picture look compressed or have excellent background blur. At the 300mm focal length, you can fill the frame with a postcard from 4.9' away.

Features

This high-performance 4x zoom lens is distinguished by such features as a newly developed micro ultra-sonic monitor (USM) that makes autofocusing quicker and quieter, along with an improved mechanism to make zooming smoother than ever. Plus, the front part of the zoom ring now sports a silver ring, giving the lens a luxurious touch. As with all Canon lens, this 75-300 model carries a one-year warranty.
