Canon EF 75-300mm f/4-5.6 III USM

Review Date: Sep 7, 2005 Recommend? yes | Price paid: $175.00 | Rating: 6 

Pros: Price and size. It's a good consumer lens for the price. The USM AF is certainly much faster and quieter than the AF on similar lenses by Tarmon or Sigma. Pretty decent image between 75 - 150 mm range.
At 200 - 300 mm range, you really need to stop down to f/8 or more to get sharp pics. You get noticeable CA when shooting high contrast subjects at f/5.6 at 300mm, but it goes away when you step down to f/16 or f/22.

I shot a silver Honda Accord's back from 40 yards at bright sunlight. at 300 mm and f/5.6, you could notice CA in the form of purple lines around the edges of the trunk and the license plate.

At f/22 the picture was crisp and no CA. For the price, this is a good lens. If you're picky, then spend $1200 for the L series.
