Having gotten by with bird photgraphy with cheaper zoom lenses I bought this Prime Telephoto lens knowing I would be paying a lot for a minor gain by comparison. The cost/image quality curve makes each little improvement very expensive; but it is necessary if you want consistantly good results.

This lens is as sharp as a tack without the added weight of it's big brother, the f2.8 version. When you are carrying a load of equipment on your back you'll be glad you have the 300mm f4.0 instead of the heavy ones.

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Lightweight; Rugged; Strong Construction

I bought this lens mostly to photograph wildlife and I have taken some great shots with it in the short time I have had it. The lens is light weight and easy to carry around in the field for long periods of time without causing fatigue.

I bought this lens as I needed more pulling power than my 70-200 f2.8L IS could give me. Initially I was surprised how compact and lightweight it was. It is no bigger than the 70-200 f2.8 and it is noticeably lighter too.

The Canon EF 300mm f/4 L IS USM Lens is another excellent lens in the Canon L Series . While it has enough focal length to feel long, this very-well-built lens remains relatively small and light. Image quality from the 300 f/4 L IS lens is excellent.
