Conclusion

When we first saw the new Canon EF 70-300mm f/4-5.6 L IS USM lens, we thought it just looked like a standard 70-300mm lens with a white overcoat on. After using the lens for some time, we're blown away by the image clarity, sharpness, build quality and speed of focusing.

The existing 70-300mm DO lens does make us wonder whether the L lens is really necessary because the quality of that lens is so similar and it's 5cm shorter. But it's not white and doesn't have the letter L and for a lot of people it will be the image that it conveys that will be worth the extra money. If that's you then you won't be disappointed by this lens.
