Canon EF 70-300mm f/4-5.6 USM L IS - Full Format Review / Test Report
7 May 2011
Conclusion: The Canon EF 70-300mm f/4-5.6 USM L IS delivers high quality results throughout the zoom range but especially at 70mm. At 300mm it is clearly better than its in-house cousins (EF 70-300mm f/4-5.6 USM IS & EF 70-300mm f/4.5-5.6 USM DO IS) reaching very good to excellent center results combined very good(-) borders/corners. The light falloff at max. aperture is comparatively well controlled. The amount of distortions is about average for a lens in this class.

10 January 2011
Conclusion: The Canon EF 70-300mm f/4-5.6 USM L IS shines when used on an APS-C DSLR. It is capable of delivering very high quality results throughout the entire zoom range and across the whole image field here. Distortions, lateral CAs and vignetting are negligible. The bokeh is generally smooth and out-of-focus highlights are rendered perfectly on the cropped format.
Summary: The Canon EF 70-300mm IS USM f/4-5.6L keeps the good name of the L-series in honor and is very good. The Canon 70-300 mm L lens is ideal for professionals and wealthy, advanced amateur photographers. The Canon 70-300 is very well built and protected against dust and splash water. The autofocus is fast and the image stabilization showed an excellent performance in our review. All optical properties vary from good to excellent.
Pros: Very high image quality, Very solid finish, Highly effective image stabilization, Beautiful bokeh for f/4-5.6 lens
Cons: High price, Somewhat susceptible to ghosting
