Verdict

The Canon EF 70-300mm f/4.5-5.6 USM DO IS is a promising new approach ... on paper at least. The DO elements allows a much more compact design compared to conventional lenses and our camera bags are certainly bulky enough already so that's something to be appreciated for sure. However, optically the lens stays somewhat short of expectations. The 70-300mm DO IS is certainly sharp at 70mm but at 200mm and 300mm it's a bit softer than it should be. The contrast level could also be higher here at large apertures. The amount of lateral CAs is quite low though, so the DO element fulfills its promises here. Both vignetting as well as distortions are well controlled. The quality of the bokeh is a bit of a mixed back. The foreground blur as well as highlights are on the rough side whereas the background blur is pretty smooth.

The build quality of the lens is above average and in between Canon L grade lenses and the consumer grade league. The AF performance is on a very good level thanks to a ring-type USM drive (with FTM - full-time manual focusing). However, the biggest problem of the lens is its rather insane price level. It has a price tag well beyond the 1000EUR/US$ barrier and we've strong doubts whether the lens performance justifies this kind of financial sacrifice.
