You're paying a premium for gee-whiz technology and superior focus flexibility over the non-DO Canon 70-300mm IS, as well as losing 1.7" (43mm) in length, but otherwise I prefer the non-DO version at half the price.

For candid street photography, of the type I have done in India and China, the 70-300 DO would be a great companion. The small size, black color and fast, silent focus would make it a winner.

The main benefit of the DO optics in the 70-300 is the reduction in length (but not weight). A short lens has obvious attractions for candid photography.

I can confirm that EF 70 – 300mm 4.5 – 5.6 DO IS USM is an excellent lens from many perspectives. It's main benefits are compactness, fine quality, second generation IS and fast focusing.

It seems that those who realize what the 70-300DO lens is, and what applications it's aimed at, generally like it and are happy with it. Those who think it might be a small, light lens with the optical performance of an "L" series prime will be the ones who are disappointed.

The Canon EF 70-300mm f/4.5-5.6 DO IS USM is a compact, very fast-focusing zoom telephoto lens that provides generally excellent imaging function including excellent image stabilization at a high price.

If I didn't already own the superb Canon 70-200mm f/2.8L IS I'd be very tempted by the new DO, since I'll take the trade-off of 2 extra stops of aperture for the extra focal length any time. Nevertheless the 70 - 300mm f4.5-5.6 DO IS is a very appealing lens indeed.

The Canon EF 70-300mm f/4.5-5.6 DO IS USM Lens is an excellent travel lens - having a lens that is easily carryable will get MUCH nicer shots than a lens left at home because of its size/weight.

From a performance point of view it delivers all that a consumer has hoped for - high resolution figures in conjunction with low distortions, low vignetting and low chromatic aberrations and all packaged in a quite sturdy, small package with high speed AF.
