Canon EF 70-300mm f/4.5-5.6 DO IS Lens

Does anyone here have the Canon EF 70-300mm f/4.5-5.6 DO IS USM Lens? (The Fresnel lens.) With its relatively small size it looks like it would be a good travel lens but all the reviews say that it is soft. Reviews say that the Canon EF 70-300mm L is sharper but it is bigger. (Cost is about the same.) The Canon EF 70-300mm f/4.5-5.6 DO IS USM Lens appeals to me because it is short and it is not white like some of the telescopic L lenses.

I use my 70-300 DO quite a bit and find it plenty sharp. Like all 300mm lenses, don't put a UV filter on it. Do use the hood as it can flare some. One of its big benefits is that it has almost no chromatic aberration which makes it seem sharper.

I don't have a 70-300L lens to compare it to but I do find it sharper than the 70-300 IS (non-L) lens. The very small collapsed size is nice if you don't want to use much bag space to have a telephoto with you.

A good friend has the 70-300 DO IS and I borrow it frequently. It is indeed nicely small and relatively light.

Ron Mart's Blog has an article comparing the 70-300 DO IS vs. the 70-300L. It's surprising that the 70-300L isn't that much bigger than the 70-300 DO IS:
