Poor at the long end

Summary: I have owned this lens and used it during a zoological expedition to Sierra Leone on a Canon Rebel XT. Yes it's nice and compact and uses the same filter thread as the standard zoom but all my photos at the 300mm focal end were soft and with low contrast. Test Report data/graphs actually confirm this result but don't discuss it much.
Summary: I bought it at B&H and returned it very quickly. Two issues (each is enough)1) It is hard to move. Especially, when the lens is pointed up. I found myself thinking twice before raising the leaden weight and forcing the lens to move. I just didn't bother with many shots. The only birds you will shoot are road kill, since the lens obliges when you point down.If you doubt me, put the lens to the side, and ask for a 70-200mm f4 L. Try its focusing and zooming. And compare.
Summary: This lens should be avoided by those with high standards of contrast and sharpness, usually found in better Canon lenses. Small details, object definition and color are subdued. The overall image needs much more manipulation in Photoshop to reach the level that the simple EOS 75-300mm IS lens displays. Portrait and action photographers will benefit from the advance technology in the IS and iris diaphragm. I'm sure there will be a version 2.
Not worth the money, buy the 70-400 f/4-5.6 IS L lens instead

Summary: I'm still deciding which lens to buy so I hired this lens and the 70-300 f/4-5.6 IS L lens and used them both for a week. They are both a very similar price, the L lens has a slightly wider aperture, but weighs more. Otherwise at least on paper they are fairly evenly matched. One of the benefits of hiring a lens is that you see how the lens would be after a couple of years use - the copy of the DO lens I had was floppy, and extended under it's own weight quite easily.
Summary: Ich hatte das alte Objektiv zwischenzeitlich, aber die von einem anderen User schon bemerkte Weichzeichnung hat mich das Teil ganz schnell in der Bucht versenken lassen. Dazu noch der große "Lichtbedarf". Habe jetzt ein 70-200/2.8 und da auch auf den IS verzichten, dank kurzer Belichtungszeiten. Und bei Bedarf wird einfach das Bild gecroppt.
