Tamron 28-300mm f/3.5-6.3 XR Di VC LD Aspherical IF Macro AF This lens was very recently announced. The lens isn't reviewed anywhere else to my knowledge yet (except for slrgear...I just posted there). A friend let me borrow it and here's what I think: I don't own the lens...I merely borrowed it for a weekend from a friend. For the focal length range and VC alone the price is just justified, barely. I don't think the VC is as good as Canon's IS (seemed really jerky and I feel I threw away a lot more 300mm shots hand-held vs. when I used the Canon 70-300 IS USM lens). I hated how the lens trobmoned outwards on its own when hanging downwards unlocked. Seemed soft towards the edges at both extreme focal distances at f/3.5 and 6.3 respectively. Need good high resolution samples with exif data, shot with a Canon 30D? Sample Photos -Roy
