Here is an image from the new Tamron SP 70-300/4-5.6 Di VC USD
Unfortunately I've been unable to be afield much lately. I took a few minutes this morning to try out my new Tamron 70-300mm.
The VC stabilization appears to be better than the stabilization on the Nikon 70-300 VR by at least a full stop. The USD focus is sweet. The AF ring is bigger and much more practical than on Nikon's 70-300 VR.
And this is a sharp little lens.

Tamron SP 70-300/4-5.6 Di VC USD
ISO 400 No Noise Reduction
1/640 @ F13 (I was so close F13 was as wide an aperture as I could use and still get Gull's bill close to in focus)
