Summary: Tamron is a third-party lens manufacturer, which has produced excellent lenses in the past. This offering is the 10-24mm lens, designed to replace the company's first wide-angle lens exclusively for crop-frame cameras -- the 11-18mm. The lens is available in , , , and mounts.
Conclusion: The SP AF 10-24mm f/3.5-4.5 Di II LD Aspherical (IF) is Tamron's second attempt at a wide angle zoom for DX cameras, and it certainly looks as though this time the company has come up with a more compelling product than its older 11-18mm.
Pros: Equal widest angle in its class, and largest zoom range (by a whisker), Low distortion, Generally good resistance to flare
Cons: Soft wide open (low local contrast), Soft corners at all focal lengths and apertures, Wide diameter lens hood takes up lots of space in a bag

The lack of an AF motor also means that it won't be able to autofocus when mounted on Nikon bodies without their own AF...
