Tamron announces 10-24mm Ultra-Wide Lens
Aside from its 18-270mm VC Ultra-Zoom, Tamron has also announced a new 10-24mm Ultra-Wide lens for Nikon and Canon mounts.
Covering a 16-37mm zoom range (in 35mm terms) this f/3.5 - f/4.5 lens also features a minimum focus distance of about .24m though out its entire zoom range.

Tamron is probably going to price this lens just above the excellent Sigma 10-20mm (currently at just over $500 at Amazon.com) but well below Canon’s 10-22mm f/3.5-4.5 and Nikon’s 12-24mm f/4.0. Or for those of you who might see a Nikon D700 or D3 or a Canon 6D (or any full-frame DSLR) in your future - you might also want to look into the Sigma 12-24mm f/4.5 - 5.6 which can cover the full 35mm frame, something which all the other previously mentioned ‘digital only’ ultra-wide lenses can’t!
The Tamron 10-24mm f/3.5 - 4.5 will be available in Japan in late September 2008, and should make its way to the rest of the world in time for Christmas. We will have sample images here on WhatPhotogear.com as soon as they become available. Stay tuned!
