If you're looking for a small and lightweight wide-angle zoom lens for your full-frame camera, Tamron's new 17-35mm f/2.8-4 Di OSD could be the answer.
Tamron already produces a large and fast SP 15-30mm f/2.8 Di VC USD, but this new lens is a much more compact alternative, measuring just 90mm (3.5 inches) and tipping the scales at 460g (16.2oz). It doesn't quite offer the same constant f/2.8 maximum aperture as its larger sibling, but it does have a respectable variable maximum aperture of f/2.8-4.
