0700 CET: Nikon has today announced the first in a range of new 'Nikkor DX' lenses. These lenses have a reduce Image Circle which means that the lens can be made smaller and lighter but still maintain a full image for the smaller D-SLR sensor (23.7 x 15.6 mm; a 1.5x FOV crop factor). The new lens is a 12 - 24 mm zoom with a constant maximum aperture of F4.0, the lens is also a 'G' type which means aperture can only be selected electronically and it uses a SWM (silent wave motor).
