Hot on the heels of the D50 and D70s SLRs unveiled last week comes a pair of new DX-format zoom lenses from Nikon ? an 18-55mm and 55-200mm. Priced a penny under £200, both lenses are due out in black or silver and are expected to hit the UK high street in June. They are not designed to be compatible with 35mm film format cameras. The AF-S DX Zoom Nikkor 55-200mm f/4?5.6G ED delivers the 35mm viewing angle equivalent of an 82.5-300mm lens when used on the recently announced D50 SLR, for example (using a 1.5x conversion factor). Features on the 255g newcomer include two ED glass elements designed to help minimise chromatic aberration. Meanwhile, the AF-S DX Zoom-Nikkor 18-55mm f/3.5-5.6G ED optic is billed as an ?ultra-compact lightweight standard zoom lens?. It weighs in at 210g and delivers the 35mm viewing angle equivalent of a 27-82.5mm lens.
