Nikon has announced a pair of new professional AF-S lenses, first comes the AF-S 14-24 mm F2.8G ED which promises to offer a huge field of view on the new FX format D3 digital SLR. The lens is made up of fourteen elements in eleven groups, two of which are ED glass, three aspherical. There's also a "Nano Crystal Coat" which features in all the lenses announced today, it's designed to cut down internal reflection within the lens which can be a particular problem with the reflective surface of a digital SLR sensor. Next is the AF-S 24-70 mm F2.8G ED a new slimline (by F2.8 lens standards) lens which will provide wide to just beyond standard field of view on the D3. Both lenses will be available this November, no pricing yet. (04:00 GMT)
Nikon has today announced three new super telephoto lenses to coincide nicely with their first full-frame DSLR, the D3. They are the AF-S 400 mm F2.8G ED VR, the AF-S 500 mm F4G ED VR and the AF-S 600 mm F4G ED VR. These fast aperture 'big reach' lenses are perfectly suited to the types of photography the D3 is aimed at; sports and news. All three lenses feature 'Nano Crystal Coat' which cuts down internal reflections as well as Nikon's Vibration Reduction II optical stabilization system which claims to enable up to four stops slow shutter speeds. Weight wise obviously these are big lenses, in order; 4.9 KG, 3.9 KG and 5.1 KG. Available this November, no pricing yet. (04:00 GMT)
