Manual and Electronic

Q: I enjoyed Richard Sibley's article on pancake lenses (AO 26 March), but was curious about the Nikkor 45mm f/2.8P lens that featured in the piece. Despite being a manual lens, it has electronic contacts so that aperture information can be communicated with the camera. Are there any other Nikon manual-focus lenses that also have electronic contacts so they can be used with automatic exposure modes on modern DSLR camera?

A: I spoke to Gray Levett of Grays of Westminster www.graysofwestminster.co.uk , who kindly lent us the 45mm f/2.8P lens featured in the article. He told me 'Nikon had a 500mm f/4P Nikkor IF-ED optic in its manual lens range, and produced, to special order, the 1200-1700mm f/5.6-8P Nikkor IF-ED which was the Godzilla of all manual-focus Nikon lenses. We had one here briefly and, if I remember it correctly, it cost £53,000. Its specification is: focal length 1200-1700mm, aperture f/.5.6-f/8, lens construction 18 elements in 13 groups (3 x EDs), weight 16kg, dimensions 237mm diameter x 880mm long (overall), filters 52mm drop-in. It was designed to cover an American baseball field, or baseball diamond as it is sometimes known.
