Before I ebay my 55 mm f/1.2 Nikkor-O CRT or Oscilloscope Lens, I decided to offer it for a swap, to you guys. This text below is the one that a swedish photographer used when he auctioned his example of this lens. Cheers, Gui ---- 55 mm f/1.2 Nikkor-O [CRT or Oscilloscope Lens] This very rare speciality lens was made for industrial use to record faint cathode-screen traces and came with a long Leica-thread mount. It can be mounted on any Nikon camera with the LF adapter and a restricted focusing range is achieved by rotating it in the adapter. It is optimised for the limited magnification range 1:4.4-1:5.5 only and here it delivers exceptionally sharp images. Peak performance is between f/1.4 and f/4 so the lens is extremely useful for hand-held close-ups. Its quality for flower photography is further enhanced by a negative field curvature thus enabling both central and outer floral areas to be in sharp focus even at wide aperture settings. Enscribed Nippon Kogaku Japan No. 721431, this absolutely superb example of the legendary Nikkor 55mm f1.2 Oscilloscope lens really is a collector's or user's dream come true. A most scarce lens, designed for use within industrial photography, these are seldom offered for sale in this kind of condition. There really is very little on this lens that would distinguish it from a new one. The optics are perfect, front and rear, with no scratches at all. For further information regarding this lens, please take a look at these pages: http://www.naturfotograf.com/lens_spec.html written by Björn Rörslett, a well known and respected Norwegian nature photographer. Björn uses his with a Nikon D1X with quite outstanding results. http://homepage2.nifty.com/akiyanroom/redbook-e/repro/crtface2.html ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca
