The measures that Nikon will adopt include discontinuing production of all large format Nikkor lenses and enlarging lenses, as well as several of our film camera bodies, manual focus Nikkor interchangeable lenses and related accessories. Sales of these products will cease as supplies are depleted. Importantly, Nikon's film camera business will continue with our flagship model F6(TM) and with the FM10(TM), allowing the Nikon brand to continue serving the two strongest segments of the 35mm film camera market. Both professionals and dedicated amateurs who continue to view film as their preferred format along with students in need of an economical camera to learn the fundamentals of photography will have ideal Nikon products from which to choose. Additionally, Nikon will continue to produce the manual focus 85mm f/2.8D PC Micro-Nikkor(R). With the interests of its customers in mind, Nikon will offer continued post-sale service for products whose production has ceased for a period of 10 (ten) years from Nikon Inc.'s last date of sale.

So I've made a decision to offload the 4x5 camera system I have now to any interested buyers. The camera is an 'as new' Toyo CF45, which was bought as a 'used demo' (actually never used) from B&H Photo in New York, together with an 'A+' condition Rodenstock 150mm f/5.6 Sironar-N Lens in Copal #0 Shutter (no case), also from B&H Photo. I also have 5 Fidelity 4x5 film holders, Harrison Standard Changing Tent, Toyo Copal #1 shutter. The camera has only shot 30 sheets of film since I bought it in mid-2005. If anyone is interested in any of the items, or all of them as a set, please contact me. Terms will need to be payment by wire transfer to Australia or Thailand with shipping by Fedex or DHL from Thailand, paid for by buyer.

You must devide the original scale by the ratio of the focal lengths. The post you are thinking of is a description of how to measure the stops for an unknown lens. You can apply it here if you choose. There are two parts. The first is measuring the focal length, the second is measuring the size of the entrance pupil, which is the _effective_ size of the stop. Unless you need a very accurate focal length measurement you can assume the marked FL is correct. I give both measurements because they are done with the same tools. To measure the size of the entrance pupil you need a card with a small hole in it and a source of light, a small flashlight will do. The card is placed at exactly the focal plane for infinity focus. This is easy to do using a small flat mirror to autocollimate the lens. Place the mirror over the lens and adjust the card so that the spot of light reflected back to it is focused as sharply as possible. Get the spot close to the illuminated hole. Of course, you won't see it if its _exactly_ at the hole. Now, the lens is focused at infinity. Remove the mirror and replace it with a translucent screen. Ground glass is best but a sheet of thin paper will do fine. The circle of light projected onto the paper is an image of the entrance pupil. Measure its diameter and devide the focal length by this diameter to get the stops. The diaphragm is affected by the lens in front of it so the effecive size is not always the same as the physical size. In any case, this method allows measuring the effective size of the stop without any disassembly of the lens. To measure the focal length you need one additional measurement. Mark the position of infinity focus at some convenient reference point. The exact point does not matter because it is the shift of the lens that will be measured. Next focus on some convenient object to obtain an exact same size image. The distance the lens moves from its infinity focus position is exactly one focal length. This can be checked by measuring the total distance between image and object at 1:1, it will be exactly four times the focal length. If you want to know the locations of the principle points you can find them by focusing the lens at infinity and measuring one focal length back from the image toward the lens. When the lens is facing in its normal direction you will be measuring the 2nd or rear principal point, when the lens is reversed (front facing the image) you will be finding the first, or front principal point. The locations of the entrance and exit pupils can be found by using a camera which will focus at very close distances as a measuring tool. First, focus it on the rim of the lens cell or other convenient point. Then move it so that the iris is in sharp focus. The direction and distance the camera moves will give you the location of the pupil in relation to the reference point. While this is all easier to measure with a proper optical bench decent measurements can be made with a view camera and simple accessories. --- Richard Knoppow Los Angeles, CA, USA dickburk@ix.netcom.com From LNPhoto at twmi.rr.com Fri Mar 17 20:40:08 2006 From: LNPhoto at twmi.rr.com (Les Newcomer) Date: Fri Mar 17 20:40:13 2006 Subject: [LargeFormat] the rise of the spring back In-Reply-To: <001301c629e5$8370b890$06b5e704@VALUED20606295> References: <001301c629e5$8370b890$06b5e704@VALUED20606295> Message-ID: <3cbf13c8955733f1e38db8095b555126@twmi.rr.com> Okay, Dag and wet plate cameras didn't use a spring back, and a whole lot of English and European cameras stayed with the swing ground glass.
