Here is a quick tip list
on letters for the HELP! desk:
A. You might want to check into the CRIS adapters for your older cameras that use hard-to-find 1.35v button batteries. According to these folks they are indeed adapters and they do not produce voltage. The adapters (MR-9) use micro circuitry to lower the voltage of a 386-size 1.55v battery to 1.35v. The circuit only operates while a load is being applied--this keeps the battery from draining when not in use. The adapter is a one-time purchase and it is recommended the inserted .battery be changed yearly. The adapters normally stocked can be seen at this link: www.criscam.com/mba.htm. Or you can purchase this size battery from Scherer Supplies, Box 250, Ewing, VA 24248; (276) 733-2615; fax: (276) 733-2073. They are zinc-air batteries with no mercury or cadmium. The MX625 replaces PX625 and PX13; MX675 replaces PX675.
A. I called my technical contact at Leica to get an accurate answer for you. ROM stands for "Read Only Memory" just as it does for computer applications. While ROM lenses will work with any R-series Leica (R3 to R9) their electrical contacts only transmit information between the lens and camera on the newer Leica R8 and R9 cameras. They are mainly helpful when using flash with these newer cameras as they let the flash electrically communicate with the lens so it will know the lens focal length and can adjust the flash coverage to match. You can obtain information about Leica products by calling them toll free at (800) 222-0118 and speaking with the technical representative.
Polaroid Back Instructions?
A. Have you tried contacting Polaroid for suggestions on the proper insertion and use of their various types and sizes of pack films? They tend to work closely with NPC and should be able to assist you in the proper loading of your Polaroid pack film back. You can contact Polaroid at www.polaroid.com or access their technical assistance people at (800) 343-5000. You did not mention which size Polaroid pack film you use, so I cannot accurately answer myself. I assume you inserted the new film pack (with the black light-tight paper covering the sensitive film/paper inside) with the paper facing the back of the NPC back instead of toward the front.
Maxxum Lens Options
A. Any brand of lens having a Minolta AF bayonet mount would be compatible with your older Minolta Maxxum 7000 AF SLR. Some of the independent brands of lenses you might want to consider are Cambron, Phoenix, Promaster, Sigma, Tamron, Tokina, Quantaray, and Vivitar. Just be sure the lens has a Minolta AF mount, not a mount intended for another major brand of SLR camera. To get an idea of what's currently available, and the MSRP prices, get a copy of our 2004 Shutterbug's Photography Buyer's Guide which should be available at better newsstands and camera stores this fall.
Kowa Lens Query
A. I believe the Kowa anamorphic lens you purchased was intended for use with a 16mm movie camera (from the 16-D in the nomenclature) to compress the horizontal image recorded onto the film. But to get the intended widescreen effect when viewing (projecting) the film, you also needed a similar lens on the projector to uncompress the image and thus fill the wider than normal projection screen. This permitted conventional movie cameras to be used to record "Cinerama-type" widescreen images without needing a special movie camera lens. These were add-on lenses that simply screwed into the conventional taking lens to convert them. This was similar to the screw-in wide angle and telephoto adapter lenses that used to be offered for 35mm cameras that did not take interchangeable lenses. I'm sure your lens could be used today, but I believe you would need another lens for the projector to achieve the desired final widescreen effect. As to today's value, I have no idea, as I could not find any reference to it. If any readers have a more accurate description of your lens, we will pass their comments on to you. We appreciate your favorable comments about the department. We do our best to provide accurate information about any conventional (non-digital) photographic questions.
A. I checked several different replacement battery sources and came up with nothing until calling Cell Energy, Inc. at (800) 321-0714. They said they have a Duracell alkaline replacement for your mercury 640 battery available. You can also contact them via their website at: www.batteries4everything.com. I hope you get your old meter operational again.
A. I have not heard of this type of daylight slide viewer for many years. When I worked for GAF Corporation (Ansco) well over 30 years ago we sold a device called Mirascreen by Sawyers, a box-shaped device that you placed in front of any slide projector and it showed the slide image on a screen about 9x9 which was viewable in normal room light. But I have not heard of Sawyers products for about 20 years since Hanimex bought the projector line. Have you tried contacting Kodak at their information hotline, (800) 242-2424, or Telex Communications, 12000 Portland Ave. S., Burnsville, MN 55337; (952) 884-4051; www.telex.com? A firm I have in my old files that repaired AV equipment was Ritz Audio Visual Associates, Inc., 6620 Virginia Manor Rd., Beltsville, MD 20705; (800) 543-0582; www.ritzav.com. They might know where such projectors are available today. If any readers are more knowledgeable about old AV equipment please contact us and we will pass the information on to you.
A. Have you contacted the current U.S.A. distributor of Gossen meters, Bogen Imaging Inc., 565 E. Crescent Ave., Ramsey, NJ 07446; (201) 818-9500; www.bogenimaging.us? Possibly they can direct you to a repair facility if they cannot do this themselves. Or you might want to contact one of these firms I have listed for repairing older meters: Quality Light Metric, 7060 Hollywood Blvd., Suite #415, Hollywood, CA 90028, (323) 467-2265; or Exposure Meter Service, 124 Briar Hills Circle, Springfield, NJ 07081, (201) 376-2781.
A. I recently found out that Stephen Gandy is the exclusive U.S.A. importer of Voigtländer products. I believe he can also direct you to repair facilities. You can contact him on the web at: http://CameraQuest.com/inventor.htm. When I checked his site, I did not see any mailing address or telephone number for him, but there were a number of new and used products listed that might fit your requirements. I hope this helps you get your accessories into gainful use again.
Owners Manual Search
A. There are a couple of places I refer most readers to for old photo manuals. But, I don't know if they carry instructions for brands of products that are not typical, such as your Allied Radio meter. I have included the website addresses, too, as you might be able to access them from a computer in your library, as I did a few years ago when my computer was out at the shop being repaired. Try: John S. Craig, PO Box 1637, Torrington, CT 06790, (860) 496-9791, www.craigcamera.com/ib_a.htm; or Finger Lakes Photo Books, PO Box 1002, Elbridge, NY 13060, (315) 491-1188, www.photobooksonline.com. There is another website for camera manuals: www.manualsrus.com. We are pleased to hear you like the contents of our publication.
