Just a minor note, I think when you view "1" through the peephole, you manually set the counter to "1", not zero. A person could view the peephole as a feature, to verify that the film advances. In theory, you could look through the peep hole after winding to frame two, and verify that the gears moved the film the proper amount. In practice, I have never had the time to bother. My twelve back, the only one I own besides my NPC MF-1 polaroid back, works perfectly, despite its age. By the way, I understand the A in A12 stands for Automatic, as it is more automated than the 12 back. Can you give any more detail about possible light leaks? Where would they be? Is there any sealing foam that could deteriorate in the 12 back? What are signs that gears might slip and cause bad framing in a twelve back? At this time, I would comment that the Hasselblad line is infamous for the backs failing to advance the film, causing unintended multiple exposures. A good friend, who is employed at a pro lab here in town (Washington, DC), reports that this problem has set some of his clients to crying. In his opinion, the motorized rigs are the worst in this respect. Back to the original excellent response, service might be a good idea. Not only for light leaks, but also to check the gears and what have you. There is another theory that the gears can be serviced, for improved reliability. Peter p.s. Anyone been able to mod a Kiev 12 back to fit a Hassy?

AUTO fill flash... 1. Set the flash to AUTO. Set the film speed on the flash 2 to 4 times the speed of the film you're shooting with. I use 4 times for most bright, sunny days. It looks more natural. 2. Check the f-stop scale on the flash to see what auto f-stops you have available, and pick one. 3. Set the SAME f-stop on the camera and pick the shutter speed that gives the proper ambient light exposure. 4. If you set the film speed on the flash at 2 times normal (a 1:2 fill), stop down the lens one stop without changing the shutter speed; if 3 times (a 1:3 fill), stop down 1/2 stop; if 4 times (a 1:4 fill), don't stop down at all. 5. Shoot your pictures and get auto-fill flash. NOTE: If you want to use this technique with a 35mm camera or any camera with a focal plane shutter, don't set the shutter speed higher than the highest flash sync speed. Adjust the f-stop on the flash and camera accordingly, but make sure than the f-stop settings are equal. Still do Step 4, though, to compensate for the additional light from the flash. -- Patrick Bartek (NoLife Polymath Group) bartek@skylink.net http://www.skylink.net/~bartek ------------------------------ Date: Tue, 27 Jan 1998 14:44:12 -0800 From: Dave Munroe To: hasselblad@kelvin.net Cc: dmunroe@popmail1.vcd.hp.com Subject: Hasselblad Lens Guide - update Message-ID: <34CE633C.289C@vcd.hp.com> This is a multi-part message in MIME format. --------------3C93CF94F3E Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Folks, Please consider the attached as the latest revision of the guide, superceding my earlier posting of today.

It is an easy fix to make, in my case, it was done while I waited.
