I've got a problem with the "A" contact on one of my FA lenses, and I was wondering if anyone on the list could help.
Basically the camera doesn't recognise the fact that the aperture ring is in the "A" position, so I can't use shutter priority modes. >From perusing Boz's K-mount site it looks as though the problem is simply with the "A" contact. The description of that contact for the KA-mount describes the lens contact as physically moving when the aperture ring is moved to the "A" position to make or break contact with the camera body. As far as I can tell this isn't true for later (F and FA) lenses, so I assume the switching is done elsewhere in the lens, rather than by moving the contact. Can any list member confirm or deny this hypothesis? I haven't seen my multimeter for years, so I don't know whether I'll be able to do any further checking myself. I'd also like to know what the likelihood is that this could be something I could repair myself, something a typical neighbourhood camera repairer could fix, or something that will have to go back to Pentax.
