Last year I picked up a Minolta Maxxum 9xi on ebay and a few weeks later bought a 500 mm manual-focus reflex telephoto to use with it. The lens has the proper mount (works fine on a Maxxum 7000) but doesnt have the electronics (or something) that can be detected by the 9xi which causes the camera to prevent accidental exposures by locking the shutter. The manual that I downloaded for the camera advises that you should contact your nearest authorized Minolta service facility, which, of course, dont exist anymore. Does anyone know how to override the lockout so I can use this lens? Thanks!
