i just got a mamiya rb and there seems to be a problem with shutter on the lens. no matter what speed i choose, when i trigger it the leaves shut close down immediately, even wheni put the speed on 1 or T.

Make sure the selector on the side of the shutter is set to "N" (for "normal") instead of "M" (for "mirror up"). If the latter, the shutter will close when the mirror fires (as it would normally) but it won't fire until the release under the selector is fired with a cable release.
