yes, I mounted lens on the camera to check, these mamiya SX lenses ( excellent optically ) have big outer aperture rings near the flange and this ring is in the spot where the pin hole would need to drilled so it wont work because it wouldnt lock or the aperture ring wouldnt be able to be turned once mounted. jco

If you're comparing it to a K lens, they tend to have a slot rather than a hole. That slot is typically longer than it needs to be. I've done this on about a half-dozen lenses. First thing I do with my M42/K adapters is remove the damn clippy thing. If you can't drill the hole, you just have to be careful to not dismount the bayonet while focussing... :) -Cory -- ************************************************************************ * * Cory Papenfuss, Ph.D., PPSEL-IA * * Electrical Engineering * * Virginia Polytechnic Institute and State University * ************************************************************************ * -- PDML Pentax-Discuss Mail List [EMAIL PROTECTED] http://pdml.net/mailman/listinfo/pdml_pdml.net -- PDML Pentax-Discuss Mail List [EMAIL PROTECTED] http://pdml.net/mailman/listinfo/pdml_pdml.net
