I got my J9 a couple days ago and I was unable to mount it on the camera. I'm not experienced with interchangeable lens rfs but I'd heard the lens and camera both need to be on infinity. I have no problem removing and replacing the internal mt. sonnar. I figure just lining up the red dots a la SLR oughta do it but I just can't seem to get it to work right. Any advice would be appreciated.

There is no special technigue required.You set lens and camera to infinity, line up the red dots and push the lens towards the body while twisting the lens clockwise. If it doesn't mount, either the lens or the external mount on the body may be damaged.

there's a brass pipe protruding from the back of the lens, made of relatively thin brass, with three cuts in it. This has to catch the inside focusing ring-thing of the mount on the camera, when you set the lens to infinity and line up the red dots. Further, this has to move IN into the lens a bit when you push the lens on the camera for mounting.
Either this is rotated and cannot catch the three holes on the inner mount on the camera, OR, due to old lubricants it is stuck and when you push the lens after line-up of dots, it cannot move into the lens. The alignment you can check approximately by eye before you put the lens on; the moving-in you can check simply by trying to push this pipe thing into the lens by hand, or by putting something flat on it and pushing. It does need some force (there's a strong spring involved) but should go in by a pressure that you can exert with a few fingers.

the inner brass part pushes in, and I got the lens to mount flush but then it will not lock into place. that inner part definitely does not match the design of the internal mt. lens the camera came with. I thought the lens would mount properly on the external mountt, but I guess both must be engaged?
so I wonder what mount this lens is designed for. I suppose I'll have to send it back.
