Oversized PL mount lock on Arri 2C not allowing lens to go all the way in

[Paulo Arellano]

Hey guys Im trying to fit an Arri Ultra prime on this 2C I got but the lock on the PL mount wont allow the lens to go all the way in, its hitting the aperture ring. Lens fit fine on my Arri BL-3.

Does anyone know a place where I can buy a smaller lock? I can see that they can be unscrewed and replaced.

Try removing the locks and machine them down.

Assuming you only wan to use this lens once in a while, you could probably just remove the ears, put the screws back in, and use it that way for a while
