75mm Noctilux bayonet tolerance

Why does my 75mm Noctilux have rotational movement of a couple of degrees either way when locked to my SL2-S via Leica adapter & M10M ?

Kind regards,

Probably the adapter has slacker tolerances.

Two interfaces = twice the tolerance.

Thanks for your responses.

You are right about the adapter but it does it on my M10M admitably not as much.

I have no such movement on my M10M when using 50mm Summilux or 28mm Elmarit to the point you need to use bit of effort to lock it in.

Just more with the Noctilux 🤷‍♂️
