I just had an epiphany. When using the MPCC, I can’t use a low-profile T-ring as the MPCC requires 55mm back focus, so I need the standard 11mm T-ring still. The MPCC is not supposed to change the focus position when in use is it, so it will have no effect on my Camera focus position?

I’m wondering if it’s a bad idea to consider lubricating my existing T-ring to see if it’ll free up the binding. i certainly don’t want fluids flowing down into my camera body, or back into the scope, but is a gentle wipe with a lubricant infused piece of cloth still a bad idea? If it’s just bad threading, it’s not going to help, but if it’s rough threading, it might.

Thanks. Russell.
