This extremely high-quality PL mount adapter from 8Sinn, made in Poland, allows you to use PL mount lenses on RF mount bodies. Purchased new and used 7-8 times with an R5C. * Stainless steel PL mount flange. * Precision 0.005mm. * Infinity focus. * Aluminum alloy and stainless steel. * Black/Silver anodized I used it with a Canon R5C, but no longer need it as I've switched my camera system to L mount. There is some slight wear and tear, but overall it's in good condition.
