K&F Concept K&F HIGH PRECISION LENS ADAPTER QBM-EOS R

The K&F High Precision QBM-EOS R Lens Adapter allows Rollei QBM-mount lenses to be used on Canon EOS R-series cameras, featuring an anti-reflection interior and full manual control for creative vintage-lens shooting.

This adapter provides a reliable and precise solution for mounting classic Rollei QBM lenses onto modern Canon EOS R-mount mirrorless cameras such as the EOS R, RP, RA, R5, R6, and more. Built with durable metal construction and anti-reflection treatment, it minimizes internal reflections and enhances image clarity. Designed as a fully manual adapter with no electronic contacts, it does not support autofocus or electronic aperture control; your lens will operate at its maximum aperture by default. Ideal for photographers who enjoy the character and rendering of vintage Rollei optics, this adapter ensures a secure fit and smooth manual focusing. Before first use, the cameras release shutter without lens setting must be activated to allow proper operation.
