K&F Concept K&F High Precision Lens Adapter PK/DA-EOS R

The K&F High Precision PK/DA to EOS R Lens Adapter allows Pentax K-mount lenses to be used on Canon EOS R-mount cameras with a durable, anti-reflection design and fully manual operation.

This adapter is engineered to let photographers mount classic Pentax K-mount lenses onto modern Canon EOS R-series cameras, including the EOS R, RP, RA, R5, R6, and others. Built with high-quality materials and an anti-reflection interior, it ensures improved light transmission and minimized internal glare. As a fully manual adapter with no electronic contacts, it requires manual focusing and does not support electronic aperture control; your lens will operate at its widest aperture by default. Perfect for creatives who want to explore vintage Pentax optics on a cutting-edge mirrorless system, this adapter provides stable performance and a precise fit. When using the adapter for the first time, be sure to enable your camera's release shutter without lens setting.
