K&F HIGH PRECISION LENS ADAPTER,Anti reflection,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.

The K&F High Precision Lens Adapter PK/DA–EOS R 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, this adapter 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.
