Description

Adapt your vintage M42 screw mount lenses to modern Canon EOS R mirrorless cameras with this solid metal mount adapter from Hersmay. Crafted from aluminium and brass, this adapter enables M42 lenses (42mm thread) to mount securely on Canon EOS R, EOS RP, EOS R5 and EOS R6 full frame mirrorless bodies without gaps or play. The adapter supports manual aperture control and AV/M shooting modes, allowing you to unlock a vast library of classic and affordable lenses for contemporary Canon RF mount systems. As a manual-only adapter with no electronic elements, focusing and aperture adjustment require manual operation, but the precise engineering ensures a reliable, wiggle-free connection. Perfect for photographers seeking creative control and lens versatility whilst breathing new life into legacy M42 optics on current Canon mirrorless platforms.
