Broaden Your Lens Line-up - with M42 to EF mount compatibility
Mechanical adapter couples M42 screw mount lenses to Canon EF bayonet, matching flange distance so lenses can be mounted and focused. No electronic contacts are present, so lens-to-camera communication is not transmitted.
Access to vintage and specialist M42 glass such as Zeiss and Pentax expands creative options without buying new branded EF lenses. Manual focusing and lens character bring unique rendering to portraits and landscapes.
Full Manual Aperture Control - thanks to manual diaphragm operation
Absence of ROM means aperture must be set on the lens itself, or by pre-setting the diaphragm before mounting. The adapter preserves mechanical linkage where applicable, allowing direct control of the aperture ring.
Precise depth-of-field control becomes straightforward for creative work and macro shooting, especially when automatic aperture coupling is not required. Owners can fine-tune exposure and bokeh without electronic intervention.
Reliable Mounting for Field Use - with durable metal construction
Machined metal construction provides a rigid interface between lens and camera, reducing play and maintaining alignment under regular use. The robust finish ensures longevity when changing lenses frequently.
Secure fit reduces the risk of wobble or misalignment during shoots, making the adapter suitable for location work and repeated lens changes. A dependable mount protects both camera and lens connections.
