William Optics M48 Adapter for Canon EOS Super high precision: brass precision for critical photographers
This William Optics M48 adapter is the high-precision version for your Canon EOS camera: CNC-machined from brass instead of aluminum. Brass is more dimensionally stable and wear-resistant, ensuring that the bayonet connection remains tight and play-free even after years of changing lenses.
For astrophotography, every hundredth of a millimeter counts: a sensor that is positioned exactly perpendicular to the optical axis results in round stars right into the corners. This adapter was made precisely for that purpose.




Features
- CNC-machined brass, more dimensionally stable than aluminum
- Lens mount: Canon EF, telescope side: M48
- Backlash-free coupling, even after intensive use
- Large M48 pass against vignetting
Compatibility
