Birger started it's journey with the Canon EF platform in 1999. Orignal product in foreground. The Birger RD-EF1 platform is now not recommended for new designs.

This extensive legacy, and widespread compatibility with EF lenses is captured with our new birgerCTRL for Canon RF product, when combined with the Canon Mount Adapter EF-EOS R, pictured in the background. Make a seamless transition from EF to RF using birgerCTRL for Canon RF.
