ZWO Canon EOS Lens Adapter for 2" EFW Filter Wheel - EFW2-EOS Jansale A 1/4" to 3/8" adapterThe ZWO EFW2 EOS adapter was designed by ZWO in order to connect a Canon EOS EF lens with a ZWO EFW2 2" filter wheel. This short adapter takes up 11. 5 mm of back focus and can only work with ASI cooled cameras with 12. 5 mm back focus, such as the ASI16200 and ASI2600. The thread of the interface is M54 and so therefore does not fit the 1. 25" EFW electronic filter wheels.
