ZWO CANON EFW/M42 ADAPTER

This ZWO short adapter allows to connect your Canon EF lenses to ASI cameras with an M42 female thread and 6.5mm back focus, or the ZWO EFW filter wheel.

The adapter is the combination of 2 parts:

• The first has a female Canon bayonet adapter to a male M60 thread (optical thickness of 10.5mm)
  

• A female M60 thread to male M42 thread (optical thickness of 7mm)

The optical thickness of the whole adapter is 17.5mm.

Not compatible with EF-S lenses.

To fine-tune the lens-sensor distance, the adapter include 4 round plastic shims with a thickness of 0.1mm, 0.2mm (x2) and 0.5mm.
