This is a new, slightly improved version of ZWO's popular EFW-EOS adapter. The old and new versions are identical, except for the side release pin in the old version that has been replaced by a larger, easier-to-use side button. It allows you to connect small format ZWO cameras with a ZWO 1.25"/31mm/36mm filter wheel to a Canon EF (full frame) lens. Please see the full compatibility list below to ensure this adapter is correct for your camera.
There are four Canon lens to ZWO camera adapters:
- ZWO Filter Drawer for Canon EOS Lens # FD-EOS - best for color cameras with use of a 2" filter
- ZWO Canon EOS Lens Adapter for 2" Electronic Filter Wheel # EFW2-EOS - best for large format monochrome cameras that use a 2" filter wheel
- ZWO Canon EOS Lens Short Adapter for Electronic Filter Wheel # EFW-EOS-II - best for small format monochrome cameras that use a 1.25"/31mm/36mm filter wheel (this product)
- ZWO T2 Thread to Canon EOS EF-Mount Lens Adapter for all ASI Cameras # EOS-T2-II - best for connecting most ZWO cameras without the need for quickly changing filters
Compatibility with Canon Lenses:
This adapter is compatible with Canon EF (full frame DSLR) Canon lenses only. It is not compatible with EF-S (crop sensor DSLR) lenses or Canon mirrorless lenses.
Compatibility with ZWO Cameras:
This ZWO adapter allows you to attach a Canon EF (full frame) EOS lens to select ZWO cameras that have a backfocus of 6.5mm via ZWO's Electronic Filter Wheels (EFW). This includes all cooled (Pro model) cameras that have a 4/3" sensor or smaller. It has a female EOS bayonet mount on the lens side and a male T/T2 thread on the other side which connects to the EFW. The EFW, in turn, connects to the ZWO camera.
Compatibility with ZWO Filter Wheels:
- ZWO 8-Position Electronic Filter Wheel for 1.25" or 31mm Filters # EFW8-125/31
- ZWO 5-Position Electronic Filter Wheel for 1.25" or 31mm Filters # EFWMINI
- ZWO 7-Position Electronic Filter Wheel for 36mm Unmounted Filters (Version II) # EFW7-36-II
- This product cannot be used with 2" EFWs and you will need EFW2-EOS if using a 2" filter wheel.
