Know before you buy
Yes, this adapter is designed to fit standard Canon EOS bayonet mounts, making it compatible with both EF and EF-S lenses.
The adapter provides a fixed 17.5 mm extension. This is specifically engineered to match the back focus requirements of ZWO ASI1600 cameras when used in conjunction with a ZWO Electronic Filter Wheel.
While it is designed to integrate with the ZWO EFW, you can connect it directly to your ASI1600 camera if the total back focus distance remains within the required range for your specific imaging setup.
No, this adapter is strictly for Canon EOS (EF/EF-S) mounts. It will not fit Canon RF mirrorless lenses.
No, this is a mechanical adapter only. It does not provide electronic communication between the camera and the lens, so you will not be able to adjust the aperture through your imaging software.
Yes, the CNC-machined aluminum construction is highly durable and provides a rigid, stable connection. However, for very heavy lenses, we recommend using a lens support ring to prevent any potential strain on the camera or filter wheel connection.
