I had reserves about buying this as another astro friend said their ZWO / EF adaptor was very questionable.
However, I believe ZWO recently re-designed their adaptors and this one is anything but questionable! The quality is perfect. It fits snug with the EF connection locking in place nicely and easy to unlock. The filter drawer is similar to starizona / Baader filter drawers withmagnets to hold the drawer in place securely.
This drawer holds my Astronomik UV and Narrowband filters and ZWO 533 with no problems. This drawer provides the perfect 44mm back focusing distance needed for EF lenses without any need for spacers or extras

This is just about the only way to have a Canon EF lens reach focus properly with a ZWO camera *and* be able to use filters. However... (no fault of FLO!) the filter drawer in this is completely different to the regular ZWO filter drawer for use with a ZWO camera and telescope. I was really hoping they'd be the same, but they're not - and not compatible. This means I have to unscrew my filter each time I want to swap back and forth. Why ZWO didn't make the drawer the same is beyond me, but there you go - something we have to live with to be able to take filtered images with EF lenses! Well made item, and a satisfying click when the lens attaches, with no wobble. Expensive, but of good quality.
