The ZWO Canon EOS filter drawer allows you to easily connect ASI cooled cameras to Canon EF-mount lensesand hasa built-in2″ filter holder.

It is compatible with all ASI cooled cameras with 17.5mm back focus distance (except ASI GT series): 1600/294/183/071/533/2600 (excluding Duo series cameras).

Note:Thread interface is M42 x 0.75 -While theincluded M54 male to M42 female adapter will in theory allow you to use the filter drawer with full-frame cameras such as the ASI2400/ASI6200, this is not recommendedas the free aperture is smaller than the sensor diagonal of 43.3mm. Additionally, the free aperture will cover the guide sensor of ASI2600 Duo series cameras.

The spare filter holders for the new V2 M42/M54 filter drawers are compatible with the EOS/Nikon filter drawers.

If using non-ZWO filters, make sure they fit the measurements below:
