ZWO 2″ Filter Drawer for Canon EOS Lenses (with male M42 connection for the camera) (one 2" filter holder included)

This ZWO 2-inch Filter Drawer with 26.5mm thickness has been independently developed by ZWO. It includes an M42 * 0.75 male thread on the camera side and a female Canon EOS type bayonet mount on the lens side, and it is suitable for 2" filters (the filter holder has got an M48 * 0.75 female thread).

The main idea of a filter drawer is to use it with a colour camera where there is usually no need for lots of various filters, usually just a few filters need to be swapped between sessions. One of these would normally be either a UV/IR-cut off or light pollution filter (CLS, UHC etc) and the other filter would be a narrowband, i.e. H-alpha or a Dual or Triple Band filter.



1. It’s compatible with all ASI cooled cameras with 17.5mm back focus length (except the ASI GT series, like the ASI 1600GT or ASI183GT).

2. It’s compatible with all ZWO 2” filters, including the duo-band filter, narrowband filters, IR-cut filter, etc.

Below requirements fir the filter cell must be met while using a 2” filter from a third-party. (See specifications for the filter cell on the below drawing. )

3. The double strong magnets create stronger hold, easier installation and pulling out of the filter holder.

4. The camera side connection is via a M42*0.75 thread. You can also use a M54M-M42F adapter to connect the filter drawer to a full-frame ZWO camera (i.e. ASI6200MC-PRO or ASI2400MC-PRO)
