Canon lens to filter wheel

Just looking into this myself (though for different camera options). The SX filter wheel is 37mm so not sure this is going to work. Best I can find as an alternative so far is an EF to M48 adapter (10mm), then the Askar 5-in-1 filter drawer (18mm), then onto your camera. Back focus on the SX 825 seems to be 17mm +/-1mm so depending on your filter thickness you may be ok (EF lenses need 44mm backfocus so 3mm filter would get you bang on 44mm).

If you mean something like the photo below there is ZWO adapter for that.

I had seen this set up but it says ZWO only I did email firstlight optics they did send link to this but never mentioned that it would work on SX equipment? Might need to email them back.

Note that you should keep the total backfocus for Canon EF lenses to 44mm (flange to sensor distance), or you will have a real problem focusing.
