I have a separate thread with results using the filter wheel here:


https://www.cloudyni...s-ha/?hl= canon


It is very snug - in a good way - and makes a tight connection to the lens.  At least in my version.  The 135 f/2 images I show are wide open and the field looks good across the 1600 sensor.  I also show images with 15mm lens - that are not as good across the field.  But I think the connection is very solid.



Thank you Frank. Very interesting.

Hi Sergey and welcome to CN.


For the OP - I hope it's ok we are talking about this controller and not simply an adapter.  


Sergey you asked about what lenses it works with - and it works with all that I have tested:


17-40 f/4, 135 f/2, 300 f/4 IS, and Sigma 15mm f/2.8


All were listed in your lens.txt file.


All lenses seem to work fine without a separate 5V power supply.


The IS lens showed no sign of IS activity - which is fine and I didn't expect IS to work.  I think that if you put such a lens on a tripod it is recommended to turn it off anyway.


Control of the zoom would be useful for certain things if it is possible - but no big deal.  Woops - not awake yet.  The zoom isn't even motorized.  Never mind.


All in all it seems to work fine and has a solid attachment.  I can also use it with Kenko extension spacers - which isn't a surprise since it is just passing the signal through.


I went ahead and ordered a thin ZWO filter wheel for it.


One thing to test would be to see if the USB hub in the ZWO cameras can control the lens.  I assume it should work ok - and that would mean one cable to the camera and a separate short cable to the lens.  I have an old 1600 with no hub inside so I can't test.


Thanks for providing this device - it looks like a powerful addition.



Absolutely! I'm just catching up and reading this thread and your other thread and getting ready to order the controller! Thanks for all of the great info!

Yes - ASI1600mm with Samyang 135mm f/2.0 (canon EF mount), ZWO EFW mini & Baader 1.25" SHO&Lum filters.


Hi I'm new to cloudy nights and astrophotography I was wondering how did you attach a footplate to the astromechanic canon lens adapter. What is that mounting system in the image here?

The entire ring/rail system you see in that picture was purchased online from a french website named astrokraken. It's a singular 3d printed piece specifically designed to be used with the samyang 135mm f2.0.
