Ho appena preso una asi 224 questo adattatore è compatibile per usare obiettivi Canon? Ci sono anche altri adattatori per usare obiettivi EF-EFL? I filtri da 2 pollici per l’inquinamento si possono avvitare vero?

EOS-T2 adapter with the 5mm T2-extender can be used with ASI224.
EOS-T2 support Canon EF lens, not sure whether the EF-EFL is supported.
You can use 2″ IR-CUT filter with the adapter.

You can use this ZWO EOS-T2-Ⅱ with 1.25″ ZWO EFW-MINI Electronic Filter Wheel:
The EF adapter (first ring of set) is 11.5mm plus 4mm thread.
Add the 2mm T2-T2 adapter (male, box EFW-MINI) and the 0 mm M48-M42 adapter (box ASI183 Pro).
Then you get the necessary 11.5+4+2+0=17.5mm!
Mount this 17.5mm to the 20mm EFW-MINI and the 6.5mm ASI camera.
17.5 + 20 + 6.5 = 44mm Canon Backfocus

Josef Müller – :
I newly got. the Adapter and I would like to use it with my ASI2600MC pro and my Canon EF-S 18-55 lense. ZWO stated that EF-S lenses will not work with this adapter (0nly for EF Type you say). So far I tested during daylight and I can not see a problem. EF and EFS lenses both have 44 mm distance to the chip and so far I come into Focus without a problem. The only difference I see, that the EF is made for full frame and the EF-S is Made for APS-C format. Even the bionet connection is the same. Could you please explaine what kind of problem you see by using the EF-S lenses with this new fix lenght adapter? Thanks for your asap auswerten!!! Clear skies, Josef

Thanks for your feedback, if the EFS and the EF has the same distance and mount, it may be compatible with this adapter as well.

Mark William Johnston – :
I tried this adapter with a ZWO2600MC pro connected to a Canon 24-105 EF zoom lens and it doesn’t work. You cannot focus the lens because there is no electrical connection. I called Canon tech support and they said ALL Canon EF lenses REQUIRE an electrical connection so your adapter cannot work. You would have to use a lens with fully manual focus and aperture control to use your adapter. Correct?

sara.liu – :
Yes, you have to use a lens with fully manual focus.

Could you tell me why other lenses that are designed for Canon ef mounts will not work with this adapter? What backspace is needed for this adapter and a Zwo filter drawer?

sara.liu – :
Because of the back focus.
The back focus depends on the telescope.

I have the asi6200mc camera and the EOS T2 adapter. Do you have a way to use this on the 54mm thread on the 6200mc camera and get the correct back focus for the canon lenses without vignetting the image?
Thanks
Christian

sara.liu – :
It is normal that full frame camera has vignetting which can’t be eliminated, you can only deal with it in the post-processing.

Canary Astronomy – :
1º ¿Por que no son compatibles los objetivos EF-S si comparten las mismas características que los EF?, 44mm,
2º ¿En los 17.5 mm de distancia de adaptador no hay espacio para la goma de los objetivos EF-S que es lo único que los diferencia?
3º ¿Cuál es la distancia mínima que existe entre el objetivo EF y EF-S con respecto a un filtro de 2″ en su interior?
Un saludo

Hi, what is the thread size of this adaptor? Will the 2 inch Ir/UV filter fit “Inside” the unit and then the threads of the unit connect directly to the T2 camera thread independent of the filter? Or do you need to screw both ends of the filter into the imaging train? Thanks

Support@ZWO – :
Yes, 2″ IR-UV filter will fit.

I’d like to post a reply on your answer of the 17th of April 2020, which is a reply on my post of the 16th. In fact, the extend distance including the 5mm ring is 26.3 and not 26.5 as mentioned in the answer.
With best regards.

Hi all at ZWO,
I’m curious reading Q&A above.
There are many 3rd party lenses with Canon EF mount for Canon users. I guess those can be attached and used with this adapter, because this adapter is just a tool connecting ASI camera with lenses having Canon EF mount mechanically. But ZWO said “No, just Canon EF lens only” in the answers above. Could you please explain why any other 3rd party lenses having Canon EF mount can not be used with this adapter? Thank you in advance.
