Hi, I'm planning to attach my Rokinon 135mm (Canon version) to the ASI533MC PRO for some wide field views. So, I bought the New EOS-T2 Adapter and waiting for it to arrive.

I'm wondering about the back space focus if I need to attach any extra axtender. I want to use the the 11mm female to female t-thread adapter in order to attach my 1.25" L-eXtreme filter directly to the camera. So, not sure if I should just attach the EOS Adapter to the 11mm adapter and that's it or not.

Canon flange is 44mm. ASI533 has 17.5mm back focus (?).

If it's this adapter then you can not use any extenders.

But I believe it has space for 2" filter.

So you think I can't use this adapter in order to attach the 1.25" filter?

Yes you can use it. I've used it just for this propose smile.gif. I've succesully shot with a Tamron 90mm macro (Canon mount) and an L-eXtreme 1.25" filter and also with an UV/IR blocking filter.

Did you mean I can attach the 11mm adapter then attach the EOS-T2 Adapter ?

 

So, it will be like this: 

ASI533MC -> 11mm T-Thread Adapter (1.25" filter inside) -> EOS-T2 Adapter -> Rokinon 135mm lens

 

Correct?
