I have a this item and EFW, ASI1600mm PRO. as I know, back focus distance of those item is 17.5 + 20 + 6.5 = 44mm.
but, I have to make the back focus distance of 55mm. how can I make it?

Katherine Tsai – :
Are you going to connect EFW and EOS lens?
Then you do not need to reach 55mm back focus since the back focus of EOS lens is 44mm.

I bought this to attach to a FotodioX Pro Lens Mount Adapter to Sony Alpha so I can use my Sony Alpha and Minolta lenses with the ASI1600. It works but now I can’t remove your adapter from the FotodioX adapter for storage. Any ideas? I assume the silver pin on your adapter should be pushed in to remove the adapter but it won’t budge.

Katherine Tsai – :
Yes, the silver pin should be pushed in to remove the adapter.

Hi there. I would be interested in a similar adapter that provides the means to connect to the electronic contacts of the EF lens. Any suggestions? Thanks

I have a Fotodiox adapter that allows my Sony Alpha a-mount lenses to work on a Canon EOS camera body. Would that adapter work in conjunction with my ZWO 1600mm Pro, EFW and your “EOS Lens Adapter for EFW” to allow me to use my Sony Alpha lenses with the 1600mm?

Does this adaptor work with the ASI120 camera and a normal manual filter wheel? Do I need another extension ring?

Sorry it cannot, the back focus will be too long

John – :
Hello, will this combination work with the ASI174mm camera? I understand the backfocus is similar to the 1600, however is not mentioned here. Thanks.

Katherine Tsai – :
Does the T2 11m ring on your 174MM can be unscrewed?
If it can be unscrewed, then this comnbination will work.

My apologies if this has already been answered – I’m considering buying the ASI1600MM Pro (6.5mm) with 8 position EFW (33mm) on a Canon lens (55mm requirement), but this adapter is 17.5mm, which makes it 2mm too deep? Is there a Canon adapter of 15.5mm depth, or have got my sums wrong?

Sam Wen – :
our EFW is 20mm thick, 6.5+20+17.5=43.5 which is very close to Canon back focus distance

James – :
I have the ASI178MM-Cool and the 8 position EFW, I’d like to attach a 50mm f1.8 or a Samyang 135 F2 to the filter wheel and camera, would this adapter be comparable with this setup for wide-field work?

Hi, Sam. I recently bought ASI 1600 Pro with EFW, it is an amazing camera, great thanks! I am thinking to use the camera with my Canon EF-S lenses. My questions: 1.when you will have the EFW adapter in stock (the site shows out of stock)? 2. does this adapter work with both EF and EF-S Canon lenses? 3. Does holder ring (78 mm) properly fits ASI 1600?
