tom collicott – November 8, 2017:

Hi. I have ASI1600 and ASI 290. The 1600 has 6.5mm spacing to sensor, where the 290 has 7.5mm spacing. I dont think I would want to use the 290 with the camera, but do you think it would be OK with 1mm error? ALso, maybe it would be better if this spacing was standardised as 6.5mm for all ASI models.
Thanks Tom

Frank Feger – August 21, 2017:

Hi Sam,

the flange focal distance of the Canon EF mount is 44.0 mm, the distance between the EF flange of the adapter to the T-mount flange of the adapter is 26 mm to 33 mm. Shouldn’t the camera then have a back focus distance of 11.0 mm to 18.0 mm?

Kind regards

Frank

Kurt – July 5, 2017:

Actually, thinking about the above idea, you could leave the 48mm filter adapter as-is, and use a step down ring if you want to use a 1.25″ filter.

Kurt – July 5, 2017:

Would you consider offering an additional camera side piece with a C-mount thread (1″-32tpi) and 1.25″ filter holder? A T->C adapter won’t work as it becomes too long to focus. Lot’s of folks out there would LOVE to have this to use with their C & CS mount cameras and NV gear! It would also work with your Nikon lens adapter. Thanks!

Hi. Is there a way to mount this on a dovetail etc? I.e. does it accept some sort of screw or similar? I see a silver part on one side, but I can’t figure out what it is, it doesn’t quite look like a screw.
