Hello,
many thanks for your response.
I think it is important to bring us opportunity to use new mount lenses (i mean mounts for hybrid camera). Now, the old Canon EOS mount or old Nikon mounts won't bring us new lenses.
I know backfocus for Fuji X mount is very small but if you consider removing the 2"- M42 11mm ring on the ASI485MC, i think an adaptor could easyly be made and screwed directly on the camera body.
With that kind of adaptor, i could use quite good lenses with F/D 0.95 ratio. This would be really cool for wide array sky survey videos.
You must decide to plan that kind of adaptor !
