EOS Rebel T7 or EOS R - Adaptor for Canon bellows and slide duplicator

[Munari]

Which adapter do I need to use the bellows and duplicator with EF and RF lens?

Yes they scan negatives or transparencies. There are a lot of them on the market, different brands, I don't think I can post a link on this forum but if you search Amazon or Ebay for 'slide duplicator' you'll find several, some of them come with their own LED light source. I have one and it works fine.

I had some 2x2 square slides and just used a light table and macro rail with my EF-S 60mm macro lens.

Just throwing it out there.  Amazon has tons of film, negative and slide scanners.  They might be a lot less cumbersome than one of the set ups above.
