Baader M48 Spacer Ring – MPCC III to Canon EOS T-Ring
Attach the MPCC Mark III directly to a Baader protective Canon EOS T-Ring using the Baader M48 Spacer Ring. This spacer ring will maintain the proper optical distance of 55 mm. Allows the full 48 mm unvignetted aperture to be employed instead of 42 mm to match the Canon T-Ring.
