EOS R6 Mark III Replacing regular eyecup with long eyecup

dewynkoop — Tue, 27 Jan 2026 14:40:37 GMT

I want to replace the eyecup with a long eyecup. Does the R6 Mark III use the same shape and connection points as the R6 and R6 Mark II?

If they are compatible; how is the eyecup removed from the R6 Mark III, as it doesn't appear to have the tiny screws to hold it in place.

The screws are hidden under little covers that are held on by sticky tape.

It has been reported on line that the JJC extended eyecup does work with the R6MIII.

Any idea about how to remove these nasty little covers held on by sticky tape appreciated - missing the JJC extended eyecup I´d used at my R62.

Thank´s in advance

They pop off using a pin or sewing needle.

Succeeded, thank´s again. These cap´s are indeed increadibly thin, other than they appear they are.

And it's a bonus that JCC supplies four screws with the new eyecup. I only needed two but they obviously know what a pain it is to remove the originals.
