Rokinon Front Element: 1.13"

Rokinon Rear Element: 0.75"

Canon RF 35mm Front Element: 1.13"

Canon RF 35mm Rear Element: 1.75"

The EOS M6 hasn't arrived yet. Reproduction comparison to follow later.

The front element measuring almost identically is fascinating though. Goes to show equivalent glass equals equivalent size (and roughly similar weight). At f/1.4 on crop, you're very similar to an f/1.8 on FF that's probably not the most honest f/1.8, say f/1.89 etc, rounded down for marketing reasons...
