I'm having trouble to get the focus kit to work, the small one is just too small, and the bigger one (5509.28) is just barely fitting, with the clear plastic sleeve deformed when the black plastic strips are in the grooves of the sleeve. Has anyone got this to work? This is on a 5dmkII, and the reason I want to focus is to use it while filming.
Any hints or ideas would be appreciated!
