I have a 40mm f/2 but i don't know if its CL or CLE? how can i tell. the serial number is on its face. Also the lettering on the face where it says the name and info isn't painted white. its black and blends with the rest of the lens.

Serial number on the face means a CL lens. CLE has it on the barrel down by the mounting. There's not a massive difference in quality between the two lenses.
