Hi, I recently bought a 12504 Lens hood from Keh to use on my 35mm Summicron ASPH Ver.1. Problem is I'm having a hard time removing the (rounded) lens cap when the said hood is attached. Just wondering if there is a specific lens cap for the 12504 cap?
Bonus question, my 12504 is engraved with "Leitz Werzlar Germany", any idea what year was this made?
Thank you.
