My 50mm Summicron is in Germany right now for servicing because of oil in the Aperture blades. I'm from Manila, it cost a lot to send my lens to Germany. My question is how do I prevent a similar event from happening? what is the best aperture setting for storing the lens to prevent Oil in the aperture blades? Do I store it wide open or the other way around? Thank you.
