Hey everyone. I recently joined the Leica screwmount camera club. I shoot them on a new Voightlander body though. My question is about wear to the screw threads. I have more than one lens. I'm always very careful when I screw them on and off, no rushing, forcing, or overtightening. If I exercise care when mounting and unmounting a screwmount lens, should I have concern for wearing down the threads? Can I assume that the metallurgy of the threads can handle that wear, or should I keep lens changes to a barest minimum? Sorry if this sounds like a silly question, I am mostly used to using bayonet mount lenses.
