"Leica hits the sand" story........................................not! Seriously, giving my tiny a CL and lenses their due attention and a little cleaning here and there, I find the little roller inside the top lip of the camera body - the one that activates the viewfinder focus mechanism - is actually starting to wear the mating rim on the lenses. The tiny 40mm "C" lens has a different configuration machined into the respective area on the lens "cam" (?) and isn't as affected or so noticeable. But the 50mm and 90 mm "M" lenses - just where this little roller hits the brass part of the lens focusing mount - feels decidedly sharp and "wire edged" by comparison to the rest of the lens "cam". Is this normal? At some point, won't the wear be noticeable enough to cause a teeny error in focusing indication? The tiny roller feels pretty heavily spring-loaded and rolls quite smoothly but the force it's putting on the mating part of the M lenses is kinda un-nerving. Comments? Is this something not worth worrying about? Can I - should I - get the M lenses modified or cut down to match the tiny C lens? Is that a dumb idea? The area affected appears to be the only un-plated brass parts visible on the lenses and brass certainly isn't the hardest material on earth. Thanks in advance for any insight. Rgds, Tom Hodge
