Hi to all. I own a lot of Leica, and voigtlander equipment, including a new M7 starter kit. Of them all, my 2 year old MP and 35mm summicron asph are my favorite. But they are not my most reliable: the MP is back in NJ at Leica because it's shutter button got progressively stickier when pushed...not smooth at all. And now my Summicron is going back because of it's focussing: it always had a very light damping, but on the M7 it slightly binds, making it impossible to focus precisely before it binds then skips the point I am trying to set it at(I have 12 lenses of different makers, covering 50 years, and not one other does that on the M7 or my M5). What is the point of all this? My voitlander lenses(21mm skopar, 28mm ultron) and R2a keep working perfectly...not a burp. It just proves that any piece of equipment can need service, and why there is a warranty.
