There are a number discussions concerning the reliability and build quality of the Leica R6 here, and elsewhere, on the web. These are mostly ten to fifteen years old and many of the problems reported seem in the realm of "infant mortality", that is, manufacturing defects which appeared in new cameras and presumably were corrected under warranty and were avoided in cameras produced later. At least ten years have passed now, and I post this to ask how well the Leica R6 has held up with time. Early defects, if any, will have been corrected and user's experience/comments will reflect camera durability and quality of design. Early problems often mentioned are mirrors becoming detached, frozen shutter speed knobs, and seizing of the DOF lever. Are these persistent problems or just early failures with new cameras? I am eager to read responses here. I have a nice R6 that I'd like to take with me to Europe. I'd prefer the lighter weight of the R6 but will bring a Leicaflex SL if there are reliability concerns. TIA all.
