Sorry, folks, but I have to step in in defense of the LX

I bought a first generation one second hand towards the end of the eighties and (ab)used it for years as a photojournalist. I still have it and it still works like a charm. No sticky mirror, no repairs whatsoever, no problems, no servicing... It is just such a wonderfully versatile tool: The ultralong autoexposure, those superfast times on the other end, the mirror lockup. Pull off the viewfinder and put in on the ground or use it over head. The unbeatable TTL flash system and the super exact film advance which works backwards as well. And it is stable, rugged, rain- and dust-proof.
The MX on the other hand... Don't get me wrong, it is a great tiny thing and it was actually my very first camera. Had several of them later before I got the LX. Here are the problems I encountered (not now but 35 years ago): The flimsy film advance lever which could even malfunction. Slipping, prolonged exposure times due to problems with the spring loaded mechanics. The self-exposure lever just dying. Not to speak of the crappy motor drive with all those cast aluminium parts breaking... I ended up giving away the MX bodies to my girlfriends: Small hands and super gentle treatment. They loved it.
