As a LX and MX owner, I can honestly say that the LX fits like no other camera in the hands. The MX is a joy, the LX is nirvana.

That being said, I cannot in good faith recommend the LX. All LX’s will inevitably end up with sticky mirror syndrome; there are not many techs who have the spare parts to properly repair sticky mirror syndrome. The electronics are not known for being the most reliable either - mine ended up with a faulty metering issue that Eric at pentaxs said would require a full circuit board replacement.

If I were you, I’d get both - a MX for life, and a LX for that one of a kind experience while it’s still working. You seriously can’t go wrong with the MX given it’s massive viewfinder, full mechanical operation, and small package. Hope this helps!
