The LX has the widest unassisted metering range ever - then and now, at EV -6.5 to EV 20. The IDM (off the film) metering - including flash mode, gives it the best aperture priority auto exposure - including other brands. Unlike all others past and present it will reliably meter ultra long exposures in aperture priority mode while continuously monitoring the scene for changes in light - extending or curtailing accordingly.
As others have pointed out, the build quality is second to none - including other brands.
Oh and by the way, it is one elegant looking design . . .
