The main disappointment I have with my LX is that for a 'Pro' camera the fastest flash synch speed is 1/75th second whereas my ME Supers synch at 1/125th - I do a lot of outdoors fill-in flash -- even on my K10D it is only 1/180th second fastest synch speed -- other makes can manage 1/250th easily ! Also, the LX has the 'sticky mirror' syndrome where it sticks up if the camera has not been used in a while and it needs to be fired several times before the mirror becomes 'instant return' again.
