Philip, as well as the unit Dennis has listed above, Scopestuff have a shorty adapter
#tass (I have one) which may be more suitable for the LX90, as it will still allow your camera to clear the forks and allows rotation of the camera to get the optimal position which the #talp may not. Baader also make an adapter which you can see in
this image . If I were to buy again I would probably pay a few extra dollars for the Baader unit.
