As luck would have it I have just bought a triple extension model last Friday,and very good it is too . It has geared focus on the back through a nut on the right ,the left is for locking , it also has some swing ,no left to right and no rise and fall , after using it for a few days it is a very easy camera to operate ,the screen is a lot brighter than my sinar P2 and all in all is a very aestetic camera . the only small snag is the lack of geared movement on the front rise and fall ,this makes slight changes with a heavy lens a touch interesting , all in all if you were looking at a very usable camera for not a lot of money I would certainly consider the triple extension
