Cool thanks! Does the 1200 use the same focus setup as the 900....where there's a handle on the head left, and a set of two nested knobs on head right? The two knobs on mine apparently are set up for locking the head's vertical travel and for focus adjustment. The lock (outer knob) doesn't seem to lock, and the focus (inner) knob doesn't move the lens stage any......

Thoughts? Things to check?
