Thanks John for your insights. I have a couple of relatively decent 2/3"
lenses that could be mounted on the 101 via an adapter, but I think that you
are right that the controls of the Z1 can be adapted to, and overall the
package (or perhaps better the coming V1) is superior to an ersatz pro
camera like the JVC.
