For some reason I was under the impression when I got my GL2 that you could toggle the focus wheel to being a zoom wheel also. Pretty sure that's not the case. Anyone know of some kind of zoom wheel accessory, or if any of the remotes have anything like that? I'm terrible with the zoom rocker and wish I had a little more control.

You guessed right there, the manual focus ring does not double up as zoom. You can zoom with the grip rocker, the little handle zoom or the remote control.
The grip zoom has 4 speeds, which can be accessed through the CAMERA SET UP submenu (variable, low, medium and fast), 3 speeds for the handle zoom (low, medium and fast), the zoom speed on the remote control cannot be adjusted.
I much prefer the rocker zoom over a zoom ring, as it would be impossible to achieve a good result on the 20x full zoom range via the zoom ring.

Cheers, Gerd

10 hour shoot this last weekend. 2 x performances of a World Premiere of a Chorale - I would have died for a ZOOM ring.
