"VK has discussed hacking a new setting for remote focus control by patching audio through the mic in to control the focus distance. (Not working yet)"
@Blackout yes and no. It would work but as the 14-140 and 20mm pancake are not 'direct' focus rings (they are controlled by software in the camera) the Follow Focus may not be as 'responsive' as you would like.

Also non-direct focus rings on lenses tend to be exponential (ie: they focus +- quicker if you turn the gear faster).
That said- for using this gear you can easily pick up a few used Nikon prime lenses - very inexpensive on ebay ($50-$500) and have direct focus.
oh the gambles we take to save a few $. I was burned by the "new, improved W96 LEDs" a little while back, buying before the reviews came in and we found out the weren't so improved :) i think i should learn a lesson.
As you can see, this is first batch. I do not see any reason no to believe this seller in his claims that play is less than RJ FF. Plus it is more adjustable, more easy to install/remove and also lighter.
