Reader Zygimantis writes in and shares a link to the Fotga DP500II Follow Focus which is an updated version of the DP500. Like the DP500 it sports the marking disc, two adjustable hard stops, and reversible gear. The new DP500II (version 2) sports an improved gearbox with which they say has very minimal baclash, and an adjustment button for different levels of tension. [Thanks Zygimantis]
