In this penultimate episode of our series on Sachtler gear -- our first exposure to this legendary German company's products -- we take a peek at their follow focus unit, available separately  or as part of the complete and beautifully integrated Ace accessories kit (which also includes their matte box and base plate). At $630 for the follow focus alone, it's just over three times the price of my edelkrone FOCUS ONE, but spoiler alert: if it fits with the rest of your gear, I think it's worth it.
