As someone that started off loading mags and pulling focus on film cameras I’ve always hated pulling my own focus. It just doesn’t seem right. With today’s style of shooting whether on a RED, a DSLR or some other camera I find myself adjusting on the fly to a small monitor or EVF. I try and teach my students the ways of the focus puller but they never quite get it. That and the monitor is right there, they can just look at it and use peaking or some other digital tool to tell them it is in focus. Not really focus pulling, but it does the job.
So after a couple of frustrating follow focuses I’ve found one that works really well with DSLR style shooting. The Edelkrone Focus One had peaked my interest when it came out, but I couldn’t pull the trigger. I’ve been using it for a couple of weeks. It is nice and smooth and has solid feel. The best part was that it fits on the rails, and doesn’t protrude too far down so I can use it with a sliding baseplate.
EDIT: The only difficulty I have found is trying to get this thing wedged between camera and mattebox when using short primes like zeiss standard speeds. My old RedRock micro couldn’t do this either. ARRI wins.
