That’s all well and good, but this guy wasn’t even asking about dealing with a cinema camera — just a basic XF100 camcorder. I use 3-4 of these in multi-cam productions all the time. Each cam op is using them handheld to record concerts…i.e. very dynamic shooting that requires extensive zooms for close-ups and focus pulling.
For a Canon cinema camera, yeah, I can see the need for an accurate focus pull. But with those cameras you also get the luxury of lens selection and the preciseness that only comes with a controlled, multi-take, (usually) single-camera production environment. I mean, I wouldn’t dare use a C-100 or a C-300 in my case because it’s so above my budget for one, but also above my needs as a run-and-gun videographer.
But now we’re entering a completely different topic; I just think it’s weird that someone would actually consider needing a focus puller for a 3 lb. entry level camera haha. BE the focus puller…envision it in your mind. You can do it!
