First Look: LCW Helmsman USB Follow Focus For Canon DSLR Cameras.
Here is a BTS Quick Take on the new Helmsman USB Follow Focus from Light Craft Workshop. It worked with our Tokina 28-80mm f2.8 Zoom and should work with most Canon EF mount AF lenses. It is not the smoothest operator on the block but I suspect that it will react differently for each lens depending on the lenses AF capability, focus throw, etc. It has a remote start/stop button and lets you use the digital zoom function on the Canon cameras. This will be a great addition to anyone with a jib arm or in need of a wired remote focus and trigger. We are now selling them here on Wide Open Camera. The Helmsman retails for $460 US.
