What's a good lens focusing unit?
I use lenses often to image with. I have in the past used a FLI PDF to get accurate focus and to be able to refocus easily. Unfortunately I sold that. It was very good.
I see Robofocus setups where there is a rubber belt wrapped around the lens focus ring and it goes down to a smaller wheel connected to a Robofocus.
The last Robofocus I had was great but old fashioned in that it wasn't USB but serial. Perhaps its USB now.
Any other focus units out there you could recommend?
Greg.
