Hey Guys
I am a Focus Puller and Loader from Melbourne Australia and I have 3 BFD's, with M1 and Heden motors.
I have taken these on many shoots all over Australia, and never had any negative feedback about the system. DOP's love it because I just hand over the Iris unit and they can happily pull iris, while i am still pulling focus. (This option is avaiblable with the Preston but costs $6000 ish, which is similar to a BFD kit). Other Focus Pullers love its simplicity. Producers love the cost.
These are ticks in all the right boxes in my opinion.
