Hey Folks!


I might have a 3D shoot coming up. I own two analog Chrosziel Fox Units both with HEDEN M28VP. When I set it up so that both receivers are controlled by one unit they work perfectly synced BUT when making really fast pulls, like from infinity to the closest focusing distance they are off a few milliseconds. Could it cause problems like on fast pulls?


By the way, does anyone know why that is? I mean the motors are the same, the difference in serial number is 190... ;-)

This might be painfully too late but I've done extensive 3D stuff and other than maxing the torque there isn't really a way to get any two lenses to track perfectly, especially on a beamsplitter as the vertical lens has much more resistance. I typically adjust the torque on vertical lens to be a step stronger (using cmotion) and it gets it pretty close, but it is never perfect.
