Shooting with the BNCR has been interesting. Most of the time it resides on a gear head or a moviola dolly. At first the belt driven mags gave us the most problems. It is a beast. I saw the dailies for the first two days. It looks quite amazing with the super baltar lenses we are using, 1", 2", and 3".
Overall our arri 2b techniscope has been the most demanding. The director and dp can never decide how exactly yo use it. In the blimp, outside the blimp, with the tobin motor, with the arri crystal sync motor, stedicam, handheld. I sit there and wish for a pl mount on it many days.
AC's get spread thin shooting with thest camera, especially using short ends.
