Im sorry if this subject have been covered already but I couldn't find fully comprehensive answer to it.
I have Arri IIB with Tobin crystal motor and I need shoot on location under the prevailing lights. Most likely fluorescents. Some say you can shoot 25fps 50hz lights with no problem at 165 degree shutter but I have also reed that it can still produce flickering. Before I do the test I wonder if some one has already done it or knows how it is?
