We needed a system that could be used with ambient light, as it is less tiresome for the actors who sometimes spend days and days in our studio. High speed (for more accurate capture of fast movements) and high resolution, in particular for the facial motion capture, were also very important. The F-Series cameras are the only cameras that offer all of these attributes within the same system. There is simply no alternative system out there today if your objective is to obtain the highest possible quality.
