Hi
I just thought you may like to see the Gamma Tests and Moire tests I did yesterday on the C300 (ef) Not the most exciting of videos I know but it gives an idea of the different Gamma settings and also the lack of moire the camera produces on fabrics that you would think would cause a problem. Also no noise in the blacks. V Good!
