Shoot Low light films without flash or tripod. So it flips the image over again. The RX10 in particular wins for its low-light video recording capabilities, something the manufacturer has proven to do very well in recent years thanks to such high ISO management. These pellicle mirrors reduce the amount of light travelling to the film plane or sensor and also can distort the light passing through them, resulting in a less-sharp image.
