The Sony FDR AX100 is quite a unique video camera. It’s not without its faults but having a 1-inch sensor along with 4K resolution and an unusual amount of 8-bit detail retention created a unique product. If put in the hands of a competent videographer who knows how to expose for this camera, the image quality truly is amazing (after some post-processing work to pull out the details). The greatest issue we run into with this camera is around stabilization as we enjoy not using tripods. The dynamic range is not great on this camera, unfortunately.
The 4K video codec was at 60Mbps but the new firmware allows for 100Mbps as well as some autofocus improvements. A few people have reported problems or a dead video cameras after attempting to update the firmware; it’s not clear if this was an isolated event or user error or something else.
The biggest advantage of this new firmware should be a reduction of macroblocking in complex and busy scenes.
