New BIONX XRTM Image Processing Engine: Producing 8x the processing power of its predecessor.

Overheating & Video Time Limits: A crucial point, considering the issues that we know of over at Canon! There is no recording time limit when shooting in 4K 24/25/30p. With regards to 60p, Sony states that around 60 minutes is safe, dependent on room or outside temperature conditions. In 120p, you can expect to be able to film for approximately 30 minutes.
