While keeping the same Super 35 sensor as the original C100, the advanced Canon DIGIC DV4 image processor in the Mark II interpolates HD from the 4K sensor, much like the C500 processes 2K information. The camera separates the RGB output from the camera's 8.3 Megapixel CMOS imager into three individual 8 megapixel signals (as opposed to 2MP in the C100) for noticeably improved image quality. It also has a new debayering algorithm to help minimize moiré and reduce video noise even at high ISO speeds. (ISO range 320 to 102,400).
Canon has also increased the Mark II's recording capabilities with the incorporation of the MP4 format, in addition to the existing AVCHD format. Simultaneous recording of both codecs to two different cards is also supported, great for those with numerous post requirements. Both modes allow you to record to a maximum frame rate of 1080p60, with the MP4 mode also supporting Slow and Fast recording up to 60 fps.
There's a new LCD viewfinder as well, with a larger 0.45" display that tilts and accommodates a larger eyecup. The LCD panel is now a 3.5" OLED that articulates from the side (versus the top on the original C100), giving the operator more viewing options. It also includes a control joystick for menu navigation and image adjustments. Additionally, it now features a built in mic on the body, which is a frequently requested feature for reference audio when you're not using the top handle.
The C100 Mark II features wireless control and file-transfer capability. This enables remote control via smartphone or computer, and direct to FTP transfer of files. A great option for anyone in the news world that needs to get content back to edit as quickly as possible.
Dual Pixel Auto Focus is available as an optional upgrade for the original C100. Now, the Mark II includes Dual Pixel AF as a standard feature; in addition, it supports face detect AF when using the camera with Canon STM lenses.
Last, but not least, Canon has given us the ability to add a Rec709 LUT to the HDMI output while recording in C-Log - a feature requested by many.
The C100 Mark II is expected to be available in December 2014 at a street price of $5,499.
