Canon C300 Mark II EF-Mount Overview
The EF-mount Cinema EOS C300 Mark II Camcorder Body with Dual Pixel CMOS AF features a Super 35mm CMOS. This provides faster and more accurate autofocusing to assist users when operating with small crews. Canon’s Log 3 Gamma supports 14 stops of dynamic range.
The EF lens mount on the EOS C300 offers compatibility not only with Canon’s existing broad range of DSLR lenses but also with their line of EF-mount CN-E cinema prime and zoom lenses. The Super 35mm sensor is paired with the Canon DIGIC DV 5 image processor, which uses an innovative method of breaking out red, green, and blue data to enable color performance on a level that would otherwise require three separate chips. The camera records up to 4K DCI resolution video to CFast 2.0 cards. For more flexibility to adjust your image during postproduction, the camera also offers Canon’s Log gamma mode, which results in excellent tonal reproduction in the highlight and lowlight regions of an image, and an expanded dynamic range.
In terms of connections, the camcorder features two 3G-SDI outputs, timecode I/O, and genlock input BNCs. The body has a modular design that can either be stripped down completely or be built up using the included handle, 4″ rotating LCD unit with full controls, grip, and thumb rest.
Firmware v.184.108.40.206.00 adds the following features:
- Canon Log 3 achieves a dynamic range of 1600% with 14 stops of dynamic range, and can be ideal for middle end users that have a limited budget for post-production, and need quick turnaround.
- A reduction in the dark noise level when shooting in Canon Log 2 mode. Streaking and black sun spots have been reduced in all modes by changing the CMOS sensor control.
- ACES 1.0 Output via SDI/HDMI
- Magnify Function During REC
- Additional lens functionality is now available with the Cine -Servo 50 to 1000mm, Cine-Servo 17 to 120mm, Compact-Servo 18 to 80mm, and Dual Pixel Focus Guide has been added to the EF mount Canon Cinema prime lenses. Please note that you may need to also upgrade the firmware in your lens to access this functionality.
Dual Pixel CMOS AF Technology
It provides continuous AF (Autofocus) function for all autofocus lenses, using Dual Pixel CMOS AF technology. A new AF Lock setting also lets you change the image framing while holding the desired focus. This feature is ideal for users who regularly shoot with smaller crews, who shoot moving subjects, or who want smoother, more natural-looking autofocus.
Dual Pixel CMOS AF technology features a CMOS sensor that consists of an array of pixels that each feature two separate photodiodes. By continuously comparing their outputs during AF mode, phase-difference autofocus helps ensure non-blurred images and smooth focus transitions even when the talent and/or camera are moving. The new feature places a high priority on maintaining sharp focus while providing a natural, smooth autofocus movement with select Canon EF lenses – including newer-generation STM lenses – which offer even smoother and quieter operation.
