DxOMark published the result of Canon 5D Mark III sensor, the overall score of 5D mark III sensor is 81, before jumping to any decision please remember that the test score of DxOMark is based on Sensor RAW output, the low-light score of Canon 5D Mark III is 2293 ISO, Canon EOS 5D Mark III nearly ½ Stop better in low light conditions compared to Canon 5D Mark II (1,815 ISO).
The dynamic range score is almost same as 5D Mark II, the 5D mark III shows its improved performance behavior at high ISO test only.
Canon 5D Mark III vs Nikon D800
On sensor war Nikon D800 is a clear winner, the overall score, dynamic range, portrait color depth and low-light score is better than the Canon 5D Mark III.
A video Test done by Joe Marine, Nikon D800 sensor captures more light compared to 5D Mark II and 5D Mark III under low or High ISO settings, but both 5D Mark II and 5D Mark III have less noise at high ISO with bit flat details due to in-camera noise reduction filters.
Nikon D800 performance is excellent up to ISO 1600 the sensor captures more details compared to its competitors
At High ISO Both 5D mark III and II have less noise,
Personally I will prefer 5D mark III or II for video, Which camera do you prefer? – Nikon OR Canon – Share your thoughts with us

Canon is developing C500, a 4K resolution camera for both EF and PL mounts, the C500 will features newly developed Super 35mm-equivalent approximately 8.85-megapixel CMOS sensor, the new camera not support 4K-resolution video but outputs 10-bit uncompressed RAW data stream with no de-Bayering and also able to output quad full-HD (3840 x 2160), 2K (2048 x 1080), full HD (1920 x 1080), and other imaging options. All 4K formats can be selected to operate from one to 60 frames per second.
Press Release
LAKE SUCCESS, N.Y., April 12, 2012 – Canon Inc. is developing two digital cinematography cameras as part of its acclaimed new Cinema EOS System of professional cinematography products. Designated as the Cinema EOS C500* for use with EF-mount lenses, and the Cinema EOS C500 PL* for use with PL-mount lenses, the cameras will be capable of originating 4K (4096 x 2160-pixel) resolution digital motion imagery with uncompressed RAW output for external recording, in response to growing expectations for higher levels of imaging performance in premium Hollywood films and other production markets requiring the utmost in picture quality.
“With the unveiling of our Cinema EOS System last November to great acclaim, Canon marked our full-fledged entry into the motion-picture production market,” stated Yuichi Ishizuka, executive vice president and general manager, Imaging Technologies & Communications Group, Canon U.S.A. “To further serve the needs of Hollywood’s premier filmmakers, Canon is developing the Cinema EOS C500 and Cinema EOS C500 PL digital cinematography cameras, which deliver the added benefit of full 4K motion-image capture to the Cinema EOS System.”
The 4K imaging format is emerging as the new standard for advanced effects and post-production in Hollywood, and it is particularly important for big-budget motion pictures that include scenes compositing live-action cinematography with high-resolution computer-generated imagery. The Cinema EOS C500/C500 PL digital cinematography cameras will not only support 4K-resolution video but also outputs this as a 10-bit uncompressed RAW data stream with no de-Bayering. The cameras offer the additional versatility of being able to output quad full-HD (3840 x 2160), 2K (2048 x 1080), full HD (1920 x 1080), and other imaging options. All of these digital image source formats fully conform to established SMPTE production standards. All 4K formats can be selected to operate from one to 60 frames per second. The cameras employ a 12-bit RGB 4:4:4 signal format during 2K output, which can be selected to operate from one to 60 frames-per-second (fps) as well. If switched to a 10-bit YCrCb 4:2:2 mode, the camera can operate up to 120 fps.
The Cinema EOS C500 simultaneously records in-camera a 50 Mbps HD proxy video to a CF card that is immediately available to support offline editing. Equipped with a newly developed Super 35mm-equivalent approximately 8.85-megapixel CMOS sensor, the cameras will be compatible with Canon’s wide range of interchangeable EF Cinema and PL-mount lenses and EF lenses for Canon SLR cameras. Highly mobile and compact for filmmaking versatility, the Cinema EOS C500/C500 PL digital cinematography cameras – like Canon’s Cinema EOS C300/C300 PL cinematography cameras – provide all of the same ergonomic features, except for the rotating hand grip.
Further details regarding the Cinema EOS C500/C500 PL digital cinematography cameras – including specifications and pricing – have yet to be decided. Plans call for these new products to be launched later this year. In addition to targeting a swift launch of these cameras, Canon will continue to enhance other components of its Cinema EOS System product lineup, which is designed to contribute to the continued advancement of tools for visual expression and the development of cinematic culture.
Canon will display a prototype of the Cinema EOS C500/C500 PL digital cinematography camera at the 2012 NAB Show in booth C4325 at the Las Vegas Convention Center from April 16 to 19.
