The Canon EOS C300 Cinema EOS Camcorder Body (EF Lens Mount) takes what professionals love about DSLR filmmaking – access to a vast selection of widely available lenses, a large sensor that facilitates a shallow depth of field, and portable operation with a modular, compact camera – and addresses its shortcomings. That means that unlike DSLR cameras, this Cinema EOS camcorder is designed inside and out for professional cinematographers capturing motion pictures that will stand up to rigorous post-production processes.

The EOS C300 features an EF mount for compatibility not only with Canon's existing broad range of DSLR lenses, but also with the burgeoning line of EF Cinema Zoom and Prime lenses. These lenses are designed to match up perfectly with the 3-perf Super 35mm-size CMOS sensor that Canon developed for this camera. Like the camcorder, these lenses (sold separately) were developed specifically for digital cinema, with engraved markings on angled surfaces in meters and feet and uniform front diameters for easy lens switching without having to reconfigure a matte box or follow focus gearing.

The Canon Super 35mm sensor is paired with the Canon DIGIC III 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. Recording HD formats to CompactFlash cards as the XF codec – at the highest level a 50 Mb/s, 4:2:2 MPEG-2 format – the C300 records motion video that reduces the jagged edges and Moiré patterns that can plague video with 4:2:0 chroma subsampling and lead to post-production challenges.
