C300

C300 is a designation used by several products across different industries. The two best-known uses are in automotive and filmmaking.

In automotive use, the Mercedes-Benz C 300 refers to a model within the C-Class compact executive car line. The C 300 name has appeared across multiple generations, typically denoting mid-range performance. Engines are generally petrol four-cylinders or V6 variants in older generations, with many markets offering turbocharged four-cylinders and all-wheel drive as options. The C 300 emphasizes a balance of ride quality, refinement, and efficiency, and is available as a sedan or coupé with various trims and equipment lines.

In filmmaking and video, the Canon EOS C300 is a digital cinema camera released in 2011 as part of Canon's Cinema EOS line. It features a Super 35mm sensor, interchangeable EF-mount lenses, and professional codecs for 1080p HD recording, along with built-in color profiles and gamma options aimed at cinema production. The C300 has been followed by higher-end variants such as the EOS C300 Mark II, which added higher resolution and expanded dynamic range, and subsequent models expanding 4K recording and workflow options. The C300 series has seen widespread use in independent film, television, and documentary production due to its portability and film-oriented feature set.
