New Canon Super 35mm CMOS Sensor
Modeled on the Super 35mm 3-perf motion picture film standard, the Canon CMOS sensor has an active image size of 24.4 x 13.5mm. It uses 3840 (H) x 2160 (V) photosites to perform the crucial optoelectronic transformation of digital imaging. Each photosite is a generous 6.4 x 6.4 micrometers in area and each has a microlens that ensures the highest efficiency in light transfer to the individual photodiode. Proprietary technologies within the photosite simultaneously lower the image sensor noise floor while enhancing the photon capacity of the photodiode - a combination that assures superb dynamic range. The image sensor employs an innovative readout technique that delivers full bandwidth individual RGB video components without the need for any debayering algorithms. Each of these components has a 1920 (H) x 1080 (V) sampling structure at up to 60 frames. From these original video components, a 1080-line 60i format or a 1280 (H) x 720 (V) at 60P HD format are selectively derived.
Canon Log Gamma
Shooting in Canon Log mode, cinematographers can set the camera exposure value using their customary light meter practices. Canon Log is a special nonlinear transfer function embodied within the DIGIC DV III RGB video processing system. This transfer function is specifically designed to facilitate the post-production of digital images originating in Cinema EOS in a manner similar to the post-production of images digitally transferred from motion picture film (the contemporary DI process). By managing the disposition of quantization bits, Canon Log ensures excellent tonal reproduction within both highlight and low-light regions of a given digital image - maintaining a total dynamic range of 800%. These sophisticated video grading processes restructure a new digital representation achieving a sought-after creative look on a quality reference display.
Low Light/High ISO Ability
A dark and stormy night? With the EOS C300, it's no problem. The combination of sensor and image processor render an extraordinary signal-to-noise ratio and as such make shooting at high ISO (up to ISO 16000) a breeze.
Reduced Rolling Shutter and Moiré Artifacting
The EOS C300 uses enhanced signal processing to minimize rolling shutter skews and to reduce moiré artifacts. A high-speed readout significantly reduces the subjective visibility of the vertical skewing on fast-moving horizontal subjects, a typical pitfall of the CMOS image sensor neutralized by Canon technology.
Canon DIGIC DV III Image Processor
Designed and built by Canon for the highest HD RGB processing, the DIGIC DV III Image Processor uses proprietary circuits and architecture to deliver the highest image quality at the highest speeds, with low power consumption and minimal heat output. It processes the RGB representations originated in the single CMOS sensor of the camera into three channels (Red, Blue and Green) to maintain the rich resolution and clean color fidelity formerly possible only in three-chip sensor designs.
XF Codec Image Quality
To create digital files robust enough for major post-production, the EOS C300 delivers the highest image quality with its XF Codec - the same codec used by other Canon XF - professional camcorders. With 4:2:2 color sampling, image files have double the vertical resolution of color components created with 4:2:0 color sampling, minimizing jagged edges between red and blue and ensuring ample quality for chroma key compositing with green screens. Thanks to the Canon XF Codec and the EOS C300's superior resolution, original color quality and cinematic look will hold up through post-production - with results that meet or exceed the filmmakers expectations.

Geared inner focusing minimizes focus-induced changes in the angle of view, rendering focus breathing virtually zero. The 11-blade aperture diaphragms ensure smooth out-of-focus areas and beautiful bokeh - and innovative glass construction counteracts barrel expansion and contraction to avoid temperature-induced marking discrepancies. EF Cinema lenses provide markings on angled surfaces on both sides of the barrel, making it easy to read focus and aperture settings from behind or either side of the camera. Focus markings can be switched from standard labelling to metric. Control rings are designed to maintain the proper amount of resistance with consistent operating torque. EF Cinema lenses share uniform gear position, diameter and rotation angle as well as front lens diameters, enabling the film crew to quickly change to another Canon zoom or prime lens or compatible third-party accessories like matte boxes and rods without adjustments.
Designed with Filmmakers in Mind
With everything a cinematographer needs, the EOS C300 comes ready to produce. A logical layout of buttons and dials make operation simple. A lock switch turns off all controls except the recording button and function buttons. Small ridges between the buttons help prevent activating functions by mistake. A backlit display panel is great for low-light viewing. A tally lamp is clearly visible from the side or behind the camera.
Compact and Modular Design
The EOS C300 body is surprisingly small (5.24" x 7.0" x 6.7") and easily hand-held at just over 3 lbs. There is a bright 1.55 megapixel electronic viewfinder that comes bundled with a removable combination 4-inch, 1.23 megapixel monitor and control panel.
