The Sony PMW-F55 CineAlta 4K Digital Cinema Camera features an 8.9MP Super 35mm image sensor. The F55 is capable of capturing 4K, 2K, and HD resolutions in a variety of formats internally. The F55 is among the first digital motion picture cameras with a global shutter. This completely eliminates motion skew and other rolling shutter distortions. Sony has designed the F55 as the foundation of an exceptionally versatile and modular system.
Many digital sensors can match and even surpass traditional motion picture film for resolution and low-light image quality. With approximately 14.3 stops of dynamic range, film has maintained an advantage over most digital sensors. The F55’s exposure latitude is rated at 14 stops of dynamic range, offering a truly film like rendering of highlights and shadows. Moreover, the F55 incorporates the same color filter array technology used in Sony’s flagship F65. This provides a colour gamut that is even wider than motion picture film.
Onboard 4K recording requires high data rate recording media, and the F55 will use Sony’s newly developed SxS PRO+ memory cards. A 128GB card will provide enough space for approximately 40 minutes of 4K video in the XAVC Intra 422 format. SxS PRO+ cards will also allow onboard recording of 2K video at up to 180 frames per second (requires a free firmware upgrade) as well as SStP 4:4:4 at 440 Mb/s when set to RGB.
