The FUJIFILM GFX 50S features a 43.8x32.9mm CMOS medium format sensor: a product of Fujifilm's rich history, cutting-edge digital technology and extensive knowledge of medium format film cameras. Boasting an effective resolution of 51.4 million pixels and paired with high-performance GF lenses, the sensor delivers superior tones and sharpness that will impress professional photographers shooting in the world of commercial, fashion or landscapes.
Both the shape of the light-gathering micro-lenses and the processing from the photodiodes have been optimized to achieve a high level of sharpness and broad dynamic range. The lowest native ISO sensitivity of 100 and the 14-stop dynamic range, achieved with 14-bit RAW data, delivers high definition images in a variety of conditions with notably rich skin tones and intricate foliage detail.
The FUJIFILM GFX 50S sports the X-Processor Pro image processing engine, capable of drawing the very best out of the 51.4 megapixel sensor. Its advanced processing accelerates and optimizes the camera's performance in a variety of areas including stunning color reproduction with Fujifilm's unique Film Simulation modes, in-camera RAW conversion to the 8-bit TIFF format, accurate contrast AF, quick startup time, and minimal shutter release time lag and shooting intervals between frames.
The FUJIFILM GFX 50S uses the G Mount, which has a mount diameter of 65mm, flange back distance of 26.7mm and minimum back focus distance of 16.7mm. It uses as many as 12 electronic contact points for sending and receiving data, plus it supports the use of a wide variety of lenses and accessories. The short back focus distance, made possible because of the Fujifilm mirrorless system's structure, affords greater freedom in lens design to contribute to the development of fast, compact and high-performance GF lenses while preventing vignetting to deliver edge-to-edge sharpness.
