FUJIFILM Corporation announced that, in late February 2017, it will release the FUJIFILM GFX 50S(GFX 50S) medium format mirrorless digital camera, adopting a 43.8 32.9mm medium format (FUJIFILM G Format) sensor with 51.4 MP. Featuring premium design and excellent operability stemming from the highly reputable digital camera "X Series" system and the accumulation of image design technology from over 80 years of experience, the GFX 50S achieves the image quality from Fujifilm. Released with the APS-C sensor in 2011, the X Series system has earned high praise from professional photographers and photography enthusiasts alike, due to its excellent image quality and mobility across a wide range of genres including landscapes, snaps, portraits and sports photos. On the other hand, there were also many photographers craving for the release of a camera equipped with a large-size sensor with an even higher number of effective pixels, which could be used mainly in the fields of commercial and studio portrait photography, while at the same time keeping the excellent color reproduction of the X Series intact. In response to those voices, Fujifilm developed the GFX 50S and the FUJINON GF Lenses series as a system for photographers that require even higher image quality than can be covered by the current X Series lineup. Equipped with a 43.8mm x 32.9mm, 51.4 MP CMOS sensor, boasting approx. 1.7x the area of full frame sensors: Both the shape of the light-gathering micro-lenses and the processing from the photodiodes have been customized to achieve a high level of sharpness and broad dynamic range. The excellent light reception performance due to the large area of each pixel, room to spare is created in the camera's high sensitivity performance and tone reproduction, achieving high image quality exceeding that of cameras equipped with full size sensors with an equivalent number of pixels. Therefore, precise images can be reproduced down to the smallest detail, conveying the texture of the subject, a three-dimensional feeling, and even the atmosphere of the scene. Equipped with X-Processor Pro image processing engine: By using the highly rated X-Processor Pro, which is also used in the X-Pro2 and X-T2 cameras, it is possible to experience Fujifilm's acclaimed Film Simulation color reproduction with an ultra-high quality large size sensor. The Movie function also supports Full HD recording at 30p. Users can enjoy high quality video with no post-processing required by using Film Simulation modes just like they would with a still image. Compact and lightweight body with high rigidity due to the adoption of magnesium alloy: With a weight of approx. 1,230g when paired with a standard lens (GF63mm F2.8 R WR), the camera weighs approx. 60% of a medium format DSLR camera equipped with a sensor of the same size. Even when compared to a DSLR camera with a slightly smaller full size sensor, the camera comes in at almost the same weight. Overall camera body height and width have also been minimized for maximum flexibility, overturning the common perceptions regarding the mobility of medium format digital cameras.
