The GFX 50S from FUJIFILM is a unique medium format mirrorless camera that is highly versatile and distinctly portable. At the heart of the GFX camera system is the 43.8 x 32.9mm 51.4MP CMOS sensor, which pairs with the X-Processor Pro image processor to produce files with extremely wide dynamic range and high resolution, as well as an extended sensitivity range of ISO 50-102400 for working in difficult lighting conditions. The sensor's large form factor also achieves a unique three-dimensional look with especially smooth tonal and color transitions. Beyond this, the sensor and processor combination also avails the ability to work in a variety of aspect ratios common to traditional large and medium format film cameras
