Utilizing a large, 43.8 x 32.9mm 51.4MP CMOS sensor and X-Processor Pro, the GFX 50S is capable of delivering high-resolution, 14-bit stills with a 14-stop wide dynamic range as well as a broad sensitivity range of ISO 100-12800, which can be extended to ISO 50-102400. The large size of each pixel allows for more efficient light gathering, too, for smoother tonal and color transitions to produce a characteristic three-dimensional "medium format look." Also contributing to several medium format looks, a variety of traditional medium and large format aspect ratios can be used in addition to the standard 4:3, including 1:1, 65:24, 5:4, 7:6, 3:2, and 16:9.
The image processor and sensor also lend a versatile edge to the system and permit shooting continuously up to 3 fps or for recording Full HD 1080p video at 29.97, 25, 24, and 23.98 fps frame rates. Film Simulation modes, including a Color Chrome Effect to produce subtle tonality among highly saturated colors, can be used in conjunction with video recording, too, to lessen the need for color correction during post-production.
