Utilizing a large, 43.8 x 32.9mm 51.4MP CMOS sensor and an improved X-Processor 4, the GFX 50S II is capable of delivering high-resolution, 14-bit stills with 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 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.
