The GFX100 is the first in its class to sport a 102-megapixel back-side illuminated image sensor, in-body stabilization and a hybrid autofocus system with phase detect pixels covering nearly 100 percent of the image sensor. According to Fujifilm, the AF system is 210 percent faster than the contrast-detect system used in the GFX 50R.
It’s also capable of recording 4K (4096 x 2160)/30p video at 400Mbps–another medium-format first. You can apply film simulations during video recording as well as output a 10-bit, 4:2:2 signal through HDMI to an external recorder. The camera supports Fujifilm’s F-Log profile (Rec 2020) and there are both microphone and headphone jacks.

The camera offers a native ISO range of 100-12,800 (expandable to 50-102,400) and 16-bit RAW image capture.
You’ll enjoy 5.5 stops of image stabilization along 5-axis thanks to the camera’s in-body stabilizer. Fujifilm suspended the shutter unit with four springs to minimize shutter shock and keep those 100-megapixel files pristine.
