<b>Full-frame Creativity</b>Beautiful 4K HDR imagery from oversampling a 6K Full-frame Exmor R sensor with 15+ stop dynamic range and Dual Base ISO. Capture the impossible with the world's first full-frame Electronic Variable ND and Fast Hybrid AF that will track your subject with unprecedented speed and accuracy.<b>4K capturing with oversampled 6K Full-frame Exmor R sensor</b>The camera's full-frame 6K sensor provides superb recording in DCI 4K, Ultra HD and HD resolutions. Powerful image processing with debayering and down-sampling ensures image quality beyond the limits of conventional Super 35mm sensors. The back-illuminated CMOS image sensor also uses Sony's Exmor R technology for improved sensitivity and noise reduction. Compared to a 4K Super 35mm sensor, the FX9's 6K sensor has over twice the surface area while providing a wider angle of view and shallower depth of field.<b>15+ stops dynamic range</b>FX9 offers an exceptional 15+ stops of dynamic range - beyond the normal range of human perception - allowing for unprecedented creative freedom in color grading and post. Camera operators can concentrate on framing the scene they want while relying upon the FX9 to capture every nuance and detail using either 4K 4:2:2 10-bit internal recording or 16-bit RAW external recording. In grading, colorists can find color and detail beyond the normal viewing abilities of the camera operator to create a final image that exactly portrays the mood of the scene.<b>Dual Base ISO of 800/4000</b>FX9 features a base sensitivity of ISO 800, providing the optimal dynamic range for typical documentary applications such as shooting outside or in brightly lit interiors. A secondary high base sensitivity of ISO 4000 excels in low light conditions such as early morning and evening shoots while maintaining superb image quality. ISO 4000 is also ideal whenever you're using slow lenses. Combining Dual Base ISO with the camera's electronic variable ND Filter provides superb creative control in almost any shooting environment, with truly next generation responsiveness to changing conditions.<b>World's first electronic variable ND filter for full-frame sensor</b>Realize even greater creative control with Sony's unique built-in electronic variable neutral density (ND) filter - a world first for professional full-frame camcorders. Set to Auto or adjust filter density manually in smooth increments from 1/4 to 1/128 as you shoot, for perfectly exposed images without affecting depth of field as lighting conditions change. Use higher density settings with a slower shutter speed for breathtaking artistic effects.<b>XAVC 422 10bit recording on XQD media cards</b>Depending on the project, the FX9 has a selection of recording formats. XAVC-I with 422 10bit quality at a highest 600Mbps in 60p. XAVC-Long for more longer recording time in smaller file size. Also, the traditional MPEG HD codec is also available....
