The Differences Between the Sony FS7II and the Sony FX9
Sony's professional-grade cameras have always been the go-to for videographers and cinematographers alike. The company is known for its cutting-edge technology and exceptional image quality. The Sony FS7II and Sony FX9 are two of the most popular cameras in the Sony lineup. Both the FS7II and FX9 are professional-grade cameras, but how do they differ? What are the advantages of one camera over the other?
In this article, we will take a closer look at the Sony FS7II and the Sony FX9 and compare their features, specifications, and capabilities. We will also highlight the improvements that Sony made to the FX9 to make it a better camera than the FS7II.
Design and Build Quality
Both the Sony FS7II and FX9 have a similar design but differ in weight, size and ergonomics. The FS7II is a bit smaller and lighter, making it ideal for handheld work or a gimbal rig. It also has a retractable EVF which is great when transitioning from tripod to handheld shooting. However, the FX9, on the other hand, has an integrated viewfinder, making it a good choice for run-and-gun shoots because it reduces setup time.
Both cameras feature a modular design, allowing for customization with third-party accessories. Another notable feature is the built-in 4 channel audio recording, which is ideal for documentary work.
Sensor and Processor
The Sony FS7II and FX9 both feature Super 35mm-sized sensors, a common size used in the film and broadcast industry. The difference lies in their resolutions. The FS7II has a 4K output resolution, while the FX9 boasts a 6K full-frame sensor that can scale to 4K.
The FX9 also utilizes a newer and faster image-processing system, the X1, versus the FS7II's XAVC codec for image processing. In addition, the FX9 utilizes Sony's electronic variable ND filter made famous in the Sony Venice camera. The electronic ND adjusts ND filter density without changing iris settings, making it a great tool when shooting in environments with varying light conditions.
The FX9 also adds support for Sony's dual base ISO, originally from the Sony Venice camera, which means you can shoot in low-light environments without extensive noise from the video. And its full-frame sensor delivers four times higher readout speeds than its predecessor, making the camera's autofocus faster and more accurate.
Video Recording
Both cameras are capable of recording DCI quality footage at up to 60p, and up to 180fps in HD. However, the Sony FX9 uses a 10-bit 4:2:2 internal recording format, which captures richer and more accurate colors than the FS7II's 8-bit 4:2:0 format. Another improvement over the FS7II for the FX9 is the inclusion of a RAW output via the RF mount. RAW output is invaluable when post-processing, as it allows for uncompressed, high-quality image files.
Autofocus and Image Stabilization
The Sony FX9 has a new autofocus system, with up to 561 phase-detection points, offering faster and more reliable subject tracking. The DFS (Dual Focus Sensor) system also allows for larger coverage of the frame compared to the FS7II's autofocus system.
Image stabilization is another aspect where the two differ. The FS7II uses a traditional optical image stabilization technology, offering image stabilization of up to 4.5 stops. The Sony FX9, on the other hand, utilizes an electronic image stabilization system which is much smoother, with faster response times and the potential to offer up to an incredible 6 stops of image stabilization.
Price
There is no getting around it, the Sony FX9 is a more expensive camera than the FS7II, but you do get more for your money. With its modern and faster autofocus system and improved picture processing, the Sony FX9 is worth the extra investment for those who need the additional capabilities.
Conclusion
The Sony FS7II and Sony FX9 are both excellent cameras with unique features that cater to different styles of shooting. The FS7II is a great camera for run-and-gun situations, delivering excellent image quality with easy setup and operation. While the Sony FX9 is the clear winner in terms of superior features and functionality, with its 6K full-frame sensor recording up 10 bit 4:2:2 footage internally, while still being able to provide 4k RAW to an external recorder.
If professional videographers are looking for more value for their money, Sony's FX9 is the way to go. But if you're looking for a reliable, easy-to-use camera that delivers excellent image quality for projects with more limited budgets, then the FS7II is a still solid option.
