Sony FX9 vs Sony FX3
Sony FX9 vs Sony FX3
When comparing Sony FX3 and Sony FX9, which one is better?
1. Weight Comparison
Weight is really important when it comes to cameras, since you'll have to be able to hold it for long periods of times and carry it around with you. Sony FX3 is the lighter camera at 715 g compared to the weight of Sony FX9 at 4800 g. This means that FX3 weighs 85.1% less than FX9.
Winner: Sony FX3
Regarding weight: A heavy camera can be cumbersome to carry with you and might also make your wrists hurt from handling the camera for long periods of time. Just make sure the camera you choose to buy is not too heavy when combined with your lens of choice.
2. Sensor Type Comparison
Both FX9 and FX3 use the same sensor type — CMOS — meaning that no camera in this comparison has an advantage over the other in this regard.
Winner: Tied
Regarding sensor type: Digital cameras feature two different sensor types; CMOS and CCD.
3. Internal Video Bit Depth
Both Sony FX9 and Sony FX3 has an internal video bit depth of 10 bit.
Winner: Tied
Regarding internal video bit depth: The internal video bit depth is important since it means that a camera can capture more colors or less colors compared to other cameras. 8-bit internal video is very limited, while 10-bit or 12-bit internal video recording is plenty for professionall applications.
4. Dynamic Range Comparison
Sony FX3 has the most dynamic range at 13 stopp where the Sony FX9 has 11.5 stopp, which is 11.54% lower.
Winner: Sony FX3
Regarding dynamic range: Dynamic range is the light difference from the darkest parts to the brightest. The dynamic range is measured by sources like Gerald Undone or CineD.com, and are not the manufacturer's specified dynamic range, since those values often are greatly exaggerated.
5. Lens Mount
Both the Sony FX9 and Sony FX3 use the same lens mount; the Sony E. This means that you can use the same lenses on both cameras, as long as they cover the full sensor. Full format lenses will work on all cameras with the same mount.
Winner: Tied
6. Rolling Shutter Comparison
Both cameras have a CMOS sensor with a rolling shutter. Sony FX3 is the best with the lowest sensor readout speed at 8.7 ms, while Sony FX9 has a readout speed of 22.2 ms — this result is 155.17% slower than FX3.
Winner: Sony FX3
Regarding sensor readout speed: Rolling shutter means that the sensor image is not read as a whole image ("global shutter") but instead line by line, leading to motion artifacts when a camera is moving fast, like in hand-held footage, or is filming a fast moving object, like a fan or car wheels.
7. Internal Raw Video Support
Neither Sony FX3 or Sony FX9 features internal raw video recording.
Winner: Tied — Neither have this feature
Regarding internal raw video: The ability to record raw video internally is becoming more and more common in cinema cameras, and this may or may not be an advantage depending on how you shoot. While raw offers the most flexibility, it also requires more powerful editing computers, faster memory cards and more storage.
8. External RAW Video Support
Both Sony FX9 and Sony FX3 supports external raw video recording.
Winner: Tied — both have this feature
Regarding external raw video recording: External raw video recording means that an external recorder, such as the Atomos Ninja V, can be used to record raw video using HDMI or SDI outputs from the camera to the recorder.
