Sony PXW- FX9

With the PXW-FX9, Sony introduces its new top model for mobile use with a modern 5.9K full-frame sensor and a Fast- Hybrid- Autofocus.

The FX9 is similar to its successful predecessors PXW-FS7 and PXW-FS7M2 . But with the autofocus system, for example, it uses also technology coming from the DSLM Alpha series.




Features and Design

The heart of the new Sony FX9 shoulder camcorder is the 5.9K full-frame EXMOR R sensor.

While the Sony FS7- series still uses an EXMOR CMOS sensor in 4K resolution, the FX9 uses the more light-sensitive, back-exposed R variant according to the Sony DSLM Alpha series. In 4K or FHD mode, the sensor works with oversampling, what means that the full sensor area can be used in both modes.

Recordings are made on XQD cards in XAVC Intra, XAVC Long or MPEG HD422. 4:2:2, 10bit color sampling is internally possible up to 4K. Via 12G- SDI a 16bit- RAW - signal can be recorded externally. Until further notice, however, the 16-bit- RAW outputs only as a S35 Crop. Interestingly, ProRes is no longer available.

Sony specifies the dynamic range of the FX9 with 15 f-stops. The Dual- Base- ISO - System enables ISO800 (Low) or ISO4.000 (High).

The possible video formats result from the two recording modes: 4K (UHD ) and 1080p. These can be read out either as full sensor readout (with oversampling) or as S35 with crop.



4K in 60p/ 50p is initially only available as S35 Crop. A later update will add the possibility of oversampling. Please note, that this mode uses only a 5K area (FF Crop horizontal 5K), so not 100% of the sensor is read out in this case. Also a 4K-DCI mode will be added with a later update.

Slow motion can be recorded at up to 120fps in 1080p or S35 Crop using the full sensor. 120fps in 4K and 180fps in 1080p come a bit later via update.

Based on the Sony VENICE , the FX9 also offers a new Color Science called S- Cinetone.

In competition to the successful Dual- Pixel- Autofocus from Canon, the FX9 offers a Fast- Hybrid- Autofocus whose technology comes from the Alpha series. It combines contrast and phase detection AF. With 561 AF points the FX9 is on the level of current Sony Alphas (Sony Alpha 7R IV with 567 phase detection points).

Regarding the tracking functions, face tracking (face registration) deserves special mention. This allows faces to be saved at the touch of a button. When the stored person comes back into the picture, the FX9 automatically can focus on this person.



The variable ND filter known since the Sony FS5 is also used in the FX9.

A housing image stabilization is not built in, but a gyro sensor provides frame-based metadata that can be evaluated with Sony Catalyst Prepare and Browse and used for post-production stabilization. The optical stabilisation of the lens can be used for additional support.

The lens mount is a Lever Lock E mount.

The FX9 can record up to 4-channel audio. 2xXLR and the internal microphone are available in basic setting. If the 2-channel wireless receiver (UWP-D Series) is used additionally via the flash shoe, tracks 3 and 4 can also be occupied. The XDCA-FX9 Extension Unit also allows tracks 3 and 4 to be used.

Remote applications via WIFI are already known from other Sony cameras, the new full format FX9 follows this example via CBM (Contents Browser Mobile). In addition to a LiveView of the camera image (approx. 1 second offset), camera functions can also be operated remotely via an app. These include, among others: whitebalance, ND, shutter, focus, ISO and the REC button.

Housing and handling are similar to those of the predecessor FS7 M2. The retaining tubes for the viewfinder are no longer round but square, which effectively prevents the viewfinder from slipping away. The handle has also been ergonomically improved.
