Sony FX5 First Look: 5K Open Gate, Internal RAW & Triple Base ISO Explained

The Sony FX5 is Sony's new compact full-frame Cinema Line camera, built around a 16.6MP stacked Exmor RS sensor and a BIONZ XR2 processor with a dedicated AI unit. The headline features are 5K60 Open Gate (3:2) capture, internal X-OCN RAW recording, a triple base ISO system (800, 4000, 12800) with 15+ stops of dynamic range, and high frame rates up to 4.5K120 and FHD240. At Videoguys Australia it comes in two configurations: the FX5 Body Only at $7,849, and the FX5 with XLRH2 Top Handle at $8,849. Both are available to pre-order now, with stock expected around August 2026. Here is what actually matters about the camera, and which option is right for you.

What is new about the Sony FX5?

The FX5 takes the compact, run-and-gun body that made the FX3 a favourite and pushes it much closer to Sony's high-end Cinema Line. The core change is a newly developed 16.6MP full-frame stacked Exmor RS CMOS sensor paired with the next-generation BIONZ XR2 image processor, which now includes an integrated AI processing unit. In practice that means faster readout (less rolling shutter on fast pans and quick subjects), smarter subject recognition for autofocus, and AI-assisted white balance.

Just as important is the format flexibility. The FX5 records 5K60 Open Gate in a 3:2 area, which gives you the full height of the sensor to reframe, stabilise, or deliver vertical and horizontal cuts from one take. Add internal X-OCN RAW and this is the first camera at this size and price to bring genuine Cinema Line workflow tools into a body you can shoulder or gimbal all day.

Why does the 16.6MP stacked sensor matter?

A stacked sensor separates the light-gathering layer from the readout circuitry, so data comes off the chip much faster. For video shooters that translates to three real benefits: dramatically reduced rolling shutter distortion, higher sustainable frame rates, and cleaner high-ISO performance. The 16.6MP resolution is a deliberate choice. It is enough for oversampled 4K and true 5K delivery, while keeping the individual photosites large for better dynamic range and low-light sensitivity.

The BIONZ XR2 processor and its AI unit handle the heavy lifting for autofocus. Sony's subject recognition now tracks people, animals, and vehicles with more reliability, and the AI-powered auto white balance helps keep colour consistent when you move between mixed lighting, which is exactly where solo operators lose time.

What can it record? 5K Open Gate and internal RAW

This is where the FX5 stops feeling like a hybrid camera and starts feeling like a cinema tool. The standout modes are:

  • 5K60 Open Gate (3:2): uses the full sensor area for maximum reframing latitude and vertical or anamorphic workflows.
  • Internal X-OCN RAW (LT, C1, C2): Sony's efficient RAW codec recorded straight to the card, no external recorder needed.
  • High frame rate: up to 4.5K at 120fps and Full HD at 240fps, with 4K 240p promised in a future firmware update.

Recording lands on dual CFexpress Type A / SDXC card slots, so you can run relay or backup recording. For a body this size, being able to capture 5K Open Gate RAW internally is a serious leap, and it is the single biggest reason to look at the FX5 over an FX3.

How good is it in low light? Triple base ISO explained

The FX5 introduces a triple base ISO structure of 800, 4000, and 12800, a step up from the dual base ISO on earlier Cinema Line bodies. A base ISO is the setting where the sensor delivers its cleanest, widest dynamic range. Having three of them means you get an optimised, low-noise starting point across bright daylight, interior, and near-dark conditions rather than pushing gain and adding noise. Combined with 15+ stops of dynamic range, the FX5 holds highlight and shadow detail in the kind of high-contrast scenes that trip up smaller cameras.

Backing this up is 5-axis in-body image stabilisation, which makes the FX5 genuinely usable handheld, and a redesigned menu system with streamlined controls aimed at operators who need to change settings fast on set.

Body Only or XLRH2 Top Handle: which should you buy?

Videoguys stocks the FX5 in two configurations. The difference is not the camera, it is the audio and rigging package that comes with it. Here is the quick verdict: choose the Body Only if you already own a cage and audio setup or shoot mostly on a gimbal, and choose the XLRH2 Top Handle version if you record professional audio and want the optional viewfinder path built in from day one.

  FX5 Body Only FX5 with XLRH2 Top Handle
Price $7,849 $8,849
XLR audio inputs Not included Yes, 32-bit float via XLRH2 handle
Top handle Not included Included
Best for Gimbal / solo shooters with existing rig Doc, event, and interview work needing pro audio

If you shoot interviews, documentaries, events, or anything where clean, professional sound matters, the XLRH2 Top Handle kit is worth the extra $1,000. The 32-bit float XLR inputs alone can save a recording that would otherwise clip or come in too low, and having the handle from the start means one less accessory to source. If your audio is handled elsewhere or you build custom rigs, the Body Only keeps your outlay lower.

Frequently asked questions

How much does the Sony FX5 cost in Australia?

At Videoguys Australia the Sony FX5 Body Only is $7,849 and the FX5 with XLRH2 Top Handle is $8,849, both including tax. Both configurations are available to pre-order, with stock expected around August 2026.

What is the difference between the Sony FX5 and the FX3?

The FX5 uses a new 16.6MP stacked full-frame sensor with a BIONZ XR2 AI processor, and it adds 5K60 Open Gate capture, internal X-OCN RAW recording, a triple base ISO system, a larger 3.5 inch multi-angle screen, and dual CFexpress Type A slots. In short, it brings high-end Cinema Line features into the compact FX-series body.

Does the Sony FX5 record RAW internally?

Yes. The FX5 records X-OCN RAW (LT, C1, and C2) internally to CFexpress Type A cards, so you do not need an external recorder to capture RAW.

What is triple base ISO on the FX5?

Triple base ISO gives the sensor three optimised, low-noise sensitivity points: 800, 4000, and 12800. Shooting at or near a base ISO delivers the cleanest image with the widest dynamic range, so the FX5 stays clean from bright daylight through to near-dark scenes.

Which Sony FX5 option should I buy?

Choose the Body Only if you already have your own audio and rigging or shoot mainly on a gimbal. Choose the XLRH2 Top Handle version if you need professional 32-bit float XLR audio and want the top handle and viewfinder path included from the start.
