Sony FX30 Rig Setup: The Complete Build, Part by Part

The Sony FX30 is the FX3 with a Super 35 sensor at roughly half the price, and everything about rigging it is the same. The SmallRig Cage for Sony FX3 and FX30 half cage fits both. What changes is the lens plan: smaller glass, affordable matched cine sets, and a total rig weight that leaves genuine headroom on a 3 kg gimbal rather than sitting at the top of its window.

What this body gives you

The same chassis as the FX3, including ARRI-standard threads machined into the body, active cooling for long takes, and a detachable XLR handle with two full-size inputs. That last item is unusual at this price and it means usable dual-channel audio on day one without a separate recorder.

A 26 megapixel Super 35 sensor, which oversamples to 4K and produces a detailed image, with the same S-Log3 profile and the same colour science as its full frame sibling. Footage from the two bodies intercuts with essentially no work.

Dual card slots taking CFexpress Type A or SD, a full size HDMI port rather than micro, and the same menu system. If you already own an FX3, adding an FX30 as a B camera is unusually painless.

Where Super 35 changes the plan

Lenses get smaller, lighter and cheaper. The Sigma 18-50mm f/2.8 DC DN at around $550 is a constant f/2.8 zoom weighing under 300 g that covers the sensor fully, against roughly $2,448 and 700 to 900 g for the full frame equivalent. That difference lands on your budget and on your gimbal payload simultaneously.

Matched cine sets become affordable. The Sirui Night Walker S35 T1.2 Cine Set (24, 35, 55mm) at around $749 gives you three T1.2 primes with common gearing and a common front diameter, natively covering this sensor. There is no full frame equivalent anywhere near that price, which makes the FX30 a genuinely strong narrative body.

Depth of field gets slightly deeper at equivalent framing, which is easier to hold on a moving subject. On documentary work that is a practical advantage rather than a compromise, since the most common focus failure is a subject who leans forward out of a thin focus plane.

What it needs first

A monitor with false colour, for the same reason as every log camera: the rear screen shows a flat image with no way to judge it, and the error is always toward underexposure. A Osee T5+ 5.5-inch Monitor at around $110 is the cheapest honest entry and a FEELWORLD F5 Prox 5.5-inch at $170 adds the brightness that makes it usable outdoors.

A variable ND, because S-Log3 at its native ISO in daylight with a 180 degree shutter is several stops overexposed at any usable aperture. A K&F Concept 82mm Variable ND, 1 to 5 Stops at around $92 covers most conditions.

Then power and media in that order, with the same logic as the FX3: a V-mount system removes the two most common shoot-enders, and CFexpress Type A can wait behind fast V90 SD cards for ordinary work.

The rig, line by line

Everything below fits this body specifically. The total for the accessories, without the camera, is $1,066.82. Buy it in the order listed rather than all at once: each line solves one failure, and the early ones solve the failures that ruin footage rather than the ones that annoy you.

Gimbal fit, which is where this body wins

A caged FX30 with a compact f/2.8 crop zoom, a small monitor and a microphone comes to roughly 1.6 to 2.0 kg. That sits comfortably inside the working window of a 3 kg rated gimbal like the DJI RS 4, with genuine torque margin for fast moves.

The same build on a full frame body with a full frame f/2.8 zoom is 2.2 to 2.6 kg, which is at the top of that window with nothing spare. Adding a battery plate pushes it into the 4.5 kg class entirely.

This is the practical reason a Super 35 body is a better stabilised camera. It is not the sensor, it is that every lens you put on it weighs half as much, and a stabiliser cares about that far more than it cares about resolution.

The narrative option on this body

Because affordable matched cine sets cover Super 35, the FX30 is a genuinely capable narrative camera at a body price under $1,800. Add the Sirui Night Walker S35 T1.2 Cine Set (24, 35, 55mm) set, a Tilta Pocket Follow Focus follow focus at $59 and a Tilta Mirage Matte Box matte box at $102, and the front of the rig is a proper manual control setup.

What you give up compared with a Blackmagic body is internal RAW. The FX30 records 10-bit 4:2:2 all-intra, which grades well and is not a RAW file, so white balance and ISO are baked in. For a lot of narrative work that is entirely acceptable and the autofocus, cooling and audio handle are worth more.

The narrative starter and working builds on this site use Blackmagic bodies for the RAW workflow, and an FX30 substitutes into either of them cleanly if you would rather have autofocus and better battery life than editable white balance.

Audio on this body

The supplied XLR handle is a real audio interface with two full-size XLR inputs and physical gain controls, which is genuinely unusual at this price. A Sennheiser MKE 600 with Shock Mount or a Rode VideoMic NTG plugs straight into it and the camera records two proper channels.

That means the first audio upgrade here is not a recorder, it is a second source. A DJI Mic 2 (2 TX, 1 RX, Case) radio system on the subject plus the shotgun on the camera gives you two independent recordings, which is the actual insurance against a lost line.

A separate recorder like the Zoom F3 becomes worth it when you want 32-bit float, which removes gain setting entirely, or when you need more than two channels. Neither is urgent on a body that already gives you two clean inputs.

What to skip on this camera

• A full cage, since the body has its own ARRI points and a half cage adds what is actually missing.
• An external recorder, because the internal all-intra codec is good and a recorder mostly adds a screen and a power problem.
• A separate audio recorder at first, because the XLR handle already gives you two real channels.
• Full frame lenses, which will work and will throw away the main advantage of choosing this body.
• A V-mount on a gimbal build, since 800 g of power hardware undoes the weight advantage you bought.
• First party CFexpress Type A cards, when third party options at half the price perform identically in these modes.
