The Sony FX3 and Sony FX30 look almost identical in terms of body and handling. Still, there are fundamental differences that can strongly influence your choice. Think of sensor format, low light performance, depth of field, and flexibility in lens options. In this comparison, we break down the key points so you can confidently choose the right camera for your next production.
Sensor format: Full-frame vs APS-C
The most defining difference between the FX3 and FX30 is the sensor format.
- Sony FX3: full-frame sensor Delivers that signature cinematic look with natural depth of field. In addition, the FX3 performs better in low light situations thanks to its larger pixels. This makes it ideal for shoots in challenging lighting conditions, such as evening scenes or locations with limited artificial light.
- Sony FX30: APS-C sensor Slightly less sensitive to light, which means you’ll need to use higher ISOs more quickly in darker environments. You sacrifice some depth of field, but in return you gain flexibility. APS-C lenses are generally more compact and accessible in terms of choice.
Screen and handling
On paper, the FX30 has the edge: its LCD screen features 2.36 million pixels versus 1.44 million on the FX3. This difference mainly comes down to the processing power required for full-frame. In practice, the FX3 offers a more balanced workflow, especially when working regularly in demanding lighting situations.
When it comes to ergonomics, both models are nearly identical. They share the same compact body, button layout, and active cooling system. Whether you’re a solo shooter or part of a larger crew, both feel instantly familiar.
Slow motion and crop factor
Both cameras record in 4K up to 120fps, but there’s an important difference in crop:
- FX3: 1.1x crop at 4K 120fps. A 35mm lens effectively becomes 38.5mm – still highly versatile.
- FX30: 1.6x crop at 4K 120fps. A 35mm lens turns into a 56mm. This can be limiting if you often rely on wide shots or dynamic movement sequences.
For productions where slow motion plays a crucial role, the FX3 clearly has the advantage.
Connections and workflow
Both cameras are equipped with professional XLR inputs via the top handle, allowing you to capture high-quality audio with ease. The difference lies in the additional features:
- FX3 comes with timecode in/out, an essential tool for multicam setups, studio productions, or any project where sync is critical.
- FX30 lacks timecode, making it slightly less suited for complex workflows.
Lens options
Full-frame lenses (Sony E-mount) are generally larger and heavier. These lenses can also be used on camera bodies with an APS-C sensor, but you’ll need to take the 1.5x crop factor into account (example: 24mm > 36mm).
Which one will you choose?
The choice between the Sony FX3 and FX30 isn’t just about price – it’s about the context of your production.
- Choose the Sony FX3 body if you need maximum low light performance, more creative control over depth of field, and work in professional multicam or studio productions.
- Choose the Sony FX30 body if flexibility and compactness matter more to you, if you want to use a broader range of lenses, and if you’re looking for a budget-friendly alternative without compromising workflow.
