The Sony FX3 and FX30 share many of the same high-end video features, but the FX3 is positioned as the superior camera in Sony’s cinema lineup. However, whether the FX3 is better than the FX30 depends on how you define "better" in the context of your filmmaking needs. Let’s break down the key areas where the FX3 excels and where the FX30 might still be the smarter choice.

1. Full-Frame Sensor vs APS-C Sensor

The FX3 has a full-frame sensor, while the FX30 uses a Super 35 (APS-C) sensor. This impacts:

• Low-light performance – The FX3’s larger pixels and dual native ISO (800 & 12,800) allow it to capture cleaner images with less noise in dark environments. The FX30 has dual native ISO (800 & 2500), which helps, but it still struggles in extreme low-light conditions.
• Depth of field – The FX3 produces a more cinematic shallow depth of field, making subjects pop with smoother background separation. The FX30 requires faster lenses to achieve a similar look.
• Dynamic range – The FX3 handles highlights and shadows better, giving more room for color grading in post-production.

Verdict: If you shoot in low-light environments or want the cleanest possible image quality, the FX3 is the better choice. But if you primarily shoot in controlled lighting conditions, the FX30 still delivers impressive results.

2. Netflix Certification and Professional Use

The FX3 is Netflix-approved, while the FX30 is not. This means that if you want to shoot Netflix-compliant productions, the FX3 is the clear winner.

However, for independent filmmakers, YouTubers, and content creators, Netflix certification may not matter. The FX30 still delivers professional-grade video quality that works for commercials, short films, and web content.

Verdict: If you plan to shoot content for Netflix or other major streaming platforms, the FX3 is required. If you don’t need that certification, the FX30 remains a solid choice.

3. Built-In Audio and Professional Workflow

The FX3 comes with an XLR handle, offering two XLR/TRS inputs for high-quality audio recording directly into the camera. The FX30 requires an additional purchase of the XLR handle to match this capability.

For run-and-gun filmmakers and documentary shooters, the FX3’s out-of-the-box XLR integration makes professional audio setup easier and faster.

Verdict: If you need built-in pro audio solutions, the FX3 is the more convenient option. If you can live with external recorders or third-party audio solutions, the FX30 can still work.

4. Cost vs Performance: Is the FX3 Worth It?

The FX3 costs over twice as much as the FX30. This begs the question: Is it worth the price?

• The FX3 offers better low-light, dynamic range, and professional features, but for many filmmakers, the FX30 delivers 90% of the same video quality at a fraction of the cost.
• If budget is a concern, the FX30 allows you to invest in better lenses, lighting, and accessories while still getting professional video capabilities.

Verdict: If you want the best full-frame quality and professional workflow tools, the FX3 is worth the investment. However, if you prioritize value and don’t need a full-frame sensor, the FX30 is arguably the smarter purchase.

Final Take: Is the FX3 Truly Better?

The Sony FX3 is technically the superior camera, offering full-frame image quality, Netflix certification, and built-in pro audio features. If you’re working on professional, high-end productions, the FX3 is the better long-term investment.

However, the FX30 provides nearly all the same features at a significantly lower price, making it an outstanding choice for independent filmmakers, budget-conscious creators, and those who don’t need full-frame video.

Which one is better? That depends on your needs. If you want the best image quality and professional workflow, the FX3 is the winner. If you prioritize value and versatility, the FX30 holds its own as an incredible alternative.
