Difference Between Sony FX3 and FX30 - Read Before You Buy

When it comes to filmmaking, Sony has made a big name for itself with cameras that deliver stunning visuals and professional-grade features. Two of their popular models - the Sony FX3 and the FX30 - have drawn a lot of attention. But what exactly sets these two cameras apart? If you’re wondering which one is right for you, let’s break it down in plain and simple terms.

Overview

The Sony FX3 and FX30 are both part of Sony’s Cinema Line, which means they’re designed for video creators who want high-quality cinematic results. While they look similar on the outside (you can use the same cage with both models), they’re built for slightly different users and budgets.

One of the most significant differences is that Sony FX3 is officially Netflix-approved for their productions, while the FX30 is not. This means the FX3 meets Netflix’s technical requirements for image quality and consistency, making it an excellent choice for filmmakers working on projects intended for streaming platforms.

While the FX30 still delivers outstanding results, it doesn’t carry this specific certification, which might be a consideration for professional creators aiming to meet industry standards.

Now when I’ve told you about this critical difference that many content creators don’t like to talk about, let’s dive deeper into the key differences and similarities.

Sensor Size: Full-Frame vs. APS-C

The biggest difference between the two is the sensor. The FX3 has a full-frame sensor, while the FX30 uses an APS-C sensor (or Super 35 format). What does this mean?

Full-frame sensor on FX3:

  • Captures more light and provides better performance in low-light conditions.

  • Offers a shallower depth of field, giving you that cinematic background blur (bokeh).

  • Has a larger field of view, which can be advantageous for wide-angle shots.

APS-C sensor on FX30:

  • Slightly smaller sensor size means less light capture, which might affect performance in very low-light situations.

  • Still delivers excellent image quality, especially in controlled lighting conditions.

  • Uses a crop factor (1.5x), so lenses appear more zoomed in compared to full-frame sensors.

Image Quality and Resolution

Both cameras shoot 4K video, but they achieve it differently:

FX3:

  • Uses a 10.2-megapixel full-frame sensor.

  • Shoots pixel-to-pixel 4K. In other words. FX3 gets video from the whole sensor without involving oversampling. This leads to faster readout.

  • Excels in dynamic range, making it ideal for capturing scenes with high contrast (e.g., bright highlights and deep shadows).

  • Designed to handle extremely low-light conditions with minimal noise.

FX30:

  • Equipped with a 26-megapixel APS-C sensor.

  • Also shoots oversampled 4K from its higher-resolution sensor, resulting in sharp and detailed video.

  • While it performs well in various lighting conditions, it may introduce more noise in low-light environments compared to the FX3.

Frame Rates and Formats

Both cameras support high frame rates for slow-motion footage:

FX3:

  • Shoots up to 120 frames per second (fps) in 4K resolution.

  • Offers professional codecs like XAVC S, XAVC HS, and XAVC S-I for high-quality recording.

FX30:

  • Also supports 4K at up to 120 fps, matching the FX3 in slow-motion capabilities.

  • Provides similar recording formats, ensuring flexibility in post-production.

Price

One of the most significant differences is the cost:

FX3:

  • Higher price tag, aimed at professionals who demand the best performance.

  • Justifies the cost with superior low-light capabilities and full-frame cinematic visuals.

FX30:

  • Much more budget-friendly, offering exceptional value for aspiring filmmakers or those upgrading from entry-level cameras.

  • Great for creators who want professional features without a professional price tag.

Build and Design

Both cameras share the same compact, rugged design, making them ideal for handheld shooting and mounting on gimbals. Here’s what they have in common:

Shared Features:

  • Built-in cooling fans for extended recording without overheating.

  • Multiple mounting points for accessories like monitors, microphones, or handles.

  • Dust and moisture resistance for shooting in challenging environments.

  • Fully articulating touchscreen LCD for versatile framing and composition.

However, the FX3 is slightly heavier due to its larger sensor and full-frame components. Both cameras are designed with filmmakers in mind, ensuring durability and functionality.

Autofocus and Features

Both the FX3 and FX30 come equipped with Sony’s cutting-edge autofocus system:

Autofocus Features:

  • Real-time Eye AF for humans and animals, ensuring sharp focus on subjects.

  • Fast and reliable tracking for moving objects, great for dynamic scenes.

  • Focus assist tools like peaking and zebras for manual focus adjustments.

They also include advanced video assist features, such as:

  • Timecode Sync: Essential for multi-camera shoots.

  • Picture Profiles: S-Log3, S-Cinetone, and HLG for maximum flexibility in post-production.

  • Dual Base ISO: Both cameras offer dual base ISO settings, allowing you to optimize exposure in different lighting conditions. However, the values are different. On Sony FX30 the base ISO values are 800 and 2500 whereas on Sony FX3 you have 800 and 12800.

  • Battery Life and Connectivity

  • Both cameras use the same NP-FZ100 battery, providing decent runtime for video shoots. For extended sessions, USB-C power delivery allows you to shoot continuously with external power.

In terms of connectivity:

FX3:

  • Includes a top handle with XLR inputs, making it ready for professional audio recording straight out of the box.

FX30:

  • XLR input is optional and requires an add-on accessory, making it less suited for advanced audio setups unless you invest in extras.

Who Should Buy the FX3?

  • Professional filmmakers or videographers who need top-tier performance.

  • Those working in low-light environments or requiring a full-frame look.

  • Anyone looking for the most cinematic results with premium features.

  • Ideal for commercial projects, music videos, and high-end productions.

Who Should Buy the FX30?

  • Independent filmmakers or beginners on a budget.

  • Content creators upgrading from entry-level cameras.

  • Filmmakers who prioritize portability and don’t need full-frame capabilities.

  • Great for travel, documentary work, and indie film projects.

Final Thoughts

Both the Sony FX3 and FX30 are fantastic cameras, but they’re built with different users in mind. If you’re chasing the best image quality, low-light performance, and have the budget, the FX3 is your go-to. On the other hand, if you’re looking for excellent 4K video quality, portability, and a more accessible price, the FX30 is a smart choice.

No matter which one you pick, both cameras will help you create stunning videos and bring your creative vision to life. Take your filmmaking to the next level with Sony’s Cinema Line. Happy filming!
