Sensor Size

First off, one major difference is sensor size. In the cinema world, an APS C sensor or Super35 is standard and nothing new. In fact, full-frame cameras joining the cinema line are actually more unique. In this case, the benefit of the full-frame sensor includes less noise, a slight advantage in dynamic range and more control with depth of field. In contrast, the smaller sensor in the Sony FX30 allows for a jump in resolution.

fx3 and fx30 sensor size


Like we mentioned, the Sony FX30 about doubles in resolution compared to the FX3. Even though this is primarily a cinema camera, we also see an increase in resolution for stills. The Sony FX30 can capture 26MP images which is a massive upgrade compared to 12MP in the FX3. In terms of video, the Sony FX30 uses oversampled 6k footage to 4k rather than the straight pixel-to-pixel 4k in the Sony FX3. 


Sensor size can also determine what lens options are available. If you currently have more Sony E-mount lenses, then the FX30 would be very appealing. Vice versa, if you've invested in Sony FE glass, we recommend going with the FX3. The Sony FX30 can still use the FE lenses, just you will have a 1.5x crop. The same goes for if you use E-mount lenses on the FX3, you will just need to be in a crop mode setting but that limits 4K shooting.

Low Light Capability 

As you see from the chart above, the ISO range in the Sony FX3 is quite better than the Sony FX30 due to the larger sensor in the Sony FX3. One benefit to both cameras is dual base ISO.

Video Recording Capabilities 

The Sony FX30 comes with the same card storage options as the Sony FX3 and the capability to use large capacity cards like a CFexpress Type A and UHS-II memory card for higher recording options. One thing to consider is when shooting 4K 120p footage, the FX30 has and 1.6x crop vs a 1.1x crop in the FX3.

Camera Body Design

When comparing the physical specifications and camera design, both camera bodies are practically identical. They actually have the same dimensions with the only exception being that the Sony FX30 is slightly lighter, most likely due to the smaller sensor. For videographers looking to use an XLR handle or cage, both cameras have an optional XLR handle.

fx30 dimensions

Like identical dimensions, both cameras share the same connectivity options, featuring a full-size HDMI, USB-C charging port, Multi/Micro USB, mic and headphone ports.

For the entry-level filmmaker, the Sony FX30 is a cinema camera with professional features and more. Both cameras are incredible options, but for half the price and matching features to its full-frame counterpart, the Sony FX30 is strongly recommended.
