Micro Four Thirds vs. Full-Frame: Which is the Better Sensor? (MMM#40)

Greetings all,

Madeline here, back with the 40th entry in The Movie Minute! For the very first entry of 2026, we’ll be diving into a comparison of camera sensors within the equipment we use!

Think of a camera sensor as being like the retina in our eyes- it’s what tells our brain what we’re seeing. A camera body is essentially a box with a sensor- the lens is what makes the camera able to see things. With DSLRs, a mirror reflects light coming through the lens onto the sensor, while a mirrorless camera has the sensor exposed directly to the lens.

There’s multiple different types of lenses, but every camera body has a certain type of lens mount that determines what type of lens can be used, and it often corresponds to a specific type of camera sensor.  For example, the Panasonic Lumix GH5, which is my go-to camera, uses a Micro Four Thirds (MFT) sensor. The sensor’s small size offers some advantages, such as more efficient bitrates that often translate into smaller file sizes, saving space for storage. MFT cameras also have great in-body image stabilization, which makes it an excellent choice for shooting run-and-gun. However, crop factor might not make MFT cameras an ideal choice for wider shots, or for low light settings without maximizing ISO (leading to more image noise).

On the other hand, there’s the full-frame sensor, which is used on our more advanced cameras such as the Sony A7IV. While bitrates are higher compared to MFT, full-frame sensors have some notable advantages, such as better performance in low-light conditions and less image noise due to cleaner ISO. Depth of field is often shallower depending on the lens though, so MFT might be a better option when wanting to maximize the use of bokeh (the visual appeal of blurred background objects that are out of focus) in your shot.

But it’s important to note that when it comes to the right sensor type, bigger does not necessarily mean better. The best type of camera sensor depends on the project and your needs. For a lot of the projects we shoot, the GH5 is more suitable for b-roll as well as an additional angle for run-and-gun interviews. But for other situations such as main interview angles and still photos, we use full frame cameras such as the A7IV and the Canon EOS R, as well as the Sony FS7 for more formal sit-down interviews.

Overall, the sensor of a camera is one of the most crucial things to think about when preparing for a shoot. While both MFT and full frame sensors have their pros and cons, it’s important to think about what you’re filming, as both are great for different types of shots and situations. For us at Poor Bear Stories, we often make use of both types as it allows us a great degree of flexibility that will enable us to produce high quality stories.

And that’s all for this entry in The Movie Minute. Wishing you all the best, and see y’all in 2! – Madeline
