Image quality

We've seen the X-T100's 24MP APS-C CMOS sensor before on the X-A3 and X-A5 and expect very good results. As mentioned earlier, this sensor uses a Bayer color filter rather than X-Trans, but at this resolution the differences are minimal.

It's important to note that Raw cannot be used at the Low (ISO 100) or High (ISO 25600/51200) settings.

Key takeaways:

  • The X-T100 produces excellent JPEGs with vibrant color and plenty of detail
  • Fujifilm is pretty aggressive with JPEG sharpening, though you can turn this down if you want to
  • At high ISOs the X-T100 hovers near the top of its class
  • The X-T100 allows you to save several stops of highlight detail by shooting Raw at base ISO and brightening them in your favorite editing software, and has in-camera DR modes to do the same thing in JPEGs (although not as precise)

Our test scene is designed to simulate a variety of textures, colors and detail types you'll encounter in the real world. It also has two illumination modes to see the effect of different lighting conditions.

The X-T100's JPEGs look great, with vibrant color and good detail capture. The default sharpening setting is a bit over the top, though you can dial this down on the camera.

The camera maintains a lot of detail at both middle and high sensitivities, helped by extremely good noise reduction that does well to preserve detail. Raw image quality at high ISOs give the X-T100 a slight advantage over its peers.

Dynamic range

To understand a camera's dynamic range, we do two things. First we look at how tolerant of being brightened the shadows of an image are. Since our test scene only has a narrow dynamic range, we increasingly underexpose it, so that it represents increasingly deep shadows. The X-T100's sensor impresses, with low noise levels that keep up with the top cameras in it class.

The other half of our test is to compare a base ISO image that's been brightened to an image shot at higher ISO, with both given the same amount of light. This shows the degree to which the sensor's output benefits from being amplified, to overcome the noise floor. There's essentially no difference between shooting at base ISO and brightening versus shooting at a higher sensitivity. The main benefit of the base ISO + brightening combination is that you can retain several stops of highlights which would be otherwise lost if you used a higher sensitivity.

The X-T100 offers a dynamic range enhancing mode for JPEG shooters, that take advantage of this behavior. By setting the DR mode to 200% or 400% you can get up to two stops of additional highlight data, by essentially lowering the amount of amplification being applied.
