Fujifilm X-T5 ISO Range (Still Images)

The Fujifilm X-T5 has a total ISO range when shooting photos of 64 to 51,200. But it’s not quite that simple. That’s because, like many modern cameras, there’s a native ISO range and an extended range. So let’s break that down.

The X-T5’s native ISO range is ISO 125 to 12,800. Native ISO refers to the natural sensitivity of the hardware (in this case, the sensor).

The X-T5’s extended ISO range goes down to ISO 64 on the low end and up to 51,200 on the high end. Put another way, these are the ISO settings that are available in the extended ISO range: ISO 64 / ISO 80 / ISO 100 / ISO 25,600 / ISO 51,200. ¹ The extended ISO range refers to settings beyond the sensor’s natural sensitivity and where in-camera software adds a boost.

Fujifilm X-T5 ISO Range Sample Images

Here are some photos I’ve shot with the X-T5 throughout the ISO Range. In the shots below, I’ve included both native ISO and extended ISO ranges, arranged sequentially. I’ve also posted, separately, some more high-ISO sample images taken with the Fujifilm X-T5.

There are a few things worth noting here.

• You can click on each image for a full-size version.
• The versions you see embedded in the page here are generated from straight-from-camera JPG versions.
• By default, the X-T5 adds noise reduction to enhance high-ISO JPGs. When shooting these, I’m using the camera’s default of 0. (You can also choose in settings along a sliding scale from -4 to +4.) So what you’re seeing here are the versions after the X-T5 has applied noise reduction in-camera. That’s why I’ve included links in the caption for each image to open the original JPG and RAW files. The RAW files, in particular, will give you the most accurate view of the sensor’s performance before processing.
• But even then, there’s another layer. As standard procedure, the X-T5 embeds a JPG preview image in the RAW file. That preview image has the same processing as the JPG versions. And that is what shows when you first open the RAW file. So if you want to strip back to the actual RAW image, make sure to regenerate the thumbnails (aka previews) in your RAW image editor.

ISO Range When Shooting Video

I’m focusing here on the ISO range when shooting photos. The available ISO range when shooting video is mostly the same, with a few key differences at the edges.

The native ISO of the X-T5’s video shooting is ISO 125 to 12,800. The extended range goes up to 25,600.

Things Worth Knowing

• Using ISO 25,600 and ISO 51,200 involves quite a lot of processing power. The result is there’s a noticeable slow-down in the camera when shooting at those as you wait for it to finish before moving on. It’s quick–less than a second or so–but definitely noticeable if you’re shooting a rapid sequence.
• If you plan to use different software for addressing high-ISO issues when editing, you’ll be much better off using RAW files than processing on top of the already-processed JPG versions.
• The extended ISO range settings aren’t available all the time. To enable them, you need to turn the sensitivity dial to C. I’ve posted a guide to accessing the highest ISO settings separately.

1. I’ve seen some tech spec pages for the X-T5 put the lowest setting at ISO 80. That’s incorrect–it’s ISO 64.[↩]
