Fujifilm quietly released a special edition of the Fujifilm X-T4, and nobody noticed. Specifically, it’s the X-T4 ES (“Extended Spectrum”), which is a full-spectrum infrared camera. Digital camera sensors are sensitive to light outside of what humans can see, and a filter is added to the top of the sensor to block those wavelengths so that you get normal-looking colors. The Fujifilm X-T4 ES is an ordinary X-T4, just without the infrared filter over the sensor, allowing the camera to capture invisible light, which dramatically transforms an ordinary scene into something dreamlike.

I’ve wanted to try infrared photography for decades. A long time ago I shot one roll (I believe it was Ektachrome EIR, but I don’t remember for certain); however, none of the frames turned out—mostly because I really didn’t know what I was doing way back then. More recently, I learned that many Fujifilm cameras have some IR sensitivity, so I made several infrared photographs with a non-converted camera; however, that was only a tease.

The problem with modern infrared photography is that (with a few exceptions) it requires you to ship out your old gear to have an expensive and invasive procedure performed in order to remove the IR filter. There are a couple of places that will do it, and at a few different times I strongly considered sending out my old X-T1 to be converted to full-spectrum. You can also buy one that’s already done, but it will either be a used model with a roughly $500 premium, or a new model with that same premium and without a warranty. Two years ago I suggested that Fujifilm should offer an IR camera, and now they have, so I bought it!

The Fujifilm X-T4 ES is not the first infrared camera made by Fujifilm. The first was the S3 Pro UVIR in 2006, followed by the IS-1 (infrared version of the FinePix S9100) in 2007, then X-T1 IR in 2015, then GFX100 IR in 2020, and finally the X-T4 ES in 2024. However, the X-T4 ES is the first made available to the general public, as the others were specifically for “forensic, scientific, and cultural preservation applications.” Fujifilm very quietly released the X-T4 ES only on their website and with almost no promotion. Nobody even noticed it! Well, almost nobody—the camera was sold out within about a week. I’m not sure how many copies were produced—whatever the number, they were gone very quickly. I think it goes to show that there is a demand for such a camera, and Fujifilm should do something similar soon, but have more units available for purchase.

Yesterday a Fujifilm X-T4 ES arrived at my doorstep. I’m very underprepared, and excitedly waiting for some infrared filters to arrive in the mail (you need various filters to control the light to achieve different outcomes) within the coming week; however, I was surprised to learn that my old color filters for B&W film photography work for infrared. Also, unfiltered full-spectrum pictures can be quite interesting, too. I have so much to learn, and a ton of experiments to do, but so far I’m thrilled and amazed by the results—there’s a ton of potential!

I’ve only captured a small number of photographs with the new camera, and just right around the house—nothing even remotely series. The general rule of thumb that I have seen online is that IR pictures require significant editing (including color channel swaps) to get good results, particularly for color images. Of course—you know me—I’m interested in straight-out-of-camera pictures that don’t require editing, so my goal is to create Film Simulation Recipes for use with the full-spectrum Fujifilm X-T4 ES. I have a long ways to go, so it will likely be awhile before I publish anything. With that said, the pictures below are all unedited camera-made JPEGs that I’ve captured with my Fujifilm X-T4 ES, so maybe it won’t take so long afterall.
