Fujifilm announced a variant version of its flagship X-T1 camera on Monday that's been tuned to capture not just visible light but a limited amount of infrared and ultraviolet as well. It's not the first camera to do so — infrared photography was popular in the film days — but it does combine a powerful modern body and lens selection with the expanded sensitivity.
IR and UV, radiation with longer and shorter wavelengths respectively than what our eyes can detect, are difficult to photograph except with specialized equipment. Ordinary glass, even the kind used in camera lenses, blocks a large amount of the UV and IR spectra. And even if it didn't, most photographers don't want their camera sensors to "see" that light, since it could interfere with the visible light image they want to capture. Consequently, most cameras have treated glass that cuts out light outside a specific range.
The X-T1 IR, however, along with a few other specialty devices, allow as much of the IR and UV range as possible. This allows for specialized imagery like capturing experiments or crime scenes lit by UV, or striking infrared shots showing a very different world than what we see every day. You can see a few examples in this tutorial.
Unfortunately, the camera isn't sensitive enough to enable night vision or heat detection — that requires even more specialized equipment. The Fujifilm X-T1 IR will be available in October for $1,700.
