This year, Fujifilm has released two exceptionally good APS-C cameras. In my view, these are the best crop sensor cameras currently on the market. As more and more people get their hands on these cameras, problems relating to overheating seem to be surfacing with the Fujifilm X100V.
In a recent video from Denae & Andrew, they discuss and demonstrate how the Fujifilm X100V can potentially overheat. This camera continues with the smaller form factor of APS-C cameras, yet now offers a lot more in terms of features. The upgraded sensor, autofocus, and video features are brilliant; however, the camera doesn't seem to be managing them very well. The video demonstrates how after prolonged use, the camera can get a little hot to the touch. This is especially a problem if you're filming with it.
Companies like Sony have in the past provided firmware updates to combat these problems for their cameras. Hopefully, Fujifilm can also provide a firmware update to fix this problem. In the meantime, however, the video does offer some solutions to help prevent the camera from overheating.
Personally, I don't think this is a major problem. The main reason I think this is is because most people don't really use these types of cameras for long sessions of filming. If this were a problem on the X-T4, then one could argue its significance; however, as far as I'm aware, this is not the case.
Check out the full video to see what can cause the X100V to overheat and how to prevent this too.
