Tony Northrup has recently released 2 videos, stating that the Fujifilm X-T4 has a serious overheating issue. So much so, that he called the X-T4 “flawed”. I will share both videos down below.

Balbo42 was curious about it and tested the X-T4 overheating by himself. Turns out he could not back it up. Here is what he says:

• Tony says the X-T4 overheats badly in video (in his video he calls the X-T4 “flawed” because of that)
• potential buyers are of course scared by that, and might not buy X-T4 after such a negative review
• he says that Tony ends up recommending buying a used Fujifilm X-T3, and Balbo42 points out that Tony’s video is sponsored by KEH, which sells used gear
  [FR-admin: I don’t think Tony did it to drive sales to his affiliation partner. In the Fuji community, there is a good number of X shooters, who recommend to buy X-T3 over X-T4, unless you really want IBIS and longer battery life. Tony is just one of those.]
• in the X-T4 manual, it’s written that it has 20 minutes 4K60p limit, which can be shorter in hot outside temperatures
• he brought out his camera at 30˚ Celsius (86˚Fahrenheit) and shot at 4K60p
• after 20 minutes the camera asks to be turned off
• if you turn off at that point, and quickly switch on again, then you can record for 2 to 5 minutes again
• he turned the camera off and let it rest for 30 minutes on his balcony (at 86 fahrenheit)
• he then filmed for 19:30 again, before the camera turned off
• another 30 minutes break on the balcony
• he then filmed again 20 more minutes in 4K60p
• he gets the same results at H265 and H264
• no footage was lost. The camera always stored the file before shutting off
• the camera is not flawed like Tony Northrup says. It’s just not designed to film hours and hours of content in 4K60p. It’s written also in the manual that it has a 20 minutes limit in 4K60p
• 4K60p is the most intensive for the processor
• if he shoots at 4K30p, the manual says you can film 30 minutes (an arbitrary limit due to old EU tariffs). So it’s a software limit, not hardware limit
• he filmed 30 minutes 4K30p, got not overheating warning
• after 30 minutes, he just switched OFF and then immediately ON the camera again, and he filmed 30 more minutes, without any overheating warning
• he switched OFF and ON again, and it filmed again 30 minutes with no warning
• at 4K30p 30 minutes limit is purely software limit
• usually he never shoots 4K60p for a long time, he just needs it to make some slow motion B-Roll
• if you do not buy the Fujifilm X-T4 because of Tony Northrup, you will be missing out on an amazing hybrid camera

Now, I never run an torture test on my X-T4, but in all the long videos I filmed for my COVID-19 caused online lessons, my Fujifilm X-T4 was an extremely reliable film-partner.

The only thing that annoyed me, was that with my 64GB SD-Card, it recorded the video in 1 single clip, but when I switched to my 32GB card, it spilt the video in multiple smaller files. This is something that is written in the manual, and I forgot for a moment. So, from there on, I only used 64GB cards or higher, so I get one nice big file to work on in post.

I agree with Balbo42, the Fujifilm X-T4 is an amazing hybrid camera. Calling if flawed is… well… let’s say a “bold” statement.

But hey, this is FujiRumors. We share it all, and you guys make up your own mind.
