Interesting patent application by Fujifilm: active sensor cooling for cameras with IBIS (In Body Image Stabilisation).
Fujifilm patent application 2022-55674 (Japan) discusses methods and technology to actively cool down an imaging sensor with IBIS.
PROBLEM TO BE SOLVED: To provide an imaging device and an imaging method including an imaging unit.
Conventionally, in an image pickup apparatus provided with a camera shake correction mechanism, a technique for cooling an image pickup element has been proposed.
In recent years, an image pickup device may be used to shoot a high-quality moving image for a long time. The image pickup device is preferably used in an appropriate temperature range. Shooting high-quality moving images consumes a lot of power, and the heat generated from the image pickup device itself exceeds the appropriate temperature range. In high-quality video shooting for a long time, the image pickup device activates a protection function such as forcibly terminating the shooting when the temperature exceeds an appropriate temperature range for the protection of the device itself and the safety of the photographer. Therefore, it may not be possible to secure a sufficient shooting time when shooting a high-quality moving image. Further, in the case of repeated shooting, if there is no time interval in which the temperature of the image pickup device, which has risen during the previous use, falls to an appropriate range, it is not possible to secure a sufficient shooting time. Further, in an image pickup device with a camera shake correction function, since the heat-generating image pickup element is always floating at the time of shooting, it is structurally difficult to dissipate the heat generated from the image pickup element.
The image pickup unit 100 includes three heat pipes 180A to 180C. The heat pipes 180A to 180C are heat transporters that transport heat. The ends of the heat pipes 180A to 180C are installed on the sheet metal 108C of the cooling device 108. Further, the other end of the heat pipes 180A to 180C is installed in the heat sink 110. As a result, the heat generated by the cooling device 108 is transported by the heat pipes 180A to 180C, and can be cooled by the forced cooling mechanism 46 at the transportation destination.
As described above, the heat generated from the cooling device 108 can be transported by using the heat pipes 180A to 180C, and the cooling can be performed by the forced cooling mechanism 46 at the transportation destination. As a result, it is not always necessary to equip the sheet metal 108C of the cooling device 108 with the forced cooling device, and the space inside the image pickup device main body 2 of the image pickup device 10 can be effectively used.
Here is an unfair comparison, the medium format Fujifilm GFX100S vs the full frame Canon EOS R6.

Alex Barrera wonders if medium format is worth it, and compares the Fujifilm GFX100S with the Canon EOS R6. It’s a short video so I won’t spoil it, but the answer is “not really” :-)
Hackers hit Canon last year, now it’s Fujifilm that has been hacked. Again it’s a ransomware attack.
Fuji Rumors reports that Fujifilm disclosed a ransomware attack on their network and that there has been an unauthorized access to their servers. Apparently their servers have been infected by the Qbot trojan malware.
Notification of communication failure to customers
2021 12:00 Update June 2, 2021 20:00
FUJIFILM Corporation is currently carrying out an investigation into possible unauthorized access to its server from outside of the company. As part of this investigation, the network is partially shut down and disconnected from external correspondence.
We want to state what we understand as of now and the measures that the company has taken. In the late evening of June 1, 2021, we became aware of the possibility of a ransomware attack. As a result, we have taken measures to suspend all affected systems in coordination with our various global entities.
We are currently working to determine the extent and the scale of the issue. We sincerely apologize to our customers and business partners for the inconvenience this has caused.
Latest BCN rankings on Japanese market shares on mirrorless camera sales shows that Fujifilm is on a steep rise.
BCN collects data of about 40% of the Japanese electronics and online stores. Their latest analysis shows a promising start into 2021 for Fujifilm. They are now very close to Canon’s second rank. Sony is also on the raise, and the undisputed market leader for mirrorless cameras in Japan. OM Digital (former Olympus), on the other hand, is on a downwards trend.
Two new cameras have been announced in the last days, the full frame Sony Alpha a1 and the medium format Fuifilm GFX 100S. Time to compare them with Canon’s EOS R5.
Over at B&H Photo you can use a rather useful camera comparison tool. We tried to compare the Sony Alpha a1 with the Fujifilm GFX 100S with the Canon EOS R5.
