Industry News: Fujifilm Files Patent For Active Sensor Cooling System For Cameras With IBIS

Fujifilm

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.

Fujifilm GFX100S vs Canon R6: Medium Format Worth It? (not really)

Fujifilm Gfx100s

Here is an unfair comparison, the medium format Fujifilm GFX100S vs the full frame Canon EOS R6.

Fujifilm GFX100S at a glance:

  • 102MP Medium Format BSI CMOS Sensor
  • X-Processor 4 Image Processor
  • 4K30 Video; F-Log Gamma, 12-Bit Raw Out
  • 3.69m-Dot OLED EVF
  • 3.2″ 2.36m-Dot Tilting Touchscreen LCD
  • 5-Axis Sensor-Shift Image Stabilization
  • 425-Point Phase-Detection Autofocus
  • ISO 100-12800, up to 5 fps Shooting
  • 400MP Pixel Shift Multi-Shot
  • 19 Film Simulation Modes

Canon EOS R6 at a glance:

  • 20MP Full-Frame CMOS Sensor
  • DIGIC X Image Processor
  • 4K60p and FHD 120p 10-Bit Internal Video
  • Sensor-Shift 5-Axis Image Stabilization
  • 12 fps Mech. Shutter, 20 fps E. Shutter
  • Dual Pixel CMOS AF II with 1053 Points
  • 0.5″ 3.69m-Dot OLED EVF
  • 3″ 1.62m-Dot Vari-Angle Touchscreen LCD
  • Subject Tracking with Deep Learning
  • Dual SD UHS-II Memory Card Slots

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” :-)

Industry News: Fujifilm Suffers Cyber-attack, Shuts Down Servers

Fujifilm

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.

Fujifilm’s statement:

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.

BCN Rankings: Fujifilm On The Rise, Gets Close To Canon, Sony Still First

Bcn Rankings

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.

Sony Alpha a1 vs Canon EOS R5 vs Fujifilm GFX 100S Specification Comparison

Sony Alpha A1

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.

From left to right: Sony Alpha a1 with the Fujifilm GFX 100S with the Canon EOS R5:

Which One Is The Best Entry-Level Mirrorless Camera? (Canon EOS M50 vs Fuji X-T200 vs Sony a6100)

Best Entry-level Mirrorless Camera

The best entry-level mirrorless camera. Hot question, isn’t it?

DPReview‘s Chris and Jordan compare the Fujifilm X-T200, the Sony a6100 and the Canon EOS M50. And the question is: which one is right for you? While we are (obviously) rooting for the EOS M50, the Fujifilm X-T200 might…well…be interesting too.
