Internal photo of Fujifilm GFX 50S II medium format camera

Lately I’ve been doing some Fujifilm GFX camera gear repair and decided it’s good idea to show some of the internal photo. There are few other teardowns such as here by Kolari Vision or one from Lensrentals.com for high-end GFX 100 model. There is also teardown of smaller older first-generation GFX50S from Kolari Vision here. Some internal bits also revealed in news while ago.

But none of those publications have juicy high resolution detailed images of the camera guts, so let’s fix that here. But nobody yet showing newer GFX 50S II guts yet. I’ve been checking few items inside and took the high-resolution image of electronics, with LCD rear panel removed. Enjoy 95MP high resolution image of the GFX 50S II guts. These cameras are still pretty expensive on used market so not many of the broken ones are out there.

There are lot of components on HDI dense multi-layer PCB. In the center we got Fujifilm X-processor 4 with Micron PoP memory chip with marking D9XFN. According to handy Micron FBGA decoder page this memory device is Micron MT53E256M64D4NZ-053 WT:B. This is a 16 Gbit mobile LPDDR4 SDRAM device rated for 1866 MHz clock rate with 256M x 64 organization. This is 25% of the memory available on larger GFX 100 body. Today in 2024 this memory is already ghost of the past and obsolete.

We got plenty of FPC connectors on this board, with some going to the huge SONY IMX 4.3 series medium format 44×33mm sensor with 50 MP of resolution. One can find number of DC-DC controllers with markings:

Little PCB in the left top corner also hosts clock/RTC coin cell battery with 6.8mm diameter. If this battery goes dead camera would be forgetting current date/time settings when main battery is removed/discharged fully. I’ve also got some images of previous top-end GFX 100 published on windychi.com site if you like this kind of teardowns.

Stay tuned for more information in future on xDevs pages. If you are interested and want to discuss details, you are welcome at our own IRC chat server: xdevs.com (port 6010, channel: #xDevs.com) or by reaching out with email.
