Sony Formally Announces 100MP IMX461 With Support For 4k, 8k and 6fps


In March FujiAddict spotted the IMX461 sensor, which will be the next sensor used in the Fujifilm GFX. This BSI sensor is quite impressive and is capable of 6fps as well as 4k 30p and 8k 18p at 12bit. The new IMX461 sensor basically doubles the current Fujifilm GFX 50S’ capabilities in every way, but it’s unlikely that the 8k feature will be very useful, beyond maybe a high-speed shooting mode.

High speed shooting around 20fps has been big lately and a full sensor 8k read out at 18fps and 12 bit could be very useful if future GFX cameras are designed for faster moving subjects. Fujifilm has positioned themselves well to squeeze full frame out of existence if they can improve the performance of the GFX at a rate similar to their X system cameras.

It’s highly likely we will see a new Fujifilm GFX camera in 2019 or 2020 since this sensor is going to be released in 2018. The future Fujifilm GFX 100S will certainly be a desirable camera with a nice lens selection by the time we see it release. Maybe we will ever see the rumored range finder variant (GFX R) or fixed lens camera by then too. If you think GFX files look great today wait until the next GFX is released.

    “Fujifilm has positioned themselves well to squeeze full frame out of existence…”

    It will take processing power and throughput technology well beyond what we have now to do that. I would estimate the generation after next, probably.

    • Actually there is probably enough processing power today… this sensor won’t reach the gfx for 2 more years. You would be surprised at the amount of processing power available today, but that’s a bit beyond discussing photography. Parallel processing is a useful tool and modern bus speeds increased dramatically this year. The GFX 50S didn’t get to benifit from these advances at all and the next GFX will be designed with these in mind around 2019.

        “Parallel processing is a useful tool and modern bus speeds increased dramatically this year.”

        Sure. But packing that into the relatively small space of a camera and engineering proper heat dissipation (heat which contributes to sensor noise) is the challenge.

        • The sensor getting hot… not the processors… cameras have one or two processors today. Some cell phones have 2-3 processors and they are multi core… the GFX was designed with a processor that was already 2-3 years old when they thought of creating the camera… they slightly modified the xpro2 processor. Fujifilm isn’t even getting close to the max processor efficiency out there. Sony ties the line, but even they will recycle the a9 processors for a while to come. Processing isn’t your issue.

          Profit margins are king here. The gfx is a cash cow for Fujifilm and they can choose to continue that or to make more in the long term. There are tons of factors that will come into play when designing the next gfx and it’s likely all of the parts are final today… it really depends how they work with suppliers.

            Yes, sensors generate heat. So do processors. The two combined present signal issues. It was — and remains — one of the chief issues in the design of Sony’s A9 stacked sensor (which affixes the processing to the backside of the sensor).
