image courtesy of MeshmagMesh Mag might have figured out how Sony is producing medium format sensors affordably for cameras like the Fujifilm GFX 50S and Hasselblad X1D. It looks like Sony is merging 4 smaller sensors together to make one large sensor. I wonder what the limitations of this technology are because we could see some affordable huge sensors in the near future.
This could also explain some of the properties of this class of medium format sensors, like how sensor readout speed is prioritized and limited at times. It could also be what prevents the sensor from outputting a 4k video. I wonder if we will ever find out what four sensors were merged to make the excellent GFX sensor (They are just about m43 sized). You can read Mesh Mag’s translated write up here. I will try to reproduce their results in the near future and report my findings.
I ran the test myself and it seems my sensor doesn’t really show the 4 parts of the sensor until running the test for 16 minutes. The 8 minute test is barely visible even at 100% and if you use long exposure noise reduction the frame becomes very clean with +5EV and +100 White in Lightroom. All of these images are flat black when first imported. It appears that the biggest advantage of using long exposure noise reduction comes from when you need to adjust exposure after the fact.
I want to apologize for placing so many FujiAddict watermarks on the image, but a site that doesn’t have a GFX has been copying my posts. It seems not all GFX sensors are created equally. I am curious if there are any cameras out there that can go longer than 16 minutes without showing the parts of the sensor.
Interview with Dan Bracaglia from DPReview about the GFX. Apparently their review will be done sometime next week.
