The Nikon D850 contains one of the most highly regarded sensors on the market today, and Nikon has touted the fact that it was designed entirely by Nikon and not simply an off-the-shelf sensor. But in case you were wondering who its manufactured by, a new report has now concluded that it’s a Sony-made sensor.
ChipMod over at astrocn.org disassembled a Nikon D850 and removed the 46-megapixel CMOS sensor from the metal frame, exposing the hidden model name on the back. “IMX309AQJ” is clearly visible.

According to Nikon Rumors “All Sony CMOS sensors have model names that start with IMX. A quick online search also confirmed that the sensor is a Sony IMX309AQJ”.
ChipMod also says that the characteristics of the sensor are typical of Sony-made sensors, but that the sensor is clearly different from the sensors found in Sony’s a7 II and a7 III mirrorless cameras.
This seems to confirm the fact that Nikon designed the D850’s sensor and had Sony manufacture it to Nikon’s specifications.
The Nikon D850 received a score of 100 over at DxOMark, the highest mark ever achieved by a full-frame DSLR (and tied with the mirrorless Sony a7R III). If ChipMod’s analysis is correct, then Sony-manufactured sensors are the two highest quality sensors ever made for 35mm full frame cameras.
Sony’s dominance continues all the way up, too: the medium format Hasselblad X1D and Pentax 645Z reportedly use Sony-manufactured sensors as well.
Sony reportedly keeps its best sensor designs for its own cameras, but it appears that a Nikon-designed (Sony-manufactured) sensor has now matched the quality of Sony’s best.
