After the D700, D7100, D5200 and D600, the Z7 is the latest Nikon camera to be reported to have banding issues – in spite of having an apparently identical sensor to the D850. It’s apparently due to the holes in the image produced by phase detection pixels – a problem I’ve mentioned several times before. The problem is that phase detection pixels do not precisely measure the quantity of light like regular sensels, so the electronics have to fake the data for those pixels.
Data obtained by DPReview, in part shown above, suggests the phenomenon starts to creep in by about a 4-stop push and becomes really noticeable at 6 stops. In all other respects, the sensor seems to behave like that of the D850.
Curious now to find out whether the Z6 is also affected.
