No surprise - sensor made by Sony

ChipMod provided a picture of the back of the sensor where we can clearly see IMX309AQJ and 1183456.

Audio part

As the D800 and the D4s, which I had measured before, the D850 mercilessly cuts off everything below 120Hz (-3dB cutoff frequency of a 2nd order highpass). To be totally clear, this is the "wide" setting. The only chance for a proper frequency response is to compensate in post, which is not straightforward with most audio editors. You cannot boost low frequencies before feeding the signal into the camera, as this would seriously over-drive the analog electronics. 19dB attenuation at 30Hz means that 9 times the voltage of a 1kHz signal is needed to get the same digital amplitude.

I have slight doubts in this measurements.

The second problem: clipping in the analog domain, before the signal is digitized, and well below digital full scale. The full digital range is never used, except in sensitivity settings 19 and 20, attenuator on. For a 1kHz sine signal, the maximum amplitude is about 3dB down from, or 71% of digital full scale in most settings, which corresponds to the top two bars (the red one plus one more) of the level indicator not lighting up. But with two bars dark, a 30Hz signal can already be clipped heavily, depending on sensitivity and attenuator settings. Due to that frequency dependence of the analog clipping limit as introduced by the aforementioned, analog high pass, it is not possible to use the level indicator to reliably prevent distortions.

Analog clipping in preamp?
Very hard to understand that all this means exactly.

PV will start to do some pro level audio measurements quite soon, btw with clear scientific explanations.

New firmware 1.11.

The update fixes the phenomenon that firmware for some lenses and accessories cannot be upgraded.

Nikon D850 is market as discontinued at B&H and few other stores.

Officially Nikon did not announce if they will keep producing it or they only have some old stock left.
