Let’s digg into the possible Sony 36MP sensor specs and performance!

I am sure the A9II will be announced in October but I am yet not 100% sure which sensor it will use. There is a fair chance the A9II will use this IMX435 36MP sensor registered end of 2018. So let’s digg into the specs:

• 36MP sensor
• 10fps  at 16 Bit. But frame rate goes up at 14bits!
• It has 6 native sensitivities (from base to top as seen in the table):
  ISO50 = Conversion Gain -18dB, EI +12dB, DR 17.4EV
  ISO200 = Conversion Gain 0dB, EI +6dB, DR 15.4EV
  ISO800 = Conversion Gain +18dB, EI 0dB, DR 13.4EV
  ISO12800 = Conversion Gain +36dB, EI +6dB
  ISO102400 = Conversion Gain +54dB, EI +6dB
  ISO1638.4K = Conversion Gain +72dB, EI +24dB
• IMX435 STARVIS use Hecx Native Conversion Gain to Produce more SNR in Dark Scene: (ISO 15 ~ 17.5EV/ISO 100 ~ 15.4EV/…/ISO 409600 ~ 6.9EV)
• If readout all Conversion Gain, the Landscape can be extended to 120dB, like the high SNR sensor sony displayed on IEDM 2018. But IMX435 seems impossible to do this. It’s not a still picture style sensor.
• Its full well capacity at base is particularly impressive at 605k e-, A7SII sensor IMX235 is “only” 159K e- with much bigger photosite. This again highlights the power of Exmor RS.”
