Sony 100MP (crop) and 150MP sensors in 2018
« on: November 11, 2017, 11:41:23 am »

Hi,

Both this sensors to be released in 2018 were first introduced in some shows, but today Sony added the info to their webpage: https://www.sony-semicon.co.jp/products_en/IS/sensor2/application/index.html . This is probably what we will see in future Hasselblad, Fuji, Phase One or Pentax future products... all sensors are BSI, and the 100MP can do 6fps and the 150MP 5fps, by the way, they record 4k video.

Thanks, great link. Two things:
Why need a 16bit AD converter for 14bit files?
The 100 mp FI 54X40 sensor could very well be a "bargain" sensor. For Pentax 645Z?
Best

Why need a 16bit AD converter for 14bit files?

The current 100mp sensor has more than 14 bits of  usable information, requiring a 16 bit a/d.  Sounds like the new one is similar?  (I didn't read the specs, just noting that sony already is producing a sensor that requires a 16bit a/d to maximum the information).

Hi,

Phase One actually introduced a new 16 bit format for the IQ3100MP. The older format was actually 14-bit, blown up to 16 bits in raw conversion.

It is interesting that Sony says 2FPS at 14 bits for the 100 MP sensor. My understanding is that Sony uses ramp type ADCs that measure the clocks to charge (or discharge) a reference capacitor until voltage match occurs. They can make that ramp less steep, increasing conversion time but gaining more precision.

It seems that the IQ3100MP pixels have a DR around 15 bits. To make full use of that, 15 bit conversion would be needed, taking twice the time compared to 14-bits. That would yield around 1 FPS maximum. What is the FPS on the FX?

The DR depends on full well capacity and readout noise, mainly. The small pixels of the 100MP sensors probably means lower full well capacity, but it is quite possible that Sony has reduced readout noise so more than 14 bits are needed.

The 150MP sensor is capable of 4 FPS at 14 bits and the 100 MP sensor is capable of 6 FPS at 14 bits.

I am not sure that 6 FPS makes a lot of sense with DSLRs, but it can probably be useful on mirrorless.

Best regards
Erik
