a7RIV pixel pitch and EDR
4

The pixel pitch of the newly announced camera turns out to be 3.76 um, the same as the IMX 461 Sony 100 MP 33x44 mm sensor and the same as the IMX 411 150 MP Sony sensor used in the IQ4-150.

A coincidence? Probably not.

15 stops EDR implies RN of FWC/32000. IQ4-150 has about 3 e- of RN at base ISO, but FWC is less than the 100,000 e- you'd need for that. So, maybe Sony has figured out a way to lower base-ISO RN or increase FWC in a completely new pixel design, and they decided to go with a pitch they'd used before, or maybe the 15 stops means something else to them.
