We also have to lok what happens to the IQ with over 49 mega pixels on one APS chip. Remember that every pixel is split in 2 for pdaf.

It might be safe to assume that IQ is going to be at least going to be equal to the prior 18mpx sensor (not a particularly high bar to be sure), as they are confident enough to boost native max ISO from 6400 to 12800, and expansion from 12800 to 25600.

NEX-5N/5R/6 - Exmor 16mpx, native max ISO = 25600, no expansion

NEX-7 - Exmor 24mpx, native max ISO = 16000, no expansion

D7100 - Toshiba 24mpx, native max ISO = 6400, expansion to 25600

D600 - Exmor(?) 24mpx, native max ISO = 6400, expansion to 25600

D800 - Exmor 36mpx, native max ISO = 6400, expansion to 25600

6D - 20mpx, native max ISO = 25600, expansion to 102400

5dMKIII - 22mpx, native max ISO = 25600, expansion to 102400

I have the 5N and 6D, and by my own unscientific seat-of-the-pants assessment, I will confidently use the 5N up to ISO1600 and accept ISO3200, while I will confidently use the 6D up to ISO6400 and accept ISO12800. The 6D is a high ISO monster.

(I tend to buy high ISO monsters because I prefer to scurry around in the dark.)
