p.1 #1 · p.1 #1 · DR on a7iii/a7riii


Anyone have any educated guesses/theories on the DR of the next gen. of Sony FF cameras? Think we get an ISO 64, or can hit 15 stops of DR at base ISO?

DR maybe somewhere closed to D810 @ low iso and about 1/3->1/2 stops better than A7R2/A9 @ hi iso assumed A7(r)iii has EXMOR R(S) sensor with the deeper wells (Gen4) retrofitted this time: https://www.framos.com/en/news/what-is-sony-s-exmor-technology-anyway

I'm going to go with: Not much different. Whatever Nikon does with the D850 is probably around the ceiling at base ISO. If we get more resolution, we might even backslide a tiny bit on DR at full resolution-- but I sure hope not. I'd still favor DR over resolution, even at the current specs of the A7rII.

I'm a proponent of more DR and more resolution, if we can get them without going backwards elsewhere at normalized output. But, more often I see places where increased DR would be beneficial to me than increased resolution.

I wouldn't put much stock in my prediction, or that of anyone else. After all, neither camera is even a rumor at this point-- and nobody in the public even knows if cameras will those names will ever be announced (although we sure hope so).

A7R II with big battery and faster AF and no sensor change would be good enough for me.

A7Rii is plenty for me but I want more DR plus resolution to retire my A7R. I will be happy if the A7(R)iii is cleaner than A7R at low iso range and cleaner than A7Rii at hi-iso range. Imo, wider ISO range PDR will be better with the deeper wells mods on any BSI (stack/non-stack) structure sensor

Would love to see pixel shift option available for A7(R) iii for higher DR and resolution
