Whether intentional or unintentional - Sony has published even more specs than the visible page reveals with a placeholder for a teaser video of the upcoming Alpha 7 IV in the landing page tags.
Sony Alpha Rumors immediately collected and published them.
So it&s now clear that the A7 III successor will inherit some key film specs from the A7 III S. Among others, 10-bit 4:2:2 HLG video recording, an all-I XAVC S-I codec as well as Slog 3.
The 33MP specification clearly speaks for a sensor that will come up with more than 6K native resolution. For 8K, however, the typical 3:2 aspect ratio would have to be abandoned, which seems very unlikely for a hybrid DSLM. Still, 33MP is considered typical for 16:9 8K sensors in particular.
According to tags, the camera will be able to record 4K at up to 60p, though an earlier rumor rumored that cleanest downsampling will only be possible with 4K up to 30p.
Also of note are the 15+ stops of dynamic range mentioned, officially putting it on par with the Sony Alpha 7S III.
That would surprise us less, because even with the release of the Sony Alpha 7 III, it was on par with the then-current behemoth model Alpha 7 II S.
Be that as it may, in a few days (on October 21) Sony wants to bring even more clarity to the matter. Thus, it can be considered certain that the new A7 camera will be released this year. Oh yes, the first price rumor is at least 2500 Euros.
