All Sony Alpha Camera Have A Noise Bug

[Yomo]

On my A7s I noticed that when shooting in SLOG2 if I go up to ISO 8000 the image will have a different noise pattern than if I go up to ISO 10,000 and then down to ISO 8000, same ISO but totally different noise

I know that people have reported a similar issue with the A7sii with SLOG3 but what I read was it was believed to only be a bug with that picture profile

 

It's this kind of "Trick" ISO that does something weird to the noise

Going up give the ISO a kind of "Dirty" grain but going down to the very same ISO will give the ISO a "Clean" grain

 

I compared Native 3200 to this ISO 8000 when it had a "Clean" noise and also the "Dirty" noise

The thing is I see this not just on SLOG2..I see it on all picture profiles..on multiple different camera models...

 

On the A7s this happens on the following Picture Profiles on the following ISOs:

Here is a video of me going over the issue and explaining more in-depth:

I shoot stills but thanks for the heads up. My typical

shooting conditions would hugely benefit of an a7S,

but my budget calls for my a7-II. Shooting in near

darkness is normal to me, so I accept that there will  

be noise, and instead of [pointlessly] trying to avoid

noise I become a connoisseur of noise, seeking the 

more "photographic" looking versions, ducking the

more grotesque versions. So I will definitely check

out whether I can use this bug to my advantage !
