On Sony Alpha 7R II: Real-world ISO invariance study article (334 comments in total)
In reply to:

igor_s: Jiom Kasson showed that the A7RII ISO-invariance holds in the range 640-12K ISO, and it breaks at lower ISOs.
Here we see that the images below ISO 800 get progressively noisier which is in agreement with above.

Yes I agreed it is far too much push of exposure.

It is clear that ISO 100 is not sufficient enough light for low light shooting. ISO 800 or more is much better result I tried when I download your raw file. The ISO 100 the shadow is clipped so badly it is impossible to recover nicely and end up with rear end ugly artifacts. So I tried the ISO 800 and had no problem recover the shadow with ease and no artifacts were observed. I did not need exposure push at all, it looks good. It demonstrates that ISO 100 is useless anyway for low light, I prefer higher ISO as a result for better recoverable of shadow in particular and less noise in shadow with lower recovery amount so it looks much cleaner. That's for low light photography. Interesting post though. Thanks for showing that. I think it is totally unnecessary to have 14 bit raw file usually if I were to use higher ISO for low light especially starting from 800, that's more than satisfied enough.

Rick Knepper: Would you mind sharing your optimal ACR settings? I downloaded the ISO 100 file and no matter what I did, the image was riddled with noise by +2 when looking at it 3840x2160. I can't post an image here, but did you realize there was a bum laid out in the store's entryway?

I'm with Rick, same story on 4K screen so easily can see how noisy it is. Not sure whats up with this?

Wow that's interesting invariance, rather significant to me! I am so glad you are exposing it to show to Sony that is not good enough. So disappointed to see this. Its safe to say using ISO 800 or better are better option for low light with less artefact. I could try that with my A7 to see how it behaves to compare to this newer A7RII. It seems the image process behaves so differently at ISO 800 for low light shooting. Thanks DPR for showing us great example. What you said is true igor_s. Sony needs to step up the game and give us 14 bit raw option if they wanna stay in competition. That's what we want!

I really like that sample, doing so good job from JPEG. I have no problem with new format. Dislike RAW but probably Lightroom hasn't yet incorporate the latest Colour Profile for that camera.

Lassoni: I'm sorry to say this, but the results look terribly bad. Only the first image looked interesting, but the rest are terrible.

Yeah I am not convince either Lassoni but at later version might be improved. Time will tell.

If it were rugged it would make it harder to tear device apart. (Real weather sealed)

Yup that's why that picture tells me a lot more than that, not rugged enough to me.

I would be happy to see Sony has not won award. Karma bit them back cos of artefact problem in raw compressed files and shadow noise/speckles problem in recent new A7RII and heating issue problem also! That's why I am staying with A7 until Sony better hurry up and move their lazy hairy fairy ass and fix it! And offer uncompressed raw!

ShutterNot: Paparazzi are totally uncivilized and rude, and the people that pay for the pictures they take are a bunch of greedy folks that will do anything for money.
It's one thing to take pictures when famous folks are out in public, it's another altogether when you start stalking someone. What is to distinguish that type a photographer from a common pedophile, a thief, or a murderer ? They flash a badge that says .... hey it's OK I stalk you, I'm only taking pictures ?

Don't feed the troll. Enough said.

Yup sadly what you said is very true. I never forget what happened to poor Diana.

www_zeeshan_de: The best ISP is a chip not touching the RAW data and giving the RAW data as output. No need for stupid interpolation algorithms from ISPs. With RAW, every body has the freedom to build the final image on their own, with or without interpolation.

Nobody care about RAW in mobile phone, its taking up too much space. JPEG is the way to go. RAW can stay in proper DSLR format.

Tape5: This camera is a top sensor and a lens lover. But best of all it is more throw-away than anything the competition can make.
Very soon, Sony will produce cameras that would be first choices for any lens collection and in many ways we are there already.

Just try not to overlook the issue problem with RAW compression ARW 2.3 is still there for artefact things in high contrast area like white against black for example. I just hoping for best they are still working on it to offer lossless non compressed RAW option. They are awesome image but it just one little thing if Sony can give us something as a favour in return for we buy from them. We want to be able to use shadow push/pull without any artefact. Sadly someone have post artefact being observed with a bit of push/pull, no where extreme push/pull when retrieved from Photography Blog.

That camera still very impressive otherwise though!

In reply to:

HowaboutRAW: naththo,

What is the meaning of +7.

The two jpegs together as the same image, all the tells me is that ACR desaturates the files--and that's not what I'm refering to.

As I said already the example you posted isn't the greatest for this point, but it doesn't look like strong colour to me anyway.

11 bit plus 7 delta bit in current V 2.3 ARW format.

In reply to:

HowaboutRAW: photomad:

Um, what's so great about the A7 except that it's smaller than this Canon?

It has washed out colour in raw, and a very very audible mechanical shutter. And with its 24MPs, it has about the high ISO performance of this 50MP Canon. It's good for video though.

And I like using EVFs in lowlight shooting, but the A7S is better for that than the A7.

Oh ok I should have explain more. My apologised. The only thing I liked about is the colour in Sony though out of RAW which I was looking for. I do not like to see lack of colour/mute that I am not really fan of. It is important to ensure everything are looking good straight out of RAW with minimum adjustment is the best thing to get. I think that A7RII is much better than A7 for that so far which is impressed because it helps a lot by BSI-CMOS due to direct hit the sensor rather than having to go through to the end on old conventional CMOS that can causes issue problem.

In reply to:

piratejabez: Overall IQ is fantastic! Skin tones however seem very flat and muted (with some peculiar blues as well)—typical "Adobe Standard" color profile? Are there any Sony color profiles available yet for ACR?
Perhaps you could add a real-world RAW+JPEG image so we can compare OOC jpeg and ACR default color rendition?

Yeah I would not trust Adobe Standard colour, since it is not realistic to me. Yeah I agreed adding JPEG next to that would be useful to compare.
