A7rII : What is the bit rate of uncompressed RAW on silent shooting?

Rhawi Dantas

This is only for those who have updated it: Will we get 14 or 12 bit when using silent shutter on latest firmware?thanks


Dr Tone

12 bit, nothing has changed in that regard.

TommieH

Is it 12 bit for all continous modes as well?


Lightshow

I don't know why they don't just give us lossless compressed 14bit across the board, Canon's been doing it for a while now.

But maybe the reason is hardware related instead of software, so that is why I was looking for someone that actually understands the innards to give a shout. Silent shooting is one of the best features of this camera with only 2 downsides: rolling shutter (which either Sony comes up with a leaf lens or global shutter) and the 12 bit depth. They could eliminate one of them at least.

So no one that can answer if the 12-bit mode is still active even if choosing uncompressed RAW when shooting in continous modes? I've searched all the internet but no one seems to adress that at all. This is especially important when using stuff such as continous bracketing.

If you anticipate having to push the shadows more than 3 stops or so, it matters.But that's not something that you do all the time.A lot of the time the silent shutter, or the continuous mode, is very useful and the 12 bit mode will cause no visible bad - even at 100%. Just bear in mind your limits of pushing.

Even if not pushing hard the difference in tonality and noise is obvious.It's quite idiotic that the continous modes such as bracketing still uses 12-bit even if one chooses uncompressed RAW since bracketing is one of those functions one use to maximize DR; to then loose a stop of DR ...

My claim is just that when you don't need it it doesn't matter. And that you don't need it that often.And if you always lost that stop of dynamic range, imagine the forum rage -- not to mention the fact that it would look bad at DXO.By claim is not that it's "hardly noticeable". It's that there are situations where it's noticeable, where very significant shadow pulls are involved. But most situations where its *not noticeable at all*Consider Canon sensors. It's not that they produce routinely sh*t pictures. In most cases they are *every bit as visually good looking, resolution for resolution* as our Sony ones. It's just that, having dynamic range possible even a bit less good than 12 bit mode on Sony, there are situations where the shadows, wen pushed will be very noisy.The take home message is that with many features of sensors, they are not "overall" features that show up across images. They are features which show up in particular contexts, and otherwise can't be seen. Same is true of the compression artefacts on Sony. When people say they are mild they don't mean that they are everywhere but not very important. They mean that mostly they aren't there at all, except is particular circumstances.

Only in certain modes as silent shutter, continous modes etc.I still don't agree that it is only noticable when one pushes shadows too hard. A gentle push will do just fine to show lesser tonality. Something that seems to actually improve with the uncompressed option (awaiting reports for that as well but unfortunately only a few handful of people do the really technical reviews). So not only one looses a stop of DR but the tonality is affected as well by the drop to 12-bit.As someone that only shoot landscapes/urban that isn't exactly great.Don't get the Canon reference. Ofcourse one can produce amazing images with less DR. There isn't a debate going on about that.And c'mon -- you must see that Silent Shooting Mode basically is "Church Mode". Who here has been to a church and have not thought about DR?And who would freely drop to a 12-bit mode in that case if that was an option just because "it doesn't matter that much" ?
