Uncompressed Raw coming to the Sony Mk2s

well the reaction sure was fast, who knew big cold corporation like Sony could be this agile :)

We have been crying about the RAWS since 2010. Somebody got a public petition going in the last year I think.

I think more agile would have been to give a proper RAW option in the beginning. :)

If the older cameras are not addressed, I give them little credit past self-interest.

I didn't see the A7II being mentioned but hope that was a mistake.

The upgrade is coming first to the A7rii, but then to "other E-mount cameras". IMO the A7ii is almost certainly on the list. I hope it'll also come to the A7 and A7r, which surely isn't too much to ask.

Not that I've ever found anything wrong with the compression, but it can be nice to have the uncompressed option.

i wonder if it'll actually make a difference!

If you overcook your raws (and use Adobe), then it will:



But you have to push *really* hard to see this in practise, and then pixel peep some. More interesting might be to see if the posterisation that Ming Thein reported (due to the compression's tone-curve) is resolved.

Bet most people are shooting jpeg though ;-)
 
Maybe users have something to do with that. If everyone ranted for the "lack of losslessly compressed raw", Sony might have done that. Instead, people cried for "uncomrpessed raw" and, lo & behold, that's what they get. Besides, some people have trouble with the concept ot raw and lossless compression, what with "raw should be pure untouched sensor data" and similar nonsense.

People have been speculating that the reason we're not getting lossless compression is because the processors were specifically designed to accommodate lossy compression.

It is far more likely that they felt that they could not research (and potentially avoid) patents applying to lossless RAW compression in time.

No patents involved with the lossless scheme used in DNG, for example. :)
 
Sony uses what amounts to a bespoke processor, right? It's specifically designed to process images. I don't think it's unreasonable to assume that the lossy raw compression is a hardware-based job, just like how h.265 compression/decompression is generally designed to be performed as a hardware-based job, not a software one, especially in the mobile sphere. It might be impossible for the current Bionz processor to losslessly compress raw files without draining too much battery-life, overheating the processor/camera, or simply taking too much time. Who's to say that the requirements would be so different for lossy vs lossless compression? I'm not sure, but it's not a bridge too far to imagine that this is the case.
