According to an interview with Kimio Maki, Sony Corp by imaging-resource, Sony currently is working on uncompressed RAW for mirrorless cameras, this feature will coming to a7RII one day by a firmware update. And Kimio Maki also told us some great features of the new announced Sony alpha a7RII (Amazon | B&H | Adorama).

From interview:

Uncompressed RAW

DE: Yeah, well 14-bit is OK, but many people are asking “could we please have uncompressed RAWs?”

KM: Sony RAW is compressed, not uncompressed. But if we’re getting a lot of requests for it, we should make such a kind of no-compression raw. Of course we recognize that. But I cannot give you a guarantee when we’re going to fix or not fix.

DE: Right. When you’re going to address that, yeah.

KM: Sure, sure. And so we recognize the customer’s requirement, and actually we are working on it.

DE: So it’s something that you’re aware of. I’m sure that the image processing pipeline is optimized for the way that it is now, but it seems to me that, while it might involve some trading off some performance, that it could just be a firmware change. Could it? Would you be able to provide uncompressed raw as a firmware update, or would it require new hardware?

KM: Right, yes. So… not hardware.

DE: It is firmware. OK, good! I think people would be willing to accept a slower transfer time or lower frame rate in an uncompressed mode. Some people really, really want that.


a7RII Noise Performance Better than a7R

DE: How does the noise level compare to that of the Sony A7R? You know, the A7R’s resolution is 36 megapixels, but it’s sensor technology is older, and so perhaps less advanced.

KM: It is better.

DE: The A7R Mark II has better noise performance; better than the A7R.

KM: Better than the other one. Because the copper layer is a big improvement over aluminum.

They also talked about why sensors is 42MP not 50MP, and Advantages of backside illuminated sensors and Hybrid Autofocus. You can read full interview at imaging-resource.
