In other bad news for Canon, the a7R II's 399-point on-sensor phase-detection AF system is even capable of focusing Canon EF lenses very quickly and (so far as we can tell) very accurately. We experienced this combination at work in a very poorly lit conference room, and even so, focus with a Canon EF 24-70mm F4L was at least as fast as we'd expect from a native Canon body. Impressive stuff - especially if this performance is maintained for AF tracking out in the real world.

42.4MP... ignoring medium format, who would've thought that we'd have to call that not class-leading? You can thank the Canon 5DS and 5DS R for that, which the a7R II falls short of with respect to resolution. And yet, in almost every other respect, the sensor in the a7R II is bound to outclass the 50.6MP sensors in Canon's latest high-resolution beasts. Why? Read on...

Speaking of tracking, the high-speed readout of the image sensor also means fast and accurate tracking of your subject no matter where it moves to within the frame. In fact, the system can be so accurate as to find and track not just a face, but the eyes within a face. High speed readout means it can now do this continuously. And on-sensor phase-detect means the camera doesn't suffer from the inaccuracies dedicated phase-detect modules in DSLRs are prone to.

It looks like the hype surrounding the new Sony a7R II is justified… at least when it comes to sensor quality. DxOMark tested backside-illuminated full-frame sensor in the camera — a world’s first — and the sensor received the highest overall quality score ever awarded by the testing lab.

Wat bedoel je Amberes?
Raw is toch losless ?

DE: Oh, interesting. I would have though it would be, just... it would be faster, I didn't realize it would improve your noise levels as well.

This next question is more of a request maybe, but we've had a lot of questions asking about raw format. And...

KM: Ah, raw. <laughs> 14-bit.

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.

“The voice of our α community remains the most important guiding force of our product development plans,” said Neal Manowitz, Deputy Vice President for Digital Imaging at Sony Electronics. “The addition of Uncompressed 14-Bit RAW processing is a direct result of customer feedback. Widely requested by photo and video enthusiasts, we believe the choice of RAW processing types will further elevate the performance of these extraordinary cameras.”
