alexzn: Computational photography is the point of using a phone camera. Raw quality will never match what a real camera can do because it had a much bigger lens and a much bigger sensor. But computational photography makes it all moot because the imaging pipeline is attached to a much more powerful computer than any photo camera has. So Sebastiaan is missing the point entirely. It is still surprising that Apple didn’t find a way to leverage better hardware to produce better photos.

Actually not so much about 'power', really it's about convenience. One can take their $5000 ILC setup and shoot raw, suck it into their PC, and do whatever computational magic one feels like. Of course one may have to take multiple exposures/bracket, etc to get the best benefits esp. in low light.

The point being, and I bring this up cuz many other posts seem to miss the point, the magic is generally about making it easier to get very good quality photos. Various keyboard jockeys will inevitably want to compare to dedicated cameras, but the fact that today's phones can take pretty impressive pictures with little knowledge on the users part is the point of the exercise, not that someone who actually knows 'what they're doing' can eek out better pictures on some dedicated rig.

JimmyPragmatic: If this had a 18+mp sensor. And an electronic shutter like the A9 this would be perfect and I'd replace all my camera's. I suspect this will happen. Maybe 2023? I'll wait :)

@strobist guess your theory explains why Tesla is constantly eschewing innovation to focus only on the bottom line, and why Amazon has gotten to where it is since they've obviously always put the shareholder first and why Sony decided to buck the trend and go mirrorless with an uber aggressive update schedule, shareholder bottom line.

The grossly oversimplified notion of 'fat companies only being beholden to shareholders' truly is outdated and is as wrong thinking as saying 'photographers' and pretending that there is some global generic single mindset that everyone who uses any sort of camera falls into.

El Jeffe: Been saying for a long time the future is Ai and Panasonic LUMIX is headed down that road.
Also be aware the lens has everything to do with it. Need a good motor / firmware (yes lenses are computers too) and a macro is not going to focus as fast as a wide angle.

@el jeffe, I think BluenoseNS's point is that your statement is obvious, even if we are at the infant stage. Also that Sony has talked extensively about the amount of effort they put into getting the E series lenses to be able to keep up with the likes of the A9 by focusing on (no pun intended) more efficient motors. Plus LIDAR could be use to help focus macro faster than current methods.

GrapeJam: The tone actually looks quite decent but man, Sony highlight roll off got better but is still really harsh and obnoxious.

@grapejam, I know that you're using 'previous observation' to formulate your comments, but given the two examples you provided, I'm just curious as to how to can ascribe what you see to fundamentals of the camera vs other conditions (the shooter, the lens, etc)? Would you happen to have examples of something a bit more controlled, e.g. side by side of different cameras taking the same shot where the Sony exhibits the behaviour you describe? Pref. RAW.

Bodkins Best Photography: I had the a6000 for all of a day before I sent it back. Nothing could have prepared me for how uncomfortable and miniature that thing was.

Def personal preference. I switched from a Nikon DSLR to the A6000 years ago and appreciated the reduction in size/weight (I'm 6'1" with decently large hands) and the form factor has never been an issue for me. When I pick up an A7RIV it feels huge to me.

DotCom Editor: The 2002 movie "Russuan Ark" actually WAS filmed in one continuous, 99-minute take. No fakery.

To be fair, "Russuan Ark" was filmed in a much more controlled environment with significantly simpler (not simple) logistics.

RecklessCoding: This is, in many ways, a better move than what most Western companies do, where they distribute AI R&D across divisions/labs out of fear of regulations, often resulting to overlap.

I actually met Prof Hiroaki Kitano, who described to me and others over dinner how Sony has been investing to AI R&D way before the current AI hype circle. He talked a lot about his passion on AI for healthcare and robotics. I never thought that Sony will take the next step to create a separate division to consolidate efforts within their vast organisation.

I am particularly happy about the inclusion of AI ethics even in the press announce. Not only as this is my current research domain (and what I discussed about in a panel with Kitano when I met him), but also as it signifies their importance to Sony AI.

Overall, this is an amazing announcement and not just for photographers! It needs to be said, Kitano is a visionary and for a long time was chair of IJCAI. I am very happy that he is leading this.

@marek, I don't understand what you're getting at. Are you saying that AI won't be used to try to solve large scale problems? If so, then you are the one being naive. It's being used to analyze data from the subatomic level to planetary level as well as doing mundane tasks such detecting cats in videos.

However, if you're saying that @athonline is being naive to think that AI won't be used to do a host of negative things, while I'd completely agree that there are many nefarious uses for AI, I don't think @athonline was implying that AI would only be used for 'good' or that even research done by himself/Kitano-san might not end up being used for bad purposes regardless of initial positive intent (e.g. cat seeking missiles).

sirhawkeye64: This article is going to open a large can of worms probably.... thanks for posting DPR.
I mean don't get me wrong, the camera is cool, but I'm sure people are going to get into arguments on DT and whether he should be impeached or not....

Why would they impeach Burnett for using a MF camera? I'd understand if he was using flash powder for the full retro effect though.

Clint Dunn: Man, so much whining. I don't shoot Fuji, I'm a Leica guy. That said I used to own the X-Pro1 and this new X-Pro3 looks to be a better camera in every way. Some people are never happy I guess...
Here's the thing, in an age where camera companies are threatened with extinction Fuji is trying to do something different. This is a good thing...

@clint, it's interesting how folks 'defending' the unique characteristics that makes a particular camera attractive to them will use words like 'boring' to put down other cameras. Any camera is as 'boring', 'exciting', 'sterile', 'inspirational' as the person behind the camera allows it to be.

Interesting, I found the 5 lux iphone photo to be far superiour to the pixel. The pixel's photo is overexposed and you lose a ton of detail and contrast and it just looks overall more washed out.

yakovlev: I don't know where the DPreview team is traveling, but when I travel a good half of my pictures are indoors without a tripod, where the Canons are going to be clearly superior. Same with family photos, where many of them are indoors and benefit from a bright lens.

I don't understand the love that DPreview is showering on the RX100 VII here. Whenever I suggest one of these large sensor compacts, it's all about being able to get good indoor shots that aren't overly grainy or with excessive motion blur. The older RX100 V was great for that, as are the current Canons described here, but the RX100 VI/VII dropped the bright lens in favor of reach.

Ultimately, the problem may be the categories not having clear meaning. If AF-C autofocus wins every category, then the categories are wrong. They need to be more like: Indoor Architecture (tie), Indoor Portrait (Canon), Indoor Action (both bad, Sony better), Landscape (Sony), Outdoor Portrait (Canon), Outdoor Action (Sony), Video (Sony)

@megafolie for traveling battery life can be a big deal. It's not so much the size as it is the annoyance of having to constantly change batteries in the middle of whatever you're doing, and, worst of all, having a reasonable way to charge them _all_ overnight. Assuming your camera does in camera charging, you still need to have an extra charger (unless you like waking up in the middle of the night to swap batteries). If you carry 3 or more batteries (not that uncommon), then the problem just gets worse. It's annoying for someone like me who wants to take a lot of pictures and am willing to live with some of the hassles, for someone like my wife who isn't as committed, it's the difference between using the camera or not.

mr.izo: please, elaborate this figures. original article mentions 6% of sale shortage, where then this 40% comes from, which division and period we're talking here, profits as a whole, mothly period, quartet, year etc etc? so much bs this days..

40% drop in profit on 6% drop in revenue projected for the year, 50% drop in profit on 10% drop in revenue likely to be reported for the 1H. At least that's how I read it.

Acts very much like a very high framerate frame differential algo (think global shutter with redundancy removal done upstream). I wonder if the receptor sites are polled or are truly async as the latter might make scaling to higher resolutions very difficult.

chida: Steve Jobs would have definitely made a more simple and better design than this one! This is looking too complex! For such a giant power packed machine, at least 1 TB SSD was absolute necessity!

If you can store your media on a 1TB SSD, this isn't the machine for you. Base drive is for the OS only, serious users will stack multiple TB of thunderbolt storage plus SAN.

Not impressed by the shot the photog ended up getting. Had he been using an A9 he could have gotten a shot of the ball in flight right before it pegged the camera ;)

thx1138: Says a lot about America's pathetic legal system this even had to go to appeal. The District of Vriginia ruling was a disgrace.

One could also argue that it says a lot about America's strong legal system that a misruling can be overturned as a matter of course. No system is perfect so a system that understands that and has provisions for dealing with it seems to be far from "pathetic".

DotCom Editor: The billions spent annually on data security are a waste of money. It has been shown numerous times that any system can be hacked into — government, retail, manufacturing, transportation, etc. Even security company RSA itself suffered a major breach several years ago.

I've long proposed that organizations cut spending on security to near zero and instead encrypt everything. Let the bad guys have all the data they want; just render it unuseable. But, you've got to encrypt absolutely everything.

This strategy was impractical years ago due to the processing overhead of encryption, decryption, and re-encryption as data is created, modified, and stored, That argument has largely dissipated with today's powerful processors and multi-gigabit transmission speeds. Industry analysts, CIOs, and security executives now agree that this approach has considerable merit, though none will say so publicly. No security exec will ever admit on the record that security is essentially useless.

I may be being pedantic but isn't encryption just one aspect of security? If a company decides to pay the expense of doing the software changes necessary to encrypt/decrypt at every process/host entry/exit point, aren't you spending money on "security"?

I would think that folks like actors are the one's that are in trouble. The studios themselves will simply pivot to take advantage of the tech.

SirPeepsalot: Are these claimed to be real-time achievable at reasonable fps on a commodity (even if high-end) hardware ? Because touting game engines with pre-rendered scenes that would otherwise run at 640x480@0.5fps is very 1998.

@peeps, long ago someone very wise said to dismiss a technology or competitor simply due to hardware limitations is a fatal decision. So what that it can't be done real time now, just like 4K video could not be decoded realtime by anything remotely resembling commodity in 1998 but is easily done by $200 tv's and $50 streaming devices today. It's a glimpse of what's to come.
