Great - but only for fixed-focal length-fixed-sensor cameras like those in phones/telescopes etc. No zoom lens or interchangeable lens.

Unless ...What would be interesting would be a shape memory alloy back plate for the sensor which flexes/curves to varying degrees with the application of an appropriate electrical current. The engineering precision would be quite incredible.Maybe calibrated curvatures for common focal lengths in steps like 24mm, 35mm, 50mm?

Peiasdf: I think the most amazing thing is SONY hired so many people to run and jump for reviewers to demonstrate their flagship and latest tech while Olympus fly people out to Iceland to shoot snow and gray sky using E-M1 II

How do you know Sony "hired" people?

They looked like ordinary amateur sports folks training away. Some looked really ordinary, certainly not Olympic grade celebs.

dpreview44: wow 120fps.. double the refresh rate of Fuji

Funny how the Nikon Guy cannot stick to the Nikon forums... Canikon fanboy...

@HenryDJP, you're obviously not cut out for the FF league. Stick to the micro 4/3 forums.

ZJ24: This is not a comment on which is "better", EVF or OVF. I think though it's relevant to point out that if you want to win over all the Canon and Nikon sports shooters, you need to acknowledge that they all currently shoot using OVFs. It's a little like pointing out to motor-heads that your Tesla accelerates faster than their Ford - you might be right, that doesn't necessarily mean they want to embrace your tech. The other obvious issue is at the long telephoto end. The 100 to 400 zoom looks very good, it's just not what that market uses primarily, if you are talking about full time sports professionals. Again not a comment on the quality of the release, more on those who seem to assume everyone's going to be dumping their current gear to join Team Sony.

Well what did we not know already. Some people never learn and never want to learn.

They will be losing shots chimping on their rear LCDs due to their OVFs. They are the ones missing shots due to the wrong exposures precisely because of their OVFs. And they will lose images and their jobs precisely because they are only seeing what their lenses are seeing.

I have no issue with them messing up at all, except that these are the same fools putting money and resources into obsolete tech by failed companies that do not want to innovate. Which only bothers me off since such misdirection of resources is exactly what is killing the planet.

KLO82: It seems to me that there is huge difference in philosophies between Canon and Sony regarding their imaging products.

In Canon's view, all the problems/ limitations in photography have already been solved, the technology is matured. There is no need for anything revolutionary. Just fine tune/ slightly modify your existing products and reiterate them - and ensure the reliability of the products. If you still can not get your intended photographs with the current products (cameras and lenses), may be the limitation is you.

Whereas in Sony's view, there are still many more limitations/ problems to overcome in imaging - there is much to be done.

Eventually, we will see who's view is closer to reality.

But Sony needed the revenue & profits from Nikon to fund R&D while building the Sony mirrorless brand. Hence they sold their best sensors to Nikon for the D800. Now Sony can't even keep up with demand for its own products - look at the waiting list for all their most recent A7 & A99II - they have said they will not supply their latest gen sensors to 3rd parties anymore. Even the Fuji GFX uses Sony's older gen sensors with poorer DR and IQ (albeit just larger).

Now that Sony has turned the photography industry into a truly electronic-digital-silicon business it was meant to be (all mirrors, shutters and mechanical motors - gone), the Canikons/Canikonians still don't get it. They are still not innovating.

So much for history repeating itself. Photographers are some of the dumbest consumers in the world.

Circa 80s/90s, Canon saw the importance of removing all the mechanical gears and drive trains connecting autofocusing motor in the camera body to the lens with the electronic EF mount.

What held back that revolution in the market? Stupid consumers like the Nikonians in denial who believed what Nikon was peddling to them . Remember their refrain? Who needs fast autofocus? The best photographers manual focus! Duh...

Nikon lost most of their pro sports market to the Canon white lens phenomenon.

Then when Canon made the 1st full-frame sensor, the same denial from Nikon/Nikonians. Who needs full frame? That was when they lost the whole market. If not for Sony selling them sensors for the D800, Nikon would have been finished.

badi: "But that feature, that incredibly fast readout speed of that new 24MP sensor, is something you're paying for if you shell out $4,500 for this new camera, even if you're only interested in the other (not insignificant) improvements outlined above."

Carey, that is entirely wrong, so wrong that you might want to rephrase it.
The fast sensor readout helps in a lot of other things, and at least two of the most important others that you stress: The (almost no) rolling shutter - is due to that (important for stills with ES but also video). The continuous live view feed during the bursts, is also due to that (because there is no other sensor that sends the image to the viewfinder while the main one is recording an image).

Exactly why I said there ought to be more competent and interested reviewers writing for DPReview.

This is a blogger piece by a lazy person who didn't even bother to read the product specs or literature or watch the live announcement streaming video (or its recording) where the legendary and eminent "real" photographers spoke about their use of the A9 months before the launch. 2 of them having 40 and 50 years experience respectively.

The 20x faster readout speed is the key enabler making the A9 the world's first pro camera with a de facto universal global shutter. This speed is what allows the 1/32,000 sec shutter speed. Doubt this Carey person understands what it means - You will need/appreciate it when shooting f1.8 or f2.8 in bright tropical/noon/winter light without having to carry bulking ND filters or losing highlight details with fake ISO 50 or 25 expansion options.

Also - no jelly rolling shutter distortions in BOTH stills or videos using this noiseless electronic shutter!

Dr_Jon: The e-mail I got from a dealer on the A9 said:
"now thanks to in-built RAM can handle a phenomenal 20fps in continuous shooting mode with AF/AE lock"
Is this true and there is no AF or AE at 20fps?

Ditch the dealer. Is he a drug dealer?

dash2k8: Can someone confirm if the Sony Eye AF is the same thing that Canon had in the EOS-3 from the 90's? I believe it was called the Eye-Control system.

The A9's EVF and sensor plane PA AF is critical to this accuracy - there is simply zero back/front-focusing issue with any Sony A7/A9 system unlike DSLRs.

But its the scene interpretation intelligence that is unique to the mirrorless-EVF paradigm. The A9's brains need the constant 60fps or 120fps data feed from what the EVF is reading to interpret the context of the nature of the scene to first figure out whether the subject is a person or a tree before deciding to locate and track the subject's eyes (if it is the former).

It's also automatic - you can choose to frame & compose the shot, which gives critical focus while leaving the photographer free to mind the other creative aspects of nailing the shot. Not since the advent of auto-focus has there been such a useful offloading/automation of such menial tasks as autofocus.

The applications are vast, especially for people photography and portrait work, whether in the studio with rapid model posing or fashion runways.

Canon's eye-tracking of the photographer's eye is outmoded and irrelevant. What happens if the photographer looks at the bottom of the viewfinder to check the exposure level bar or the edges of the viewfinder for framing etc.? Then assuming the tracking of the photographer's eye works, the focus on the subject will be lost.

Sony's eye tracking of the subject is much the same as your Android/iPhone's face/head tracking - but with much finer precision to track the subject's eyes, as befits its much higher sensitivity and density of phased array AF points, all 693 of them covering 93% of the viewfinder.

This is only possible via the said PA sensors on the same A9 CMOS sensor plane, not reflected up a mirror into a separate PA sensor perpendicular to the sensor plane like outdated DSLR with century old pentaprisms-periscopes. There are so many white papers detailing the limitations of DSLR PA sensors, including the notorious back/front-focusing issues for EVERY LENS-DSLR BODY COMBO.

zakk9: Please explain this to:
Olympus E-M1, which at $2,000 has been critisised for being expensive, has similar specs, apparently better weather sealing, fully articulated LCD, dual IS and uses USB-3 vs. the USB-2 on the Sony. How is the larger sensor and lower specs of the A9 worth $2,500 extra for a camera that doesn't even offer the long lenses I would need shooting sports?

Try educating yourself on what a full-frame sensor is. Please don't waste our time if it is too far out of your league. Keep your comments to the micro-four third forums.

Every Crook and Nanny: I honestly don't get a lot of people. They treat brands like they are sports clubs, putting down users of other systems and using words like " Canon/Nikon/Sony fanboys", "DSLR killer", "the final nail in the coffin for C/N". Why should you care what others use? I think that the A9 is a marvelous feat of tech and it would be interesting to see it put through the wringer. Stuff like this drives competition and improves the overall level of imaging technology. It's never a good thing if brands die out and only a single brand is left to monopolize the market.

Also, why are DSLRs considered obsolete/dinosaurs? Did everything suddenly become too difficult for DSLRs to take pictures of? Truth is, we are absolutely spoiled with what modern cameras are capable of and if a Speed Graphic can still take jaw dropping pictures, I don't see why a DSLR can't. We all should be happy with the immense selection of camera bodies and systems we can choose from.

Isn't modern technology wonderful?

It is a great thing if uncompetitive companies that make obsolete stuff die out... it preserves precious resources.

Watch the A9 announcement live streaming recording - the expert panel talked about how they didn't even realise how Sony has changed photography's pain points until they used the A9.

The pros and the non-pros will learn something from their accounts.

In reply to:

Kubicide: Folks need to remember all we know right now is what the Sony marketing machine is telling us. Probably best to wait for the hands-on reviews to truly determine how good/bad this new release really is.

Some items are potentially over-hyped like the stacked sensor which will minimize rolling-shutter distortion but not eliminate it. So what will results look like when panning at high rates which would be common with big glass. Also will the stacking affect sensor heat and will the long exposures be decent or suffer from glow? We don't know. And is the AF improved at all? On-chip solutions still lag behind here. But something one can probably expect to see is trade-offs. Nothing is perfect. This camera won't be perfect. So what 'give and takes' will this new body bring is still unknown.

Will be interesting to look back at the comments here after we see a few reviews and have some facts revealed.

Learn to read. Or as a twitter-instagram-facebook gen twit, watch the live announcement recording of the expert panel's hands on experience relating how their work will be changed forever by the A9.

The stacked sensor is basically the universal global shutter Mk I. 20x readout speed. Rolling-shutter has been eliminated. 1/32,000 s shutter speed. The electronic shutter that is completely silent (though you can add a digital sound if you wish for feedback, see Brian Smith talking about it) ) will never wear out and never need replacement unlike your Canikon.

The expert panel vouched for the focusing speed, which includes a Pulitzer prize winner, a Reuters guy (40 yrs photography experience), a legendary photog with 50 yrs experience, a Nat Geo land/underwater photog, a press/war photog, MMA photog.

You dinosaurs just dun get it. The A9's focusing speed is limited by the speed of silicon. Not by the interruption of a flipping mirror box blocking the focus sensor for heaven's sakes.

MistaHaid: With an optical viewfinder you can observe your scene over a long period of time and wait for the right Moment without loosing battery or heating up your Sensor. Thats important for me. Besides that i think this camera brings a lot new Life in the camera Industry.

The dinosaurs do not get it. Never will. They can't see the forest but they only see the tree and keep harping about the tree.

This is the kind of idiocy the Canikons say. Oooh I need to put a huge chunk of metal and glass to my eyes in order to see with my eyes. They still don't realise that when they put that chunk of gear to their eyes, they are only seeing what the lens is seeing, not even close to what the camera is seeing. That's why they have to chimp.

Which is why I recommend everybody watch the A9 live streaming recording. The expert panel basically explained the real life impact of what the A9 can do, which is what I have been saying for years on DPreview about EVF and stuff. They very amusingly talked about pros chimping and missing shots in the history of digital photography!

These are the clowns who don't realise that they are using century old American Civil War periscope-pentaprism tech developed for the film era. You want your OVF, shoot film... duh.

leewardism: I have to say, where would we be if Sony had not entered the DSLR realm, would we have even got to 14 megapixels by now?.

@thx1138,

Just because @leewardism used some specs like 14 mpx loosely, does not mean that you should throw your ignorance about.

Sony got into the DSLR business specifically to change it so that you do not have to live under the yoke of incremental same old same old periscopes-mirrors-mechanical shutters year after year.

They got into the DSLR business years ago by acquiring Minolta. They had the A850/A900. But what they really did was focus on the semiconductor/electronics aspects of the digital era photography.

Which many still don't (or won't) get. Are you one of them?

Nukunukoo: Because of it's extremely fast readout speed, I expect it to be close to the performance of Global Shutter sensors.

Perhaps you've been using the Olys and Pents too much that's why.

Learn to read. Or view the samples. Or understand engineering facts. The stacked CMOS sensor reads data so fast, there is no rolling artifact. That's what I meant about those who just dun geddit... lol.

Ran Plett: I don't get the intense fanboiism.

Do you guys realize that the intensity of brand loyalty (and the staunch need to defend it) is inversely proportional to the skill, creativity, and passion required to be a good photographer?

I have absolutely no loyalty to any brand. I only care for knowledge and hard facts Which a lot of folks do not seem to grasp.

What aspect of knowledge, facts, skill, creativity and passion befitting a good photographer did you display with your post though I wonder?

AndroC: How do these small bodies go for people with large hands like myself? And with big long glass mounted? Any views?

See how the people will do anything to scrape the bottom of the barrel?

Give them a Van Gogh and they will crap that they don't like the colour of the frame its mounted on.

Sure, I bet you're one of those who will then say... if I use a heavy lens, I want the body to be even heavier to balance it out! Lol!

Read properly! Its already been enlarged for the larger battery! There's also a vertical battery grip!

Else there's also a grip extender to make sure that small hands, large hands will all fit! This last point is quite ingenious. For every idiot who says he has larger hands, there will be another one who claims to have small hands. You can't shave a Canikon down can you?

Another huge plus of the small mirrorless body - you can customize it to be larger, but not the other way round with a big body.

User9362470513: Why are so many photography fans such repellent, one-eyed dicks?

So Sony announce an impressive camera and people revel in the thought that it might mean the end of Canon and Nikon etc. Why such delight in the possible demise of another company? The schadenfreude is appalling. Are you really so insecure about your choices in life?

I have used Canon, Nikon, Sigma, Sony and Ricoh cameras. I wish them all well. They all make exceptionally capable cameras and the more brands in the market, the better it is for consumers.

I think a world where everyone is limited to one or two camera brands would be a disaster. Weird that so many fanboys on here seem to think it would be nirvana.

Nope, its because photographers are the dumbest kind of consumers. History has shown it to be so.

Remember how in the 80s and 90s, the Nikonians always said that quick and silent autofocus isn't important and necessary? Nikon almost lost its entire pro business to the "white lenses".

Remember how Nikon said that full frame high res 35mm sensors weren't necessary either? They really lost all their pro business there!

Even now, see how in this digital era, the American-Civil-War-era-submarine-tech-periscope-pentaprism-huggers (or what you'd call the Canikonians-dun-gedditters) insist on mechanical flippin mirrors and shutters?

All so that with the OVF they can only see what the lens is seeing, a la the film era?!?

Whereas the rest of the world have moved on to REAL-TIME DIGITAL IMAGING? In other words - seeing what the sensor is seeing? Its not just Sony, its the other mirrorless players too.

But believe it or not... the dinosaurs will not want to admit it. Observe and watch.
