And now he'll have to provide a reason for the users to buy that, to compensate for the limit (which is a "con" by design)... seriously, how stupid a concept is that? And how can it be even implemented? I want to take a photo of my wife at the Tour Eiffel (yeah, the internet is full of photos of my wife at the Tour Eiffel), or an unusual wide angle shot from the bottom, or a detail of a rivet, and I can't?This is the stupidest camera concept I've ever heard of. This guy doesn't deserve an article here.
memau: It will not work out in the real world, even the co-author of the paper confirmed that modulo camera still comes short when the scene been captured just way too high-contrast. I guess to overcome the drawback the sensor coupled must employ something like overflowed counter that keeps the iteration counts of overflow. But think about it, why not just refines the conventional sensor?
Secondly, lots of people confuse the idea of "HDR", there are two components : 1) the ability to capture more dynamic range2) tweaking for display medium, because monitor or print just can't handle the dynamic range been taken
Modern camera now can capture 14EV, which means about contrast of 16000:1, obviously it's very hard to represent in print, so there comes Tone-Mapping.
This paper covers both the first part and second part, the fancy trick is the first part, but I don't think it makes sense at all.
That's how I actually understood this technology works: counting the number of overflows. "Why not refining the conventional sensors": apart from the fact that the sensor manufacturers have been doing this endlessly, I don't see why some researcher should not try expanding the concept.
Why should it? It would simply not "overflow" any pixel and the readout would be same as the current sensors. This research shows a proof of concept for a new technology, but it's not THE new technology itself; applied, that is. All the other factors (sensor quality, color fidelity, noise, base DR without overflow etc) are out of the scope of this research afaik.
"Useless" is a big word, compare it to today's way to do HDR and I see a big difference there already. Then if you don't like the results, it's your own personal taste, which makes nothing "useless" anyway. The fact of having an image with better DR helps where another camera would have got flat out black-white in some unrecoverable areas. It doesn't mean the image will look all flat and with typical hdr-unrealism. You can do whatever you want with a HDR image.
Leica full frame compact is DEFINITELY NOT the most interesting news in the week, and by a vast margina I'd say...
Paul Grupp: Any serious hobbyist or professional who thinks that it's worth switching to another platform just because Adobe rents a combination of Photoshop and Lightroom for a measly $9.95/month is either just playing around or being flat-out unrealistic. I get it -- some of us would prefer to own the software. Well, that's not on the table. The question is, if you are serious, is $9.95 a month really burdensome? Not even close. And if you have invested hundreds, maybe thousands of hours in learning the ins and outs of Adobe products, switching to something else because you think $9.95 is too much to pay is being penny smart and pound foolish.
I'm in europe and for the photography package it asks 142 euro/year. First of all, I dont want PS, I want only LR. Two years of usage make 284 euro. I'm spending less with the full version and upgrades. End of discussion...
About Exposure latitude comparison with A7R, the A7R wins hands down when iso is low. but for example iso 1600 + 2 stop or iso 3200 + 1 stop (much more common cases) the A7S looks better to me
Franka T.L.: Unless there's something magical about that sensor I fail to see a point here
The original post might be vague or no value for you, but I understood it like s/he didn't get the point of this camera and I provided a clear reply. The word "magic" was obviously referring to "I don't understand the value of this camera, unless it's a spectacular sensor" but you keep replying as s/he truly believes in magic and you're building a castle around it...
What a useless and arrogant answer, JDThomas... and 4 people liked that?.. Aaaanyway, the point here from the user perspective is to provide a rangefinder-like focusing system (overlapping images) but in a digital format seen on LCD. "Cheaper", according to them, due to the lack of mirror and prism inside the camera.You can see an example here:http://petapixel.com/2015/02/23/konost-hopes-to-launch-the-worlds-first-true-digital-rangefinder/
fuxicek: back in film days I used compact minolta http://www.amazon.com/Minolta-Freedom-Zoom-150-camera/dp/B0000AUFK7.. I wonder, how did they squeeze the full frame into tiny body with tiny lens and why its not possible with digital?
1. It's not a dslr (and is it that smaller than the sony a7)?2. That lens: 37.5-150mm f/5.4 - 11.9, 6 element/6 group constructionWell... you get what you paid for I guess? :)
It would be interesting to see some image at base iso 200

StephenTee: It was recently commented that at a given ISO of 3200, a longer exposure was needed for the Sony RX-100 II than the Fuji x20 (1/8s vs 1/15s for roughly the same f-stop).
However, since the RX-100 II "base ISO" is 160 vs the Fuji's 100, you could claim that it's expected for the ISO or exposure values to be about 2/3 different in the exact same light/exposure conditions.
Again, not really. If you set the iso 3200 on both cameras, what the "base iso" is doesn't matter. It's just 3200 for both sony and fuji. My observation was that you can't compare them on the same ISO value when the other values (F, speed) turn out to imply that sony needs to get more time, hence possibly needing a further ISO increment
Causio: I just noticed that the RX100 II overestimates ISO to the point where - being iso the same - it shoots at half speed as the Fuji X20. You can download the night shots at iso 3200 for both and check yourself: Sony is 1/8 sec f5, Fuji 1/15 f4.5. Sony shot at iso 6400 brings it at 1/15 sec (f5). Even considering the tighter aperture, sony overestimates iso more than Fuji does (2/3 stops?). In real world, this would translate as shooting at lower iso with Fuji, being the desired speed and aperture the same.It would be nice if dpReview made people notice in an OBVIOUS way on their comparison pages, that there is some iso overestimation going on for all cameras, and varying from model to model.
Doesn't make much sense, at least explained that way. I can reply that it needs more light because the sensor is bigger... if you put the same light received at the same time by a smaller sensor, distribute that amount of photons all over the bigger sensor and the photo will be darker. Hence, it captures more light because it is physically necessary for achieving the same exposure. And guess what? The sony needs in fact LONGER...

JohnMatrix: Does the screen flip past 90 degrees? i.e. can the social media slave who uses this camera easily take a picture of themselves?
I think you can use your phone for that, with the canon app
tommy leong: can this do self portraits?the entitlement generations MUST have....
I think you can use the phone app to use it as a remote - including framing.
Charlie Jin: I don't think that DPR really understood the purpose of theweight of K01. It was intended for "professional feel". ;-)
So what's the point of a mirrorless camera then? The decision of making this camera compatible with slr lenses defies the whole mirrorless idea. Except for Pentax's marketing department very personal idea of product design, the only thing they achieved here is lower price. So basically they invested a lot of money in defining the Q standard (with new lenses etc) and couldn't afford to define another mirrorless standard with other lenses. And about the design, this is gadget-thinking (even the designer's signature is there... good for his reputation isn't it? :D), not camera thinking, yet with pro-quality expectations (including buying more "serious" lenses for it). Weird to say the least
Dave Peters: Not compatible with Lightroom 3 ? So I can't load my existing catalogues and even if I re-import the photos to a new catalogue they will appear different and require reprocessing. I think forward compatibility is an essential feature. They should have kept all the old processing routines so that the program could detect old files and show the images correctly.
The release version can now import LR3 (and older) catalogs.
