puneetvikramsingh: ISO performance is one stop better than my Nikon D5100....

@ ashwins - no doubt its asking for a lot, but chronologically speaking, looking at the gradual progression of sensor technology, from the days of the D3S to the D4, 5D III & 1D X of today... it is an imminent reality that higher MP sensors will produce cleaner results at high ISO's... whether of not Nikon have managed to achieve this is another question altogether... but I'd like to give them the benefit of the doubt until an official review...

Just 1 stop alone wouldn't really be an impressive feat with a FF sensor... I was hoping on the lines of at least close to 2 stops better than the D5100 / 7000 ... Perhaps close if not equal to the D4 ... We'll just have to wait and see...

Way too much noise reduction in the photos... even in broad daylight... fine detail rendered more like a pastel effect...

Overall not a bad effort at all... guess it puts it on par with the Samsung Galaxy S3... but just not the quantum leap in IQ i was hoping for...

Sony seems to have come a long way in refining their noise reduction technique... definitely one of the best performing APS-C cameras available along with the NEX 5N & X-Pro 1...

Wish Sony would implement their stacked CMOS technilogy into APS-C sensors soon... Redesigning & tweaking their existing wafers shouldn't pose too much of a problem... especially given the sensor market share they currently enjoy...

resuyaber: In dpr studio comparison tool i find ONLY one DSLR ( Nikon D800) have better resolution than Nokia 808 ??? Is there something wrong with my eyes?

But it will never ever come close to bettering the 5D III at high ISO, dynamic range, depth of feild, per-pixel definition and just sheer all round versatility...

Taking your theory into consideration, at base ISO its equal if not better than the D800 too at detail resolution & capture...

In reply to:

Michael Uschold: Hmm, no penalty for 24 vs. 12 megapixels? What about reduced frames per second due to more processing needed, what about more noise at high ISO due to pixel density. Come on guys, you know better.

Of course there's a severe price to be paid for the MP increase... the results speak volumes about current generation sensor limitations & per pixel light gathering capabilities... If your main aim is to use this camera below ISO 800 you'll be fine... any higher and you'll be relegated to point & shoot IQ...

Nikon's marketing department might allege great advances in noise reduction algorithms and sensor design without compromising on IQ ... take it with a pinch of salt... its all a load of rubbish...

On Just Posted: Fujifilm X-Pro1 review article (271 comments in total)

Its funny... but i remember reading Ken Rockwell's D800 review not too long ago... and in that particular review he included a high ISO image comparison between a number of current APS-C & FF camera's... two of which were the Fujifilm X-Pro1 and the Nikon D7000 ... and lo and behold the D7000 samples actually manage to look cleaner and retain better colour throughout the spectrum...

Now exactly how he managed to achieve that result is anybody's guess... Whether he manipulates the sample images with biased intentions or is his testing methodology just drastically different...?! Because from the DPR review one thing is abundantly clear... the X-Pro1 is definitely the best APS-C camera available for pure IQ... getting the better of a number of FF models in the process...

By any chance, is the high ISO capabilities of the D800E superior compared to the D800...?! At least from the RAW samples it certainly seems that way... quite a bit cleaner, with significantly less chroma noise and better detail retention... if this is the case... a very impressive feat indeed...

In reply to:

Tape5: Even Canon's top DSLR right now is a failure. Rebels have a tradition of being mediocre garbage cans producing mediocre images for years. Is this rebel any different? This is something for those people who give a damn to go and work out.

And i suppose you're trying to insinuate that Nikon or Sony's equivalents were actually superior in any form whatsoever...

Canon isn't exactly linear in its approach to Rebel series upgrades... sticking with 18 MP on an entirely redesigned sensor was a good move... and seems to be paying of in great dividents as far as IQ is concerned... even their revamped AF should be more accurate & responsive campared to Nikon's D3100 / 3200 & D5100 range...

Nikons decision to implement 24 MP on an APS-C sensor sounds like a massive upgrade (on paper at least) ... but even from sample images, IQ seems to be a notch or two behind their previous generation of DSLR's... colour rendition & depth seems to be muted for some reason... and noise... well its okay... but even Sony's NEX 7 is a cut above them...

On Just Posted: In-depth Nikon D800 review article (541 comments in total)

"Outstanding high ISO performance in both JPEG and Raw files" ... you lavish way too much praise on this camera... A more practical conclusion would be... good high ISO performance... but definitely nothing "outstanding" about it...

Even in DP's own image quality comparisons (both RAW & JPEG) ... chroma noise levels are a far cry from being "low"... the Canon 5D III & D4 do maintain a stellar degree of uniformity in their chroma levels... but not the D800... it looks boarderline unusable at 6400... so where is this blatant bias stemming from...?!

In High ISO Noise Comparisons (21) upscaling the 5D III image is very unfair considering native output is at a14 MP deficit... a better alternative would be downscaling the D800 image... This is the first review i've read where the D800's low light performance comes even remotely close to the 5D III at anything over ISO 1600... something is seriously wrong...

On Pentax K-01 studio test shots published article (146 comments in total)
In reply to:

marike6: These test show clearly the K-01 as the pinnacle of IQ for a mirror-less camera, equal or better than most APS-C DSLRs. The two Fujis, X-Pro1 and X100, NEX-7 and now the K-01 are as good as it gets IQ-wise in this class of camera.

Quite frankly i think that both Fujifilm's X-Pro 1 & X100 are grossly exaggerated... I mean don't get me wrong, they're both very good... which should be able to satisfy even the most discerning of critics... but definitely nothing "class leading" about either of them...

In JPEG, the Sony NEX 5N is the epitome of IQ excellence... When it comes to RAW... despite the fact that Pentax does manipulate the final output... i'd still say its an extremely close contest between Pentax, Canon, Nikon & Sony... with none of them being significantly better than the other...

On Just Posted: Olympus OM-D E-M5 review article (577 comments in total)
In reply to:

Tavi: I really don't see where E-M5 is behind the APSC, at least according to the results on the dpreview's comparison tool. The output is generally nicer or very close to many other cameras, including mid-range DSLRs.

The price is a bit high but after factoring in the camera's qualities (size, weight, lenses, sealing, customizability, speed) I believe it will be a strong competitor in the enthusiast segment.

Great job, Olympus!

On the "Noise & Noise Reduction" page (16) ... include the Canon G1 X in the test... the Canon beats the Olympus OM-D E-M5 along with all of the APS-C competition...

The grey & black levels are simply spectacular on the Canon... and the queens head is the clearest & best defined of the bunch all the way till ISO 12800...

injeklitio: look the samples in raw, focus in mickey mouse pants and set the iso 1600, the worse is the d3200, following d3100, cannon 600d and the better the d5100, too much mp for this camara, there is nothig new in the d3200, bad for nikon.

@ marike6 - come on... you have got to admit that the high ISO performance of the D3200 is mediocre at best... ISO 1600 and above is practically unusable even by amateur standards...

The Canon 600D is much cleaner in just about every aspect of the DPR sample image... look at the brush... the legibility of characters on the bottles & the Kodak colour chart... the cloth fibre... the blue clock... the womans face... & that patch of tiger skin... everything is rendered with realistic pinpoint accuracy...

And considering this camera is targeted at a segment of the market which will comprise mainly of amateurs... i doubt anyone will bother downsampling to reduce noise patterns & artifacts...

In reply to:

AnHund: Excellent post thanks. Tried down sampling the raw image to same size as D700 and the IQ is very close at ISO 3200 when doing a little post processing. This is just amazing for such an affordable camera. Bravo Nikon.

If you honestly feel that downsampling D3200 RAW files is any form of justification in somewhat equalizing IQ with the D700... then you have to admit that downsampling 600D RAW files to 12 MP will produces visibly superior results to the D700... (of course with a little post processing as you say...)

In reply to:

645D: Nikon is kicking Canon's butt in all directions:-) Keep going, Nikon!!!

But you've got to admit that the 600D (especially in RAW) is far cleaner and retains greater detail than the D3200 throughout the ISO spectrum...

the D3200 shots don't really look "out of focus" ... it just comes down to the fact that its a futile attempt at trying to design your own sensor and cram 24 MP onboard...

The D3100 seems vastly superior to this latest iteration from Nikon... better colour depth & saturation levels... noise levels are cleaner and better controlled... DR is probably close to a stop better too...

This just reinforces the sentiment that at the current state of sensor development, camera manufacturers should have realistic expectations as to what they can pass off as good IQ... without having to blatantly compromise on quality and performance... because quite frankly this new trend of massive megapixel increases doesn't really inspire confidence amongst consumers...

ARTASHES: To Dpreview or/and Dcresource : Have any info about ZS15's sensor?
Please

As far as i know, i don't think Sony ever produced a 14 MP BSI CMOS sensor...

Exmor R CMOS chips have been available in 10, 12, 16 and now 18 MP ... By the way they built it in 5 & 8 MP as well... but that was for the Xperia range of handsets...

I sincerely hope Panasonic swallows its pride and utilizes Sony's expertise at 1/2.3" sensor development just like Canon & Nikon have in their point & shoot range... If not, the FZ200 is destined for failure... assuming they use this same 14 MP backside illuminated sensor...

Direct link | Posted on Apr 27, 2012 at 11:08 UTC

The image quality is absolutely appalling at anything beyond ISO 100 ... very disappointing indeed... Panasonic should have stuck to the 12 MP sensor, such as the one found in the FZ150...

Canon seems to be the only company capable of delivering good IQ at high sensitivities, using a high density 1/2.3" sensor... such as the exceptional IXUS 125. I guess its got to do with their superior JPEG processing & Digic 5 combo producing great results...

By the way... Sony's new 18.2 MP BSI Exmor R CMOS chip seems like a very promising proposition... their DSC-HX200V delivers good IQ all the way till ISO 800... (visibly better than their HX100V) and thats saying something coming from Sony... which is infamous for their heavy handed NR & overcooked JPEG's...

OneThird: Nice pics! After owning a D3100 awhile back before I sold mine, the low light images are much improved, thanks to Expeed3 and the new 24MP sensor (from Sony of course).

Now, if Nikon can include these features, it would be a sweeter deal, IMHO.

-more than one custom white balance.
-Kelvin temperature scale.
-shoot with flash while dragging the shutter.
-Off, Low, or High NR at ISO 800 and above.

I think this is a Nikon exclusive sensor just like the one used in the D3100... for starters the dimensions are noticeably smaller than Sony's equivalent...

In reply to:

conphi65: DPREview, when giving specifications for video, give us the PAL equivalents as well please?

99% the 1D X will crucify the D4 ... you better hope that the 1% works out in your favour...

The D4 can't even beat the 5D III at high ISO by a decisive margin...

The D3200 will compete against the 650D ... not the 600D

The Coolpix L25 is better than the G1 X ...? Its good to dream... hopefully one day your dreams will materialize into reality...

In reply to:

topstuff: It's quite obvious that the sensor is Sony. To suggest otherwise is nonsense. It is totally illogical to imagine any other scenario, especially given the fact that Nikon have used Sony made sensors in the past.

But that is not the whole picture. Nikon will have their own processor and supporting tech architecture plumbed into the sensor. As a result, I think we can expect excellent IQ.

Nikon have already demonstrated with the D800 that they can make high MP sensors produce decent noise performance. The D800 is way too close to the 5D3 in noise performance than it should be considering it has 60% more pixels. The difference is not large. This means that the extra MP comes with little sacrifice in terms of noise.

Expect the cheap little D3200 to perform the same trick? Probably.

Well done Nikon.

Now over to you, Canon. What ya got ???

@ tkpenalty - Yes, indeed i have downsized the D800 files to an equivalent 22 MP... all that happens is that the noise artifacts get miniaturized proportionately... the level of noise is still the same but gives users the impression that its been reduced...

To use the term "outclassed"... is a very generalistic characterization and doesn't really tell the entire story... Yes the D800 resolves more detail compared to the 5D III from base till around ISO 800 after which the effects of noise & noise reduction pretty much level out the playing field and from ISO 3200 there is no doubt that the 5D III produces a superior image both in terms of noise & DR...

@ gsum - this link you've provided doesn't seem to carry out much of a professional quality test... in this particular case i'd prefer to go by reputed camera review sites such as the two i mentioned above...
