Why can't Nikon introduce a new 1 series camera utilizing Sony's 20 MP 1" Exmor R sensor...?! Or could it possibly be that Sony simply won't license the rights to that sensor to Nikon at the present time...?!

chouster: What can be seen here is that the Nikon D7100 is the best APS-C camera.

@ chouster - your statement even contradicts DXO's findings... where apparently the D5200 is the "best APS-C DSLR" ... but Nikon's probably got DXO on their payroll...

Nobody's denying the D7100 is good ... but give credit where credit is due... the 70D is easily as good... if not better...

Even dpreview's studio sample scene clearly demonstrates that the 70D captures practically the same amount of detail plus retains it better all the way up the ISO ladder...

Look at all 4 peoples face in the test scene... the 70D definitely delivers the cleaner, less noisy set of images...

James Booba: hm 70D doesnt even comes close to a nex-6 in higher ISO ... meh.

So it would be safe to assume Sony is light years ahead of Canon in sensor design... best solution lets stop buying Canon cameras... :)

Its obvious even to the untrained eye... Sony is applying NR in their RAW files... Look at the sketch of the old bearded man... Canon & Nikon's samples are much sharper...

Very impressive noise performance... clearly leaps & bounds ahead of the 60D / T5i ... JPEG definitely looks cleaner than the D7100 ... albeit ever so slightly softer... D7100 image looks speckled with chroma noise for some reason...

In reply to:

CNY_AP: What I don't understand is that the Nikon 5200 for example is highly rated by DxoMark, but when I look at high ISO shots in the Comparometer tool, I think the various Canon 18MP sensors fare well against the Nikon (in terms of detail retention versus noise).

Better example - Nikon D3200 is very highly rated in DxoMark, but in the T5i review, it looks awful. The review says so, not just me:
http://www.imaging-resource.com/PRODS/canon-t5i/canon-t5iA.HTM

http://www.dxomark.com/index.php/Cameras/Camera-Sensor-Database/Nikon/D3200
http://www.dxomark.com/index.php/Cameras/Camera-Sensor-Database/Canon/EOS-700D

So I wonder if DxoMark doesn't measure sensor performance correctly (wrong methodology). For example, maybe Nikon simply blurs their images more, hiding noise, but losing detail.

Or maybe Canon has superior firmware/processing which overcomes/hides their sensors' inferiority. But in the end, if the images look the same, what does it matter.

And exactly how do they carry out this analysis of the demosaiced RAW files...? By applying their in-house reconstructive interpolation algorithms...? Or do they strip the sensor of its internal circuitry and scrutinize its SNR ratio through external amplification...?

lensberg: DXO might serve as the holly grail for the average Nikon fan... but their "supposed tests" hardly serve as any meaningful purpose in determining which camera / brand is the best from an overall performance point of view...

DXO's only real purpose seems to be that of a proxy for Nikon's marketing department... to give the average joe something "scientific" to go by... Plus they should add a camera quality score... something where Nikon's D600 / 800 would score abysmally... oil spots and dust galore...

Best method of determining which camera is best suited for you is to read a broad spectrum of reviews across the web to formulate your own nonbiased opinions... Or just walk into any camera store and get a first hand account for which body suits your best...

@ Shunda77 - The D5100 / D7000 may outclass Canon's previous generation 18 MP sensors - but there's no way that can be said for Canon's new 20 MP sensor...

Canons new dual pixel sensor is definitely on par with the Toshiba variant found in the D7100... and quite frankly it looks slightly cleaner at high ISO's in RAW... I'm not the only one saying it - camera review websites that have conducted initial tests are confirming it...

Granted Canon isn't as good as Nikon where dynamic range is concerned... but come on, the differences aren't anywhere nearly as drastic as earlier years...

@ Collie Camp - 5 years ago wasn't the D300 considered better than the Canon 50D ... Why would Nikonians have made a comment like mine...? Was there some underlying uncertainty that the D300 wasn't as good as claimed to be...?

In reply to:

igor_s: It seems that the 70D owners will have described everything before the review appears. Actually, 70D = 60D + on-chip PDAF, which is the only thing to investigate given the available sensor performance test results from DxOMark.

And what is the D7100 exactly... a refurbished D7000 + a Toshiba sensor - the OPLF...?

Since DXO seems to have been in a tearing hurry to demean the 70D ... why don't they at least provide conclusive samples or evidence of their testing to substantiate the random numbers they put forth... Just to add an ounce of credibility to their name...

igor_s: Well, I think now everybody will admit that the 70D loses to D5x00 and D7x00 in SNR, the difference being, at my sight, 0.5 to 2/3 stops ISO. Is seems to be on par with 60D, which Canon predicted.The sales will depend on how useful its new AF system is.

I was actually comparing the RAW samples here on Dpreview, plus imaging resource & ephotozine - The later two especially show that the 70D has a clear advantage in high ISO image quality.

To be absolutely honest I don't fully trust the veracity of cameralabs samples... and this apples to numerous cameras across the board that Gordon reviews...

Something is seriously wrong with DXO's testing methodology... 5D III was cleaner than D800 at anything above ISO 1600 ... The 6D was cleaner than the D600 and now this... but they seem to always favor Nikon completely irrespective of real world results / usage...

The 70D easily looks as clean, if not cleaner at high iso's compared to the D7100 - scrutinizing RAW & JPEG's side by side...

If you or DXO can honestly state that the 70D is "noisier" than the D7100 than there is either something wrong with your eyes or mine...

Alas wish there was some other alternate sensor testing website to at least provide us with a second unbiased opinion...

A hypothetical argument... I wonder how much DXO will score this new Canon sensor...

I'm guessing about...

Color Depth - 23.6 bits
Dynamic Range - somewhere between 12.5 - 13 evs
Low-Light ISO - 1150

All scores lower than the D7100... since traditionally according to them, they never mark Canon higher than their Nikon counterparts... Wonder if I'll be proven wrong...

Quite frankly the image quality is one step short of horrible... even a point & shoot like Sony's WX 60 / 80 which utilizes a 16 MP sensor is miles ahead in terms of IQ and noise control...

Frank_NZ: Like to throw in an unofficial competition for supporters of this site. No prizes to be awarded but here it is for your thoughts.

What do you think the final rating from dp review will be for the Canon 70D ?

For the record, my guess is 87%.

I do not know any of the staff or reviewers of this website so do not expect to be as close as some of you out there. Closing date for entries soon. Good luck.

Probably 85% ... after all everyone, wants to keep it competitive with its arch enemy the D7100 ... :)

Looks as good as the D7100... perhaps even slightly better in RAW... a contentious point nevertheless...

I guess it depends upon each individuals personal preferences to noise reduction... As is the usual story... Canon's image is cleaner... albeit slightly softer... Nikon's approach is grittier / noisier giving the semblance of slightly better detail retention... but these differences are mostly visible from ISO 6400 onwards... which should pretty much be your limit when using an APS-C sensor...

Considering they share the same sensor & processor... why does the D7100 score slightly more than the D5200 in DPR's conclusion - category - RAW image quality...?

In reply to:

RichRMA: Looking at the high ISO samples and test images, it's clear that 24MP is pretty much the limit for an APS sensor. They should probably stop at this point and wait for the technology to catch up a bit.

The Canon 7D may be the company's flagship APS-C camera... but the fact still remains that its 4 years old... One could argue that its almost 2 generations old... so making a comparison with Nikon's latest & greatest camera is not at all a fair comparison...

Wait till the 7D Mark II is out... probably sporting a 24 MP 1.5 crop factor chip... then we'll see just how "good" the D7100 really is...

Zalan: Could be my next purchase, I hope there will be a complete review soon :)

Unless 4 second delays between the P7700's RAW capture amounts to excellence...

Canon has always been miles ahead in the lucrative compact camera arena... and i doubt this trend is likely to change anytime in the near future...

It may marginally be ahead in certain areas... but can it beat the S110 for image quality...? The G15 was always superior to the P7700 for pure IQ... in both RAW & JPEG

Earthlight: It is a world class lens.

Now they only need a sensor to match. :)

One would imagine that Nikon's AF-S Nikkor 24-70mm is any better... in fact the Canon edges ahead in centre & corner sharpness...

In reply to:

jackpro: Very good high iso result trounces canon big time nice

If you mean that miniscule high ISO advantage actually amounts to "trouncing" ... then obviously our definitions deviate...

Its funny the way you're comparing a 2013 sensor to a 2009 one... Just considering the fact that they can actually compete against each other with the D5200 barely getting the better, speaks volumes about Canon's imaging prowess...

One would only notice these fractionally cleaner results at around ISO 12800... at which point you'd soon come to the realization that an APS-C camera, no matter how good, is not going to be providing you with an acceptable level of image quality ...

On Just Posted: Canon EOS 6D In-depth Review article (530 comments in total)

This nagging perception that Canon sensors are in anyway inferior to their Sony / Nikon counterparts exists only in theory... and is primarily propagated by DXO...

Despite the extravagant ratings that DXO awards Sony sensors... the reality is that Sony camera's doen't even come close to touching Canons image quality... in both RAW & JPEG...

Isn't it miraculous with Toshiba's foray into sensor development... Nikon manages to catapult that maiden sensor to take the top spot amongst DXO's APS-C sensors... considering the fact that noise is eating away at detail beyond ISO 3200... talk about bias...

The 6D is an outstanding camera as far as pure IQ goes... The level of captured / retained detail in anything from 12800 and above is simply awe inspiring... Personally i'd rather have better noise control compared to better dynamic range... Nikon in true fashion try to give you the best of both worlds - a jack of all trades... Canon on the other hand is the master of noise control...
