Even from jpeg I can bring the soil in the flower pot up four or five stops with no noise what so ever, but then of course despite this being of a white cat in the mid day sun the total EV range from highlight to deepest shadow is only around 6 stops, and that is accommodating for the intense reflection from the white fur.
The intense reflection is blown, actually.
You haven't down loaded the compress file from CR and try to read the highlights have you ?
Another faux pas ?
Yes, stop doing them.
I downloaded what you posted. There is a blown spot on the forehead of the cat. It does not matter what the RGB values are. They depend on the processing.
Why don't you post the JPEG from the camera before you start blaming it on the CR compression? That will answer the question.

It is interesting how real world experience can change our beliefs. The DxO experts have everyone believing that Nikon produces better color.
its interesting how people can make a statement like this
no mention of color profiles, contrast curves etc
Yes Nikon has the advantage of a better color filters CFA, you just have to take advantage of that
I call this knowledge
if you like nice colors from beginning and strait out from the camera and for your eye pleasure , buy a compact camera
they are optimized regarding contrast curves and color fidelity and s-rgb
I'm surprised that so many member show so much ignorance regarding SLR cameras , color handling and what the out come are for
unfocused said:I'm sure I'll get flamed for this and maybe I'm missing something here, but when I compare the D7100 to the 70D and 7D on the graphs there doesn't seem to be all that much difference.
I admit I'm not a dynamic range freak, and I'm more interested in ISO performance, but it doesn't seem like there is any real world difference between the Nikon and Canon sensors.
My conclusion: The 70D sensor offers an almost imperceptible improvement over the 7D and the D7100 might be an equally imperceptible improvement over both the Canon's but not enough to make buying a camera based on the sensor alone worthwhile.
For all the talk about how antiquated Canon's sensor tech is, I'm not seeing it in these results. Even their summary (if I read it correctly) says the Canon and Nikon sensors are only about a fifth of a stop different in ISO performance. One-fifth of a stop?
Okay...I'm waiting for the flaming to start.

That is often true, actually. In the audiophile world, big companies are not big, for example.

Please let us avoid statements like that Canon has better color reproduction, it is not true
on the contrary, they are worse because of the color filter, which is shown by DXO measurements

Really - what's that? It would be interesting because the Magic Lantern people are always interested in ideas on how to enhance the Canon firmware, but unfortunately most people lack knowledge of both systems (you do know Magic Lantern, right)?

It isn't that the 5D III was used incorrectly. Fred Miranda was the one who did that review, and he is a respectable authority on such matters. The original sample images were shot to keep the whites from blowing in a high DR scene...and this, quite plain and simply, is indeed the result when you lift the shadows to compensate. There isn't any question that Canon has issues with their low ISO DR. It has been blotchy and banded for well over five years now, and it is Canon's weakest point.
Given DXO's review of the 70D, it's clear they have not put any effort into improving sensor IQ. Canon's focus is clearly different, and the weight of their focus has clearly shifted heavily towards video. I was hoping to see a better DR improvement for the 70D, and these results are rather disheartening. I'm a stills photographer, and I use my DSLR for still photographs. Quite frankly, I would really like to see Canon invest some of their huge cash flow into improving their products for their primary intended purpose, and not some secondary "sometimes convenient" purpose like video.
The Magic Lantern crew proved that Canon's sensors are capable of capturing the full 14 stops of dynamic range allowed by a 14-bit ADC...I think its high time Canon stopped their focus in video and returned their focus to EVERY aspect of IQ, including factors based on the sensor. I've argued in the past that there are other factors that affect IQ, such as AF system, but Canon has already perfected those technologies. Fred Miranda's comparison of the 5DIII and D800 is an excellent demonstration of why Canon should finally shift their focus back towards improving still photography IQ. I don't even think the problem is in the sensor, either...I think its in the ADC...and Canon pretty much whips up a new version of that every major release cycle anyway...so there shouldn't be any reason they couldn't invest some serious R&D into solving their low ISO IQ problem.
No more clever arguments from me about why Canon's products are good. They are, but that isn't the point any longer. I truly hope to see something significant on the sensor/ADC IQ front with the 7D II...otherwise, the 5D III will probably be my last Canon DSLR purchase until they stop focusing on secondary video functionality and refocus on the primary purpose of a DSLR: photography.

Man the Nikon 70-200 f2.8 VR 2 sucks, like, those corners are terrible. To think that Nikon shooters have been wasting their lives with glass like that for so many years, almost half a decade now, sheesh, and it's so obvious too. It's like they've all got their head in the sand or something. I mean, obviously whatever talent you have is being severely limited if you use that system.
yes, the 70-200/2,8 VR2 is not the best regarding corners and together with a 24x36mm sensor, it is like a lot of lenses soft, and compared with for example Canon 70-200mk2 is the canon is much better
Now , it is not the only lens Nikon has, like Canon they have several and with better corner sharpness
Not the 24-70 2.8 though or 70-300 either.
Eventually if it really finally seems like Canon truly will never bother with more DR for another decade or two, I will switch, but I'd rather not if I don't have to. I'm starting to almost feel like it might be another decade for them or more. If the next round doesn't do anything for DR I wont buy it and will probably stop moving up in lenses, perhaps even dabble with a single lens and a Nikon as a second body and hope there is some sign the 5D5 round will do it, if it looks like not then I might finally switch over (keeping 5D3 and a simple lens or two for video if Nikon hasn't gotten anything going for video by then).
You'd actually switch over 2 stops of dynamic range? If Sony started making sensors with 20 stops of range that would be another thing, but if they stick at 13 (on average) and Canon stays around 11 (again, on average), that seems like a pretty minor issue to me.
If you look at the two flagship models, the 1DX and D4, it's only a 1.4 stop difference. Is that really such a huge lead? Heck, if you look at the variation within Nikons own current production models there's almost as much difference within Nikon as there is between the worst models from both companies.
Heaven forbid someone use a D4 instead of a D800.
Of course all else being equal it's a clear choice, but I have a feeling it'll never come to that, at least not within my lifetime.

And yet, do we see Nikon users, 10 times a day, 10 times an hour, beating the beejeezus out of Nikon on the Nikon forums for the wide open corner performance of this lens? Do we see Canon users dropping in on Nikon forums and chortling arrogantly, and constantly posting pics of comparative wide open corner shots?
Why not? Is someone, somewhere, having an attack of courtesy?
It is why I started this topic
http://www.canonrumors.com/forum/index.php?topic=16691.0
People are fixated on sensor performance, and then mostly on DR.
I am not really sure if there are Nikon users in these forums only to bash troll and attack, If so it is rather sad.
Now we just need to learn how to spot and ignore them, If no one replies to their posts their fun will be over really fast , they might even leave for an other canon forum to try and get some satisfaction !
Maybe the reason is that they envy canon glass, ergonomics or other things.....
I like Nikons green tint on the top screen when it's dark, canon has a bit yellowish(altough mine is blue).
I like that they have better sensors....
I think is should go to a Nikon forum and constantly talk about the inferior lenses.....
Keep on going about the extremely poor buffer on the d7100, and that there is no Wildlife camera in the current line up (other than the d4, which has only 16mpix on FF) for wildlife shooters that care about raw+fps+buffer ...... there is ?
Most likely the only response you will get is : But... I have superior DR![]()
hutjeflut said:Its funny how everyone keeps bashing this camera because the sensor is only a small improvement for stills.
However i think this gamera is the biggest overal jump in the history of the xxD series.
In general only the sensor improved slowly with each model and addes a few MP and a few small features.
But this time they not only slightly improved the sensor they also added other stuff thats quite welcome like
-wifi to upload to facebook flickr or clouds or even use the camera remotely over wifi with your tablet!
-a better 19 point all cross focus system from the 7D
-a touch screen
-faster live view focus
-in camera HDR which might be fun and easy
-better viewfinder coverage
-hybrid autofocus for video
-a stunning 7 fps rather then 5.3 which launched this camera into a budged sports camera
-decicated focus mode button that lets you choose focus mode while shooting and much more button layout optimisations life movie button.
so in reality this camera is a massive upgrade. and the few samples ive seen also show that the black levels and noise preformance is really visible when compared to the 7d which for its price now is the direct competitor.

The latest patent they have released (2013 for the newest variant, apparently they already had ones as far back as 2006 though) seem to make it clear they even have the designs to do it, or least largely so it appears, so they just need marketing to let the engineers start producing their DSLR sensor designs on Canon's more modern fabs or to build a new one instead of making the DSLR engineers have to work within the limitations of the very old 500nm Canon fab. But they have so far wanted to keep milking the old fab DSLR while all other other companies move on to new fabs for large sensors. (someone claimed they heard that Canon had shifted some of the newest P&S models to the older fab and speculated Canon had finally decided to use the 180nm fab for DSLRs now. Who knows. Just a rumor.)
I do have to say I do love the 5D3 video abilities though now that they have been unlocked by Magic Lantern. It's pretty astonishing. I don't think that really had anything to do with not getting better stills quality though (maybe costs it a touch in the MP count but then again it also got it to a very nice 6fps by staying lower, although I suppose they could've maybe fit in two digic since the 7D could fit two, but whatever)).
The new liveview AF for the 70D does sound it took quite a lot of resources up. It is very cool though. All the same if it was better sensor for IQ vs that I'd have takne the better sensor and then done this new AF later. For the 70D market perhaps the AF matters more. But in the end I think it's probably mostly just that marketing wanted them to keep milking the old 500nm line which probably meant there wasn't much the sensor engineers could really do.
