Has Nikon awoken the slumbering beast that is Canon Inc? IDK, but I remember vividly when AMD Anthlon 64 was head and shoulders above Intel Pent.4 in performance... Then Intel released Conroe and AMD was like O_o O_o O_o....

?????????????
Nikon have 4 different partners, Canon none except Fujitsu who are mounting/assemble Canon sensors
Two of them are in the front regarding mobile phones=Sony , Aptina
Sony , Toshiba in the top of APS and 24x36mm sensors

I guess the point flew right over.

If its totaly clean @ iso3200 i will be very happy!
haha. because 1dx and 6d produce noiseless pictures at 3200, right.

I don't think that the 70D will be far better than the 60D. The better Chiptechnology will loose a lot of it's capabilities to the fact that the resolution is higher and the pixels are even smaller because the PhaseDetection-AF is next to the Lightsensor. On the papers from Canon the Pixels are about 50% of the former ones... I think we can be lucky if the 70D has a little bit more IQ than the 60D or 700D.
The 'PhaseDetection-AF' and the 'Lightsensor' are one and the same thing in the dual pixel AF. Under each microlens, instead on one 'Lightsensor', there are two. For AF, the two are read individually to detect phase. For making an image, the two are combined to recreate what a normal sized 'Lightsensor' under the microlens would see.

Yup, They almost do ;) But i don't think canon can make FF quality in a 1.6 Crop xD we will see :P
It's the image of the image.

Not sure if it has been posted before, but here is a link to a polish site with test shots ranging from ISO 100-25600.

Canon EOS 70D + EF 50mm f/1.2L USM, JPEG with in-camera noisereduction off and lowest sharpening.

doesnt say much, because we dont have any comparison versus, f.e., 7D/60D etc.

and noise results get much worse when shooting in poorly lit rooms/avenues.

They shot this with the 50L @f8 and it's still soft which makes me believe these jpeg shots might have (some) noise reduction applied?

Anyway, the 60d vs 70d comparison doesn't get my hopes up for a significant performance, the 70d looks about the same as the 60d plus a minor boost in resolution:

* iso800: http://pliki.optyczne.pl/C60D/IMG_3442.JPG vs. http://pliki.optyczne.pl/C70D/przyk1/C70D_f14.JPG
* iso6400: http://pliki.optyczne.pl/C60D/IMG_3464.JPG vs. http://pliki.optyczne.pl/C70D/przyk1/C70D_f17.JPG

As always, this is really not saying anything until a final 70d raw converter is out which usually takes a while because ACR is only released every couple of months.

This is like one of those awful oil company promo pics of a driller in the artic clapping a polar bear to show they care.

I'm not sure that giving a polar bear the clap is showing how someone cares   ;D

I think that would be the last time they tried that with a polar bear.

For what i have seen the 70D example pictures looks nice. But it's hard to compare a picture from a 70d with another from a 60d. I need the same object shoot with both DSLRs with same lens to compare.

Are there any example pictures from 70d vs 60d on full size?
It's the image of the image.

Hi there!
I have checked and compared pictures of 60D, 70D and 7D at 6400 ISO from the polish site and I've noticed the following:
1. In the exif, I've noticed a difference in exposure: for 60D and 7D time was 1/3200 and no exposure compensation, and for the 70D it was 1/2000 and +1EV compensation. Not really the same in my opinion but let's say it will do.
2. If you check the brushes on the right side of the images, you'll see that for 60D and 7D the metal part is blown away (no details or very little), but the 70D retains all detail. In case they didn't change the lights orientation ( and if you check the reflection on the bottles they seems to be the same), that means some more dynamic range for the 70D.
BUT, in the shadows it seems to me to be more chroma noise, so maybe they are using HTP.
What do you think?

Regarding #2, the lighting in the 70D shot is different. I had the same thought, that it looked like the 70D had FAR more DR than the 60D or any other 18mp APS-C canon camera. Upon closer inspection, there are just harsher highlights reflecting off all of those key surfaces than in the 70D shot. Kind of a bummer, that the test scene can change like that...really messes with the ability to compare shots, or for that matter (as you noted), photograph with the same exact exposure settings.

Try the optyczne.pl comparison with the 100D.
It seems that lightning and exposure are much more similar vs the other samples:


After comparing the ISO-1600 samples, the 70D doesn't seem to be any cleaner than the 100D.
At ISO-12800, though, the 70D is slightly cleaner.

And comparing the 6D samples (scroll down the page), I still see the same difference of 1.5-2 ISO stops
as between the 6D and the 18mp models.

So, overall, the 70D doesn't seem to be an improvement over the 18mp sensors in terms of ISO.
ISOs 6400+ seem to be slightly cleaner - but that's about it.

Oh, well. We can only hope that the 7DII will bring some real improvements.

Probably the 70d has an added *real* analog iso6400 mode, while on the current 18mp sensor iso3200 is the highest setting and everything above is pushed *digitally* which you can also do in raw post w/ better results.
