What it shows is

i) This sensor is a Canon sensor

ii) Nothing has been lost in terms of IQ for the dual pixel AF function.

Yeah, I think that's important as many people were rightfully concerned that this dual pixel thing might compromise some aspects of IQ.

Re: Canon EOS 70D DxO Mark

I haven't to this point tried to understand the way DxOMark develops their data and data are important according to how they are measured and methods used.  However, though it does concern me that the DxO Mark data indicates Canon to be behind Sony and Nikon I have stuck with Canon due to the great results I get.  Also love Canon JPEG colors for landscape and street work.

I do use a Nikon D600 with Nikon AF-S 60mm f2.8 micro for copy work.  It stays on my tripod at all times since it is easy for me to do paintings/drawings copy work quickly as everything stays level.  I find the Nikon D600 to have great color saturation.  However, I use a Canon 6D for field work as well as portrait/figure photo work.  Get results I am happy with and I find Canon system easy to use.

On top of all that I just ordered a Canon 70D to replace my T4i as backup camera and BIF work.  I expect Canon will do what is needed over the years to stay competitive in the sensor area.  The new 70D sensor is just the beginning (IMHO) to future Canon mirrorless that will use all present and future Canon EF lenses.

I wonder if they lock threads because of vehement agreement.

Owning the 70D, I have no concern about IQ.  And my Nikon is now a backup cam.  As for DXO, they show no sign of changing their tune/view/way of doing things/ possible bias...and therefor I retain my skepticism about them.

Images and personal use and experience and many other sources outweigh one company: dxo.

Don't let them get to you.  I don't.

I think that (ii) is the real take-away that they put a pretty significant feature without breaking anything.  As far as we know (haven't really seen the banding detail yet).

Hi,

I'm one of the moderator of forum 10d-7d (and hopefully it includes the 70d).

I do not think much good about DxO ratings. Yesterday, I locked the thread about the DxO ratings. Too many people were at each other's throat and ready to strangle the people that disagreed with their point of view. Politeness and civility went out of the window.

Normally, I delete that comment and let the other people to keep on posting, but there were too many of them, and deleting each one of the "mean and nasty" comment would also deleted all the comments below.

There aren't many pictures to play with yet. My feeling is that banding is virtually eliminated in 70D.

I have processed RAW files from DPR.

In ACR I increased Exposure to +3, color NR 25, no sharpening, no luminance NR

70D shadow areas would be much easier to process compared to 60D or 5D2. I don't think DXO measurements reflects this.

I hope you are right.  I haven't downloaded the Beta ACR to look closely at this but IMO if the banding is gone the rest is pretty much a non issue.

What do I think?  I think it's pathetic that yet another Canon model failed to provide adequate torque at high rpms and lags behind in cornering ability.

I'm a Canon shooter. What I think is I'd like to see Canon catch-up to Nikon/Sony in terms of shadow noise which roughly equates with the DXO dynamic range measurement...it's been a few years since Canon fell behind on this. Having said that, the dual-pixel technology is impressive and is most likely leading the way to a future of dumping the dedicated auto-focus phase detection system and allowing phase detection focusing pretty much anywhere in the frame.

Re: Canon EOS 70D DxO Mark

I don't think there is much to catch up, as Nikon don't provide intact true raw some processing is appliyed whereas Canon is just demosaicing true raw.

Comparaison is a bit old but still in todays philosophy of the two houses :

http://www.astrosurf.com/buil/cameras.htm

By the way i could only watch raw files from internet here and there and i think the image quality is very promising. Of course you have to fine tweak but there is a progress undeniably, i positively surprised. Waiting for raw from real life if someone can post some...

In that case what could that mean for the future of the International anti-banding and read out noise Association?

Could you please provide some evidence to support that assertion?

That is just a contents page. I think it comes close to intellectual dishonesty when people include links which don't directly support what they are saying. I guess the idea is that most people don't bother to follow the link, and think 'oh yes, he has a supporting link, he must be right'. In the case of the astrosurf site, all I can remember in terms of 'raw processing' is Nikon's well documented long exposure processing. There is no implication that 'some processing' is applied to all raws, nor for that matter that Canon doesn't apply any. In fact, we know that Canon does indeed apply NR to raws in some of its latest cameras, DxOmark found pixel noise correlation which provides direct evidence of noise smoothing.

BTW, are you the same person as all the other PIX personas? Not objecting, just wondering who I'm talking to.
