...BUT IF CANON ARE GOING TO PUT THAT LIGHT LOSING, DETAIL TRASHING DUAL PIXEL SENSOR in the 7D then it is time to buy a Nikon....

How is the dual pixel sensor loosing any light or trashing detail. From what I have read the two pixels are treated as one for the final image so the amount of light gathered and the detail that the sensor is capable of will be the same as if the pixels were one to begin with. Have you read differently?

I do not see how it is possible to split something into two and not lose a tiny bit? Even a fraction over those pixels which are dual = alot of light loss overall. On top of that Canon increased the pixel count on the 70D. Having seen shots I will not buy into it, at f8 where cameras and lenses should be tack sharp the detail is mushy. If you need video and AF then fine, go with the trade off but if my stills will lose out then I will skip Canon APS-c thankyou very much.

You understand that the 70D Dual Pixel CMOS AF is only for Video (even at it's highest resolution, it is much lower than the sensor resolution) and live view. You have lost nothing with this feature.

Well.. that may be true that it was developed primarily for video but the dual pixel focus will work for stills just as effectively if you are shooting live view.

Interesting place to have edited my statement. :)

The dual pixels will be less efficient at the edges. There will be some additional light loss. It's up to Canon to lower noise accordingly so they can show an improvement in IQ using fewer photons. We will see how they manage.

What I'd like to see is some revolutionary new feature that DOES effect photo quality.

Of course every single review on the 70D so far has said that the sensor performance is at least the equal of the 7D, and perhaps a bit better. :rolleyes:

A lot has happened with DSLR manufacturers in 4 years. If the new sensor is not discernibly different, then isn't that a failure? Rather then saying thing like "at least equal" or "perhaps a bit better" they should be saying things like "a major improvement".

I don't disagree, but when you start talking to those actually use both Canon and Nikon/Sony, they usually don't find that much real world difference between them. Arguments between the Canon and Exmor camps seem to focus more on charts / tests / DXOMark scores, not on which cameras consistently capture better images.

As for the 70D, it seems the Dual Pixel AF is the "major improvement." An extra stop of DR or less high ISO noise would have been great, but it's not quite a "LIGHT LOSING, DETAIL TRASHING DUAL PIXEL SENSOR."

Depends what you shoot and how much control you have over the lighting.

Most landscape photographers I know, at least, have completely dumped Canon, or only use Canon bodies for non-landscape purposes.

Canon still loses in the ability to lift shadows in post. If you don't do much of that, you won't notice the difference. Canon still has better color, IMO.

I did mention several other things I didn't want, apart from video. Does anyone really want a flappy screen on the mkII?

I like the flippy screen. I have been surprised how often I miss it on the 5dIII

You know that dual pixel is only for focusing!?!?!? handy do have for video, live view focus is MUCH quicker.

F8 on a crop body is beginning to suffer from pin hole effect.

Yes, that's why I called it by its name: Dual Pixel CMOS AF.

But I'm interested to know what you mean by: "F8 on a crop body is beginning to suffer from pin hole effect." Can you please explain and document that statement? Because it sounds like nonsense.

I'm guessing that what they meant to say is diffraction. The pin hole effect, DOF approaching infinity as the aperture gets smaller, many times is desirable but diffraction which is totally different is not.
