Nikon is a slave to Sony's sensors, which are quite nice this generation. But it's not like Nikon innovates in the sensor space, they just wrap a sensor they buy around their shell and software, which IMO is less inutitive than Canon.
If this were strictly the case, then Nikon's cameras should get identical performance to Sony's in the sensor department, if not actually be worse (why would Sony give competitors better sensors than their own, or even put them on an equal footing for that matter?).
But they don't seem to, even for full frame. For instance, the Nikon D600 kills the Sony Alpha 99 at high ISO performance, and though the dynamic range and color depth figures are similar, the Nikon still beats the Alpha slightly. They were released one day apart and are both full frame cameras.
No, I have to conclude that while Nikon may be making use of some of Sony's patents in terms of the sensor, and may be using Sony to fab the sensors, the design is still Nikon's.
Also one gearhead's rant about the technical details of a sensor doesn't necessarily reflect the opinions of everyone. 95% of the target market for the 70D has probably not heard about dynamic range and they don't care to.
This is absolutely true. How often have we heard the fallacy that "if you're pushing your shadows that much, then you didn't expose properly!" ? Since that is precisely how you make use of the full dynamic range of the camera, those who repeat that fallacy clearly have no idea what dynamic range really is, much less how to make use of what their camera supplies.
The 70D is better at dynamic range than the 7D. That's not so much because the raw dynamic range figures are any better, but because the sensor is clean in the deep shadows at base ISO, which isn't the case for the 7D's sensor (you get banding in the very deep shadows with the 7D).
So far I am quite happy with the camera. I am a casual user and taking hours to lift shadows and worry about the edges of the DR is just not something I care about. The 70D is about wrapping up a lot of features into a multipurpose package, and I think it pulls it off really well.
Any modern Canon camera is really an excellent package that is capable of taking outstanding photographs. These days, the camera is generally not going to be the limiting factor, particularly once you start talking about cameras with autofocus systems like what's in the 70D and 7D.
