don´t worry, nobody is going to question the 5dmkIII´s noise superiority. i don´t think it´s 1 stop either, but this is totally subjective...
but these days, it´s such a small difference, which is really easily erasable in post.
noise is not a problem anymore with new tools and technologies.
It's not subjective, there are tools that can measure noise and give ideas on how well one works compared to another. 1 stop is not a small difference, again, given really good NR skills, you can remove 1 stop of noise while maintaining a majority of detail, but you have to use the correct tools and accommodate for the camera you have and its characteristics. Most folks don't have that skill or tools, thus making 1 stop a big deal. 1 stop equates to a 1/500th shutter speed vs 1/1000th, if you are shooting action, for example. 1 stop isn't just about the noise, it is about what else on the exposure triangle you now can adjust.
If you remove noise, you remove detail because even the best of tools or techniques cannot distinguish between pixels that represent detail and pixels that are noise. You keep pushing how your 70D is very, very close to the FF, but it really isn't, not technically. It's good enough for you sure, and that is fine, especially photos on a web forum (which print out to the size of a wallet photo), but actually try to produce large prints for clients, or try to enter a contest where they are sticklers for IQ, it won't cut it in many cases. Of course your answer there is, who looks at photos at that detail to see the noise? Any time you crop a photo then try to print it, or submit to an agency for review, and there you will learn the answer.
Noise is as much an issue as it was before? The only thing that has finally changed to help NR is that Canon seems to have gradually "fixed" the banding and pattern issues with noise. The more random evenly dispersed the noise is, the easier it is to work on. That is why noise isn't quite the issue now as it once was, but the amount of noise is still there lurking in the shadows for some shooters, like landscape shooters or high DR shooters.
Let's just put it this way. The 7D2/70D will be within 1/3 to 1/2 stop of the 5D2 at ISO 6400, and that is a very good thing. Better would be if they were closer to the 1D4, but perhaps the next iteration.
Of course what do I know? Maybe I am just lacking in my crop processing and noise reduction. A profound quote from Watto to Qui-Gon comes to mind right about now.
