1. That's an opinion, not fact, and what I said is not false information, it's correct information. It's just not the way you choose to go about shooting. Your over expose, correct in post crap of a response, will never work for concerts, especially night ones, due to the fact that concerts use powerful and harsh spot an accent lights.
Second, you can blatantly see noise in an image at less than 1mp, on a camera less than the d700. Don't believe me, go try it on your d90 or d40.
As said before, nothing I said was false. Not one single thing. It just helps you be a narcissist to proclaim that.
Not necessarily. The information I have gotten was based off credible reviews and speaking to people who own the camera. I understand your comment on ETTR and spot lights etc.Fortunately, I haven't run across that issue. Not even in night clubs with spot lights and strobe lights..
btw - i am not saying over expose to the point of blowing everything. ETTR works pretty well.
In any event, happy shooting, typing, spreading your opinion or whatever makes you sleep better.
OP- if you plan on doing this seriously with your camera, I suggest upgrading glass and learning how to read your histogram or at least how to turn on the "blinkies" for your highlights. People make the misconception that their shot sucks because of their gear when in all actuality- it's usually user error. It will be a long time before you see any real limitations in image quality from your camera. By the time you truthfully see its limitations or outgrow it, you won't be asking questions like this.
Listen, I'm sorry this got off to a bad start. You seem to be pretty knowledgeable, and I wasn't insulting your intelligence. When you made the first comment, I thought you were implying that it had been the first time you had heard that the 5100 and 7000 is the same sensor, not that shooting at 3200ISO wouldn't suffice.
Believe it or not, the results from this camera at 3200ISO aren't terrible. Really it does pretty well all the way up to 6400ISO... once you get into the Boost ISO's is when it gets terribly bad. 1600ISO is pretty clear, and it's not until you get to 2200ISO that things start to look a little bit grainy. When I say "a little bit grainy," I don't mean that it's so awful you can't keep it. I'm saying, in my personal opinion, it's not something that I would want to keep. His taste might be different. Who knows.
I just know I certainly wouldn't be giving photos shot at 3200ISO on my camera and many others to anyone. The only time I would ever keep them, is if I was just wanting to have them as snaps for myself.
