don't know about the 7200, but i been saying the 7100 is scared of the dark for about a year and a half now. Depending on the light (as you mentioned exposure) i can push it up to about 1600 usually with a usable image and no major noise reduction.. Really like to stay under a thousand though. I would like to suggest that there is a a "fixed point" of actual usable iso. But there really isn't, all depends on the scene. Sometimes you have to or want to under expose. Higher iso's go soft and the shadow recovery can become problem some.. Not to say they can't be done, depends.. Keep in mind the 750 is full frame and twice the price. Two totally different levels.Your welcome
1. You're implying that I don't know how to read a histogram
And 2. Not every scene is evenly balanced where one exposure will cover all the tonal values. For example, photographing osprey I need to spot meter their white feathers otherwise I'd get a bunch of blown out highlights. On my 750 I can expose for the highlights and pull out shadow detail no problem even at iso1600 or higher without introducing a ton of noise. Even at base ISO on this camera I have to nail the exposure because trying to bring out shadow detail ends up looking terrible. Maybe I should just ask the ospreys to hold still while I bracket a few frames for HDR?
I just upgraded from a D90 to a D7200 and the difference in low light performance is night and day. With the D90 anything over 800 looks like crap. With the 7200, I can comfortably shoot at 6400. That's 3 full stops. I did consider the D750 but I like the extra reach that I'm getting with a DX camera when using telephoto lenses.
