I'm at the point where I am strongly considering upgrading from my D3100 to the D7000. I have learned alot from my D3100 and have been operating exclusively in full manual for the past 2 years. I have grown tired of the low light performance, and specifically the large gap from 800 ISO to 1600 ISO, where picture quality goes from good to atrocious.
Playing with a D7000 and talking to other owners, it sounds like there is no way to set a shortut to change ISO? When I am in full manual on my D3100, the thumbwheel is of course shutter speed, the exposure compensation button is depressed to change aperture, and I use the function button with my left thumb to access ISO and use the thumbwheel to adjust. I love this set up because I do not have to pull my face away from the eyepiece.
So is there a similar way to set up the D7000? Granted, I will now have a dedicated aperture wheel - very exciting! But the ISO button on the back means I have to shift hand positions. But, I'm told you have to use the up/down pad to change ISO??
Please tell me these other owners just don't know better. There has got to be a way to change ISO on the fly!?
