I presently shoot with a D7000 and would like o make the plunge to full frame. I really like how the D7000 has both front and back dials for the shutter speed and aperture, and like that I don't have to dig to change the ISO or set my white balance. I have no idea which full frame to get and am open to suggestions. I shoot primarily newborns in a relatively small space, and use both natural light and of camera flash. Thanks you!
