Looking for advice. I currently use a nikon D7000 for everything. I would like to get another body and keep my D7000 as my backup. I was thinking about the D7100 but would rather have the high iso capabilities of the D600. I want to shoot in the studio and also shoot Weddings with it. Please let me know your thoughts. Oh, I forgot to mention that there are some reviews complaining about the D600 having spots on the sensor.
