So I am a concert photographer, and I recently upgraded from a D80 to the D7100. I first used it for a show twice this week, and both times it was extremely lagged. For instance, when I take a photo, it takes up to a full minute for it to be displayed on the LCD, especially when doing it in bursts. I'm not sure if I have a defective model or if there is something up with the software. I have two memory cards in, but do not have it set on the backup mode.
Help! I have another show at the end of the weekend and need this to be fixed!
