#7. "RE: Will the SanDisk 64GB SDXC Memory Card Ultra Class 10 UHS-I work on the Nikon D7100 ?" In response to In response to 6
I think that entire interviews shot from a single angle - from a single, unvarying position - are difficult to follow. Your D7100 can work perfectly well if you stop every 5 minutes or so to change the shooting angle, check the lighting, take sip of water, work a bit with the interview subject, and so on.
Interviews, for entertainment or research or family genealogy purposes, need shot planning. Interviews for security or law enforcement purposes do not.
