The Nikon D7100 is a great camera, even though it's running about six years old now. It's still probably one of the better crop sensor cameras available on the market, even to this day, and especially at the current price point.  However, one of its limitations has always been with regards to aperture control while in Live View when  recording video.  

It’s pretty much been discussed among message boards and on YouTube now, you’re kind of out of luck with that. However, I discovered that live view recording and aperture controls was available when paired with the Tamron G2 series lenses.

More specifically the Tamron Di VC USD G2 lenses.  These lenses when mounted on the Nikon D7100 provide complete aperture control while in Live View mode when recording video.
