Best lenses for filming edits

[*Goose*]

Just bought a Nikon D7100 primarily for photography but am looking to film and make some park edits. I have these lenses (not looking to buy a separate lens just for filming) - Nikon 20mm, 35-105mm, 50mm and 300mm. Which of these would be best for filming?

Why do people who spend 1500+ bucks on camera gear need to ask questions on a Canadian outdoor activity enthusiast board to questions that have been asked more often then me scoring in the basketball hoop on the other side of my room?

A lot of people use the Tamron 17-50 f2.8
