Replying to Video tips

So i do a lot of photography and want to get more into filming. Are there any tips you guys have as far as settings go and what angles are best for follow cam shots?

My setup right now is:
Canon t3i
50mm 1.8
Tamron 17-50mm
Rokinon 8mm fisheye

As for mounts go:
Opteka x grip but the aluminum one not the shitty plastic haha.
And just a regular tripod.

So another question i have is. What mounts should i use and what lens? I was thinking the tamron 17-50 and the opteka and maybe a lil fisheye. I think using the 50mm would be extremly hard to film with.

Im going to be fillming mainly follow cams with some rail shots from a side view.

I look forward to hearing what advice you guys have! Thanks!
