This is very much a noob post so I'd greatly appreciate any help!

Basically I've bought my first proper tripod (manfrotto 055xprob) and video head (Benro S8), but I think I've overlooked something pretty major.

I've got the flat mount tripod/head and so basically I'm just realising now that I can't quickly level the head, as I did with a setup I was previously using (which I think had a bowl mount).

Is there any way of quickly levelling my head with the flat mount stuff now I've bought it or have I shot myself in the foot?

If there isn't anything I can do to adapt the flat mount head to level quickly (I doubt there's an adapter or anything) then do you have any tips on how to level the whole setup in a shoot with more speed?

I feel very silly after doing so much research and overlooking such a simple thing.

Made for 75mm fluid heads. Allow to mount many other stuff.

Price: Less than $90 shipped
