Hi guys, I'm looking for suggestion from someone experienced in shooting videos with DSLRs. I got the new Nikon d90 and I'm starting to take videos. I'm thinking about upgrading my tripod with something useful for still photography and video as well. Today I have a Manfrotto 190XB + 486RC2 ball head. I think the biggest problem is the head. Fluid heads usually don't have the portrait position so they are not good for classic photography. On the other hand, classic 3D head are not fluid and then not useful for videos...... any suggestion?
