Looking to upgrade my tripod along with the head this summer and wanting to get some input on positives/negatives of a ball head vs a pan/tilt head. I mainly use my tripod for landscape & astrophotography with a D750 + lenses so wondering which type of head would be more sturdy along with ease of use? I currently use a pan/tilt head on a Slik tripod but have a ball head on joby gorillapod. The Slik is what I use for landscape/astro while the joby is used in hunting. My main concern would be can a ball head be sturdy enough for long exposures. Looking to upgrade to a Manfrotto system in the $250-400 range for tripod & head.
