Negative. At least with the 322RC2, you can go a few degrees beyond portrait. If you have the plate mounted at the end of the handle (not the way it comes by default but just requires a screwdriver), it will go portrait in both directions. The default setup, which is what I use, will do portrait on the right side only (I don't know why it would matter, but just throwing this out there just in case). It's the only head I've used, but I like it and have no reason to upgrade to something more expensive.
I'm far from an expert but I've been comparing modern tripods to my ancient tripod. I think one of the biggest changes and something I want is the ball head adjustment... Especially with a pistol grip. You just pull the trigger and it unlocks the head and you can swivel the camera in any direction. Then you just let go of the trigger and it locks in place.
Compared to my tripod where you have to loosen like 15 knobs just to tilt the thing. :lmao:
I am under the impression that pan and tilt has it's benefits as well. You can't tilt the camera to portrait orientation on a ball head I believe.
