I think the most I'll use a tilt head for, as zac08 said, portrait & landscape orientation. Otherwise, a ballhead on a monopod is just too flimsy to adjust. For me, I just attach a quick release adaptor to my monopod (when I use it in those super rare times) for easy mount/dismount... =)
try tilting the monopod when you are shooting something thats half your height and 5m away from you.
i am not saying we are going to shoot that every single day, every simgle time. but with that ball head, you can set it in that angle, while still maintaining your monopod upright for maximum support and stability. it takes a genius to use a monopod at 45% tilt.
thats why up till now, i kept my ballhead on my monopod. for such rare occasions. otherwise its always tightened at the "straight up" position.
I use a old tripod ballhead from a PPCP V2 tripod..... with QR plate, much eaiser to separate lens (EF 70-200mm f4 IS) from monopod. Also, by loosening the ballhead, I could position the monopod into more type of angles then normally possible.
Just to check that this head is only to adjust orientation from landscape to portrait only right? Can it be used to adjust up/down angle? If I don't need portrait shooting, do i still need a head or just attach the camera directly to the monopod?
Sorry for the questions as I have never use a monopod before. Thanks.
