I just got a Bogen/Manfrotto 718B for my longer hikes. I noticed something silly when I came home. When the head is in it's basic landscape position, it is not straight! It is noticeably tilted to the right (over the 0 degrees it should be, if we consider portrait shots to be -90 degrees).
Do you find this acceptable? To me it feels really stupid. Or. Maybe I am stupid? Anyways, I think I'll take it back and see if they're all like that.
