I am 5'8" (OK a little altitude challenged compared to most of you).
I use a very old Vivitar "Professional Tripod" (their name for it, not mine) Model # 1321, equipped at present with a Monfretto 468 C2 ball head.
if I eextend the legs fully, the camera mounting platform is at eye level. i.e. I need to stand on my toes to see through the view finder.
Some have commented that this ball head is actually too small and I should be using a larger (i.e. also higher) one.
All of this is without extending the center column at all! You would need to be over 7 feet tall, or stand on a ladder to look through the lens with the column extended fully.
I guess the point is, you might want to look at some older used equipment (my vivitar is 30 years old) Maybe people were taller back then
p.s. don't ask about the weight. it does weigh quite a bit.
