I figured out how I was able to get the max upward tilt out of the 410 head: Raise the center column. (Although this only makes the whole rig more unstable).
Otherwise (on my tripod anyhow) the controls can bump against the top of the tripod. The 410 head allows you to tilt 30 degrees up. I'll experiment with turning the camera around. The head turns down 90 degrees.
According to the specs, a
410 head will support up to 5 kg or 11.1 pounds, but a
5x7 Sinar P weighs 8.2 kg, or 18 pounds.
So I'm over-loading it by... 75%. Oops :rolleyes:
