Comments about Slik Slik SBH-120 Ball Head, for compact Point-and-shoot Digital and film cameras:
Ballhead will not lock when the camera is at an angle IE:(on the Gorilla Pod) for which it is sold with. It's just not going to work with the Gorilla Pod when the camera is hanging off the side of a fence. BTW I only have a 40D which isn't that heavy and no matter what lens I use the head will not stay locked in place.
