Re: Help with tripod needed
If you mean the little peg sticking up next to the threaded screw to which the camera attaches ... these are common on budget tripods, there is a spring underneath so the peg pushes down when the screw is tightened. Can't see the point but lots of them have it! The little peg is usually metal, though.
I won't say I recommend this tripod as in my experience any tripod under £50 is a waste of money (being not rigid enough to do its job) but I don't think you'll have any problem fixing your camera to it.
If you're not living on the edge, you're wasting space
