So... anyone here have any experience/knowledge of such devices???
I am aware that Manfrotto have a number of clamps products, but have no idea of their usefulness, and I have seen this clamp and ballhead product that looks cheerful but cheap http://www.bits.com.au/newbits/engine.asp?CatID=30&SubCatID=565&ManufID=&BSR=E&OS=P
Any other thoughts???
