So I bought a Vivitar 100mm/2.8 Macro from eBay ridiculously cheap - only it seems some idiot got a shitty lens hood either stuck or possibly even glued to the filter thread. Any good way to get rid of it?
Pic related. The whole three-layered stack of shit is actually the offending part. The shiny (fouth from the top) black ring below it is the top of the lens' own, integrated, extendable lens hood.
