Whats a fair price in great condition OM 50mm 1.4 lens? I see them used on BH photo for $129.95 they include a warranty too, but wonder if its overpriced? I like to venture into the OM lenses just for fun a bit if I don't like it like after a year or so like to re-sell it. Would have to get an adapter too, the MF-2 OM Lens Adapter is also not too cheap. thanks for advice. Tried a search for OM adapter couldn't really find much.
