http://www.ebay.com/itm/Helios-44-5...rKtARGslc%2BjAWjFbemg%3D&orig_cvip=true&rt=nc I picked this up reflexively as it was cheap and I just grabbed a Jupiter-9 and plan on grabbing the next nice, cheap Jupiter-3 that pops up. Feeling... Soviet... I guess. What adapter do I need to buy to use this lens on my newly purchased OM-D? I know it's "M39", but it's not LTM M39, it's SLR M39. Will an LTM M39 adapter work? thanks guys!
