Buy & Sell Listing - Want to TradeTrading Panny 20mm f1.7 for Olympus 17mm f1.8 Location Texas Ships to CONUS Description Looking to trade my very good condition Panny 20mm f1.7 version 1 for an Olympus 17mm f1.8. Lens is great, but I need to sacrifice the picture quality for faster focusing. Shoot me a PM if interested. Will add some cash as well.
