I have a Sigma 30mm f2.8 in like new condition, which I've listed on Amazon and thought I'd put here as well in case anyone's interested, it's priced at 169.99 there but I'd let it go here for $160. Ideally I'd love to switch for an Olympus 45mm f1.8 and would be willing to pay some on top, so if you have any desire to trade, PM me an offer! Also would be willing to consider a trade for a Panasonic 20mm, Sigma 60mm f2.8 or possibly a Sigma 19mm. I love the 30mm but it's seriously underused for me. When I say like new I mean the lens is spotless, with all accessories and the original box, only mark anywhere is very light scuffing on one part of the lens hood. Price: $160 PayPal +3% buyer adds. Location: US. Shipping: US. Shipping fee: free. Or trade + $$ for Olympus 45mm in good condition. Thanks for looking! I'm Agent Lossing on Amazon and something like that on eBay as well if you're curious.
