I have both of these lenses that are not seeing the use they should. The Panny 20mm is about a month old now, so it's as nice as you will find. The Oly 12mm, that's about 6 months old, has no hood, was used just a few times and again, as nice as you will want to find. Panasonic 20mm SOLD...... Thanks Allan !!!! Olympus 12mm SOLD........ Thanks Hank !!!! Both include shipping to US addresses and Paypal fees. If international shipping is needed, the additional cost of shipping must be added. If you can send the funds as a Paypal Gift, you can deduct the 3% fees I would have to pay. If interested, please PM. Thanks !!!
