This is an Olympus Zuiko 55mm f1.2 Fast Lens! Lens is clean, smooth, has both caps. I am asking $225 shipped insured. Payment by Paypal, Money Order, or Personal Check (I will wait 7 to 10 days until the personal check clears). I have reduced the price to sell to an astrophotographer (or future one), rather than putting this on an auction site. This is a great lens for fast normal field work.
