Shipping is free, but you have to pay for any pay-pal fees. (There's always a 3% transfer fee from pay-pal to my account but the other fees can be zero by using a "gift" option as I understand it.
PS: I have two of these lenses and they have different original contax front caps - one is a friction-fit and the other is a typical spring-loaded type. So if you're buying this lens please specify a preference.
Also I would be willing to trade this for a Canon 1D Mark IIn with a low shutter count, in excellent condition, and with 2 or 3 batteries + charger.
Here's the images:
The lens on the left is the one I'm selling but both are shown side by side here so that you can see the two different types of Contax original lens caps.
The one on the left is the typical plastic spring-loaded style cap. The one on the right is rubberized friction-fit type - maybe with a metal core - it's rubber all over but it doesn't bend like rubber.
