Hi, there's a 110mm for sale on Ebay: http://www.ebay.de/itm/ROLLEI-F2-110...item2c615c18b9
I've seen one or two more there in the past few months:
I've also seen one or two for sale in the classifieds section here. Don't give up!
I'm intersted on your Leica 180mm f/2.8 Elmarit-R II.
Can you make it 150 with shipping to Portugal?
