I have three really nice LF lenses for trade, a Mamiya 645 300mm f5.6 lens is worth about $250 the 2.8 version is worth about $1K, I will happily trade the three lenses for a 300mm f2.8 or one of the lenses for a 300mm f5.6, a Mamiya 500mm f5.6 is worth around $800 and will trade all three lenses for one of these lenses if in EX+ condition plus a little cash from you. We can work out the details if you have one of these two lenses I am interested in, PM or email me so we can discuss it.
