Hello,

I am on the lookout for the 645 A 80-160 f4.5 lens for my Pentax 645N. I cannot afford much, so if you have one to sell, make me an offer and I will see if I can meet that.

Alternately, I have a Carl Zeiss Jena Sonnar 180mm f2.8 in MINT condition. Its a Pentacon 6 lens and can be adapted to a number of cameras with the right adapter. Going by fleabay prices and given the reputation of the Sonnar, I am willing to trade it with the 80-160 provided you pay for all the shipping costs involved (that is cost of you shipping to me and me shipping to you). I don't want any extra money.

The Sonnar is also separately on sale in the For sale section in case you are interested.

Thanks.

Avi
