Hi,
I sold my 645Z, but I have the following lenses that I would like to sell as I've decided to move to a different system:
1) Pentax DA645 28-45 f/4.5
2) Pentax DFA645 55 f/2.8
3) Pentax DFA645 90 f/2.8
4) Pentax A645 35 f/3.5
5) Pentax FA645 80-160 f/4.5
6) Pentax FA645 300 f/5.6
I bought the 28-45, 55, and 90 new (from B&H), whereas the 35, 80-160, and 300 I bought used on e-bay. All lenses were bought in early 2015. Let me know if you're interested, would like to know more, etc. My email address is jbuchow at hotmail dot com.
