Pentax 6x7 400MM f/4 lens in good condition. Optics are great with no marks inside or out. Understand this will also work on the 6x7II. Has some small marks or scratches on body, and 1 small ding in the hood, about where the Japan on my photo is, but it still functions fine. Filter ring is OK. No front or rear caps. This is a very heavy lens, weighs almost 6 lbs and measures a bit over 12 inches long and is 5 inches round. Cost new was about 4000.00 and the new replacement is almost 7000.00. Sold my 6x7 and have no use for it now. Have references available, just email me. Also have a few high resolution pictures available, also just email me.. May do a part trade on this lens, email me, what you have in mind. Pls excuse the few pieces of dust on the glass. Also asking 835.00.
