This lens was supplied directly to Sam Haskins by Pentax UK when the 67 system came out in the 70s. But Sam was never an architectural photographer and tended to shoot primarily with standard or short telephoto primes. This lens was not used more than a handful of times. It is essentially in perfect condition.

The optics are clear, all three mechanisms are smooth (aperture, shift and focus) I cannot see any flaws with this lens apart from the one very slight small scratch on the barrel which is barely visible.

The serial number is: 8439605. 

Comes with the original case which is still in very good condition with a few external scuff marks.

The lens will be supplied with a letter from The Sam Haskins Estate certifying that the only previous owner was Sam Haskins.

For those of you who are unfamiliar with Sam Haskins' work see the following links. Sam was a Pentax sponsored photographer who produced roughly 15 calendars for Pentax over 30+ years.
