FS DFA 100 macro

I am restarting this listing at the knockdown price. A very nice lens in very good condition, this is the best Pentax lens of my collection and strangely the last to go. Box is tatty but all bits and pieces present, including the soft pouch in very good condition, hood, papers, caps (I don't think rear cap is original). Not sure the purpose of the 'clamp' switch, it seems to do very little and does not seem to be a focus lock mechanism, but the lens works perfectly.

Looking for £265 to include RM signed for service. Payment via paypal with buyer paying fees.
