Isco Gottingen Isconar 100mm f/4 manual aperture lens, K mount modified Marketplace Listing

Item for Sale
Isco Gottingen Isconar 100mm f/4 manual aperture lens, K mount modified

Asking Price
65.00 USD

Item Location
Pennsylvania (United States)

Item Description
Up for sale is an interesting m42 mount lens, the Isco Gottingen Isconar 100mm f/4, that I've modded to full time K mount.

This lens normally will not be usable on a Pentax K mount SLR, since the base is so narrow that it allows stray light into the body of the camera with a standard Pentax m42 to K adapter. What I've done with this one is to attach it to a flat metal adapter that covers the entire mount and adjust the infinity focus so it is correct when using it with this adapter.

The lens istself is pretty interesting, Isco is a sub-brand of Schneider Kreuznach, and thi slens definitely has a European feel to it, with a little bit of a Meyer bubble-style bokeh to it. It has a 10 bladed fully manual circular aperture, so highlights stay consistently round across apertures.

Overall condition is excellent with glass free of scratches/haze/fungus, great mechanics (I relubed the helical), and light wear. I have an original branded cap somewhere that I will make sure to attach before sending it out as well.
