The design dates back to M42 days. My first SLR was a Honeywell Pentax H2, bought used in 1966. I also picked up a booklet on the Pentax system, and just dreamed of having this lens. I still think from time to time of getting one, but they are for sale rarely.
Are you shooting it on a DSLR? Let us know how it does. Also, how to you find focusing it at F8? Joe -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
