My father-in-law, who passed away in 2010, was an avid photographer. He, I am sure, drove the local pros crazy because he worked for practically nothing as the photographer for theater groups, choirs, corporate executive portraits etc. I have his old Leica and a couple of lenses; sister-in-law has the newer Leica gear. I recently borrowed back (from my brother-in-law) a couple of his Hassleblad lenses and will do a few trials of those connected to my K-1 via H-to-K645-to-K adapters. First impressions, ho hum. But then there is his Nikon gear…
I thought my sister-in-law also had all the Nikon items. But my mother-in-law recently passed away, we have been cleaning out all the closets, distributing family memorabilia, and getting rid of excess stuff. I found boxes on Nikon gear. F3 body and motor drive, multiple flash guns, filter sets, etc. The lenses are mostly early 1970 acquisitions: 20/4.0, 28/2.0, 55/2.8, 85/2.0, 105/1.8. Ho hum. Hopefully I can find a home for these. What I think is the prize in this collection is a Nikon ED AF Nikkor 180/2.8 . I have an inexpensive adapter to K-mount, with a lens insert to allow for infinity focus. I have on order an adapter which does not have any glass, so no image degradation but no infinity focus. I look forward to playing with this a bit! So, to the question. Is it feasible to permanently replace the Nikon mount with a K-mount? Maintaining infinity focus without added lens element(s)? stan -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
