I am selling a mint condition 240mm APO Nikkor lens in barrel. The glass is pristine, and the aperture ring moves smoothly. The lens covers 4x5 at infinity or larger formats in the macro range (see below). I originally bought this lens to do macro work but then picked up a lens in a shutter. At the link below, you will see several beautiful 5x7 macro photos by Ken Lee taken with 240mm and 360mm APO Nikkor Process lenses (among others). http://www.largeformatphotography.info/forum/showthread.php?p=513610#post513610 $120 shipped in the continental US. You can reach me at anthony dot karnezis at gmail. Thanks for looking.
