Cosina Voigtlander Nokton 50mm f/1.5 Leica Thread Mount LTM ASPH
$450 shipped and PP'd to CONUS. Worldwide shipping available, but only USPS Express Mail with tracking and insurance. Usually runs around $50-55.
This is a fantastic lens.
It's in fantastic condition. There are some very small wear spots on the body and lens cap, but the glass is beautiful. Aperture and focus work perfectly.
I also have a Rainbow Imaging M43/ Leica Thread Mount adapter I will throw in for $10. It's essentially new and unused.
Comes with box and manual.
Wide-open on my NEX-6 (missed focus, but render and bokeh are lovely)
