This lens came to me with a mint F3, and as I already own a 50/1.4 the 1.2 has to go.
The 50/1.2 is quite soft wide open, very sharp at f/2, and with some interesting bokeh.
This is the Ai version, not the current Ai-s lens. Only difference as far as I can tell is the 's'-part and 7 aperture blades instead of 9.
The glass is very clean, also the inner elements, no dust or haze or anything. Aperture is snappy and clean. Focus is smooth. Some minor cosmetic marks on the housing and also on the hood (HS-12). With front and rear caps (original Nikon).
Price: 250 Euros, including Paypal and shipping within Europe. WW shipping possible, ask me for cost. Bank transfer is also fine.
I have excellent feedback on ebay under 'sanderpander' and a credible posting history on this site.
