Nikon Series E 50mm F1.8 AI-S order

Product Name: Nikon Series E 50mm F1.8 AI-S order
This is a Nikon Series E 50mm F1.8 lens for Nikon film SLR's, completely manual aperture and focus. Please note this lens doesn't have the “rabbit-ears”, so metering won't work with the film SLR's that meter using that system order. I used this lens on my Nikon F3 without issue (and with working metering) up until I upgraded to a 50mm F1.4. Focus and aperture ring turn as they should. I priced this lower than “Excellent” rated copies on KEH due to the slight dust. Lens definitely has dust on the inner elements, but image quality was not affected from what I can see. Please see attached photos I've taken using that lens.
