New looking Tamron-F 28mm f/2.8 in Nikon mount, No. 742206. Dusty but clean glass, no scratches or other marks. Smoothly operating focus and clean, smooth aperture blades. Is it AI'd? Sorry, I wouldn't know, I'm not a Nikon guy. This was in a box with some other stuff. Has a rear lens cap but no front; I'll figure out something to protect it for shipping (takes a 62mm filter or cap.) How about $30, plus postage? I take Paypal or USPS money orders (United States Postal Service ONLY!) and ship quickly. Thanks!
