Bought this lens with a Contax N1 camera. Was used very little & still in absolutely MINT condition with original hood / pouch / box / packaging. This lens can be MODIFIED for use with Nikon / Canon, etc... This is a very sharp lens, being advertised these days for all kinds of prices ($604 up to more than $1000...). I presently have no use for the lens and am selling this for $580. If interested, call 561-523-0294
