This is a MINOLTA a-mount macro lens. I'm selling this a-mount lens, which I collected, because I don't use it often. The autofocus is smooth. There is some slight whitening on the rubber parts, but it's in good condition considering its age. There is no mold inside the lens. It comes with front and rear caps. This is an old lens, so please consider purchasing it with the understanding that it is non-refundable and non-returnable.
