Exactly what it says on the tin.... NIKON NIKKOR AF f1.8 D/G prime lens. I am new, working on a budget to build my way up. if anyone can recommend anything similar and as good, be my guest. primary use is to have a go with it to shoot skateboarding/snowboarding. I here it is quite the handy lens and decent reviews for what it is worth. Cheers, gowge
