This 3rd party lens (like all of them) makes lenses specifically to fit Nikon, Canon, Pentax, Minolta, etc. camera body mounts. Each has a style mount that is unique. You can not simply mount a lens made for use on a Nikon body on a Sony body.
In order to use this lens, it MUST be the model designed for use on a Sony camera. Functionally, the lens will be nearly identical on any camera it is designed to fit, only the mount (the portion that actually mates to the camera body) differs from one lens to the other.
If you bought this lens without specifying it needs to be used with a Sony camera body (and it is for a different camera) it will NOT mount. Determine if the lens is indeed designed for a Sony camera body. You may find additional letters & numbers on the lens that can help you determine which camera body brand it fits by plugging the number into Google for a search. Additionally, the Quantaray brand is / was a
Ritz Camera "house" brand. You could probably bring it to one of their stores and learn all you need to know about the lens there.
Good luck!
