Sony A mount to Nikon lens adapter?

I have a sony a33 and i was wondering if an adapter was available that would change an a mount into a nikon mount. If you know where to buy 1 please send me a link.

There are problems here. If you can find such a mount, and this is in many cases not all, the auto features of the lens won't work because there's no communication between camera and lens.
Second, it will change the f/stop and perhaps focal lengths of the lens and clear, crisp focus may not be possible.

The best lenses for your camera are the ones made specifically for it but hey, good luck in your hunt.

To my knowledge, no such adapter is currently on the market. Even if it were, it's not worth the trouble. If you think Sony's lenses aren't good enough, take a look at the CarlZeiss line or consider moving to the Nikon platform altogether. It is rarely, if ever, worth the hassle to try adapting a lens to a mount for which it was never intended.

Mmm yup you kinda are in trouble because allot of controls nikon offers are ON THE LENS. Not easy to bridge a brand that way in the best case you have a Full Manual lens in the worst well you have a lens that is stuck in its widest aperture.
