Fisheye question

I have an Opteka 37mm 0.3X HD Ultra Fisheye and it completely throws my focus to ****. I'm using it on a Sony DCR-SX45 so it's an adapter lens rather than an actual lens that would perform much better. I know many people use adapter fisheyes and the picture quality is just fine but for whatever reason mine continues to be terrible. If I place focus and scene selection on auto, it can only focus on extremely close objects. Anything 3 feet away or more is blurry. I tried manual focus, and all of the scene selections and it still continues to be blurry. Would adding something to extend the lens further out help? I sorta remember reading that extending the lens further away from the cameras actual lens helps clear it up. Any suggestions?

This is how it came out when I had everything on auto.

Best suggestion would be to get a better auxiliary lens. Opteka is lowest bidder type crap and this is probably the best it can do.

put a UV filter in between. there needs to be space between the camera's optics and the fisheye.

Can I just use a step down then step up ring between the camera and fisheye?

that's fine too. anything to create a bit more distance. but that's not entirely the problem. I'm not familiar with the camera you are using, but the camera shouldn't have focus issues like that.
