Can you identify this lens?

I stubled across this lens on an auction site but not sure if it is the macro version or not. The seller doesnt know either.

Its a Sigma 400mm APO F5.6

Cheers.

Thanks - I dont see this particular one in the 3rd party lens reviews. There is a 400 APO but it looks different.
Any idea what it's worth or if its worth buying?

I have it, but not in APO version.

Is crap. I have been unable to make photo in focus. The focusing ring is extremely loose. So I never use it.

Would you mean the physical textured ring on the outside of the lens barrel, or worse - that the internal fosucing mechanism might have major issues?

Yes, I mean the physical textured ring on the outside of the lens barrel.

For Manual Focus I like that the ring shows some resistance when turned, and I don't see this in this lens.

Maybe I got a bad copy. I bought it second hand.
