Any info about Sigma 15mm f2.8 FD-mount fisheye?

I saw this lens recently on sale and tried to found some photos and specs etc. but found pretty much nothing instead. Does anyone have ever owned/still owning this lens and is it any good? sharpness?

I think sigma made this with minolta md-mount also. Thats all i know. Im interested to see how it performs on a Sony a7-series body.

And how about the similarities with the newer sigma 15mm EX DG-lens?

I think you search 16mm you'll get better results

But why? Im not interested about the 16mm filtermatic one. Here's a photo of the 15mm: https://kameratori.fi/images/products/sigma-15mm-fisheye-7039_orig.jpg
