That's for the old Minolta Manual Focus mount. It won't work without an adapter. But you can get one at Gadgetinfinity.com, like JimC already pointed out.

Also, image stabilization won't work properly.

i thought the image stabillization was built into the camera ?
i take it you don't think it's a good buy ?? you certainly don't sound very positive about it ?

It costs 109.99 plus € 42.73 to hang it on your camera. (€ 53.79 if you want focus confirmation. I would.)

It's manual focus, manual exposure, and a fixed focal length.

If my exchange rate calculator is correct, that's slightly cheaper than the Tamron 70-300 Di LD at Jessops, but it would get you a new, autofocus, autoexposure, zoom lens with digital coatings, albeit not quite as long.

This 400mm Sigma is probably a better deal than the other stuff we've discussed, but I'd still go with the Tamron. Birds and small critters might be tough with a maximum of 300mm, but 400mm won't be a lot better.

The camera determines how much to compensate for camera shake by quering the lens as to its focal length. This Sigma 400mm and all those T-Mount lenses don't report their focal length to the camera, so it presumes 50mm. The longer the lens, the more the stabilization will underestimate and undercompensate for camera shake.

ok i see, just a thought but as my camera body is the Sony Alpha A300 the 400mm lens would be the EQ of 600mm and the 300mm would work out roughly 450mm ?
which thinking about it (i was working in old money) i would have my 500mm or there abouts with either the sigma or the Tamron, also by fitting say a 1.4x converter to say the 300mm zoom i wouldn't be pushing it to much and destroying the quality as much would I ???
I think after all that has been said then my best option still lies with the brand new Tamron 70 - 300mm which I can buy locally for 129 (shop called photosense)
shame that sigma 400mm wasn't A/F as it would have been almost perfect for my needs, ahh well one may come up later in the year

I've had some luck with my 1.4X and 1.5X TCs. So long as you don't shoot anything with high contrast, you shouldn't have any real trouble.

Make sure the Tamron is the Di LD. Tamron also makes an LD that isn't the Di, so it doesn't have the digitral coatings.
