Brief test on Nikon D3, then I bought one for my A900. The final opinion is based on A900 results. I should point out that I have NOT used a Sony 70-200mm SSM, only a Konica Minolta era version. The Sigma is better than my Minolta 70-200mm was for most of the subjects I shoot, on full frame. Richard (son) reckons the 70-200mm Nikkor is much better for focus speed and general handling, but he has also bought the Sigma. I know for a fact the Sigma is a better lens on full frame than the current Nikkor, but not as good as the older 80-200mm AF-S Nikkor. So do most informed Nikon owners

Sony owners may be harder to convince, they have paid a bundle for the 70-200mm and will not easily accept that a third party lens at third of the price could be a better all-round choice (that is, good on FF as well as APS-C).

Funny that I write down the question the wrong way, but still get very usefull answer David !
You probably know of my crazy issue with the 70200G. I have decided to go two ways for a while. So I'm going to buy myself a D300 in exchange of my A700-kit (do have to pay some extra but it's good deal). I will solve the issue with the 70200G myself, either at Geissler (Germany, if the can really fix it) or at Sony Japan. Then I will test the lens again and decide if I will stay with Sony or not. In the mean while I bought an A300 second hand to go with the remaining lenses so my wife ( and kids, they love it) can get a grip of DSLRS as well.
The info about the 70200 Sigma on Nikon is usefull cause I won't be able to pay for the Nikkor variant anyway. And the Sigma is FF suitable. To go with this, Sigma plan to add OS to it (next year, dutch Sigma rep.). With a little patience...
However, my question was about the 18-250. So it should have been:
David, did you test the 18-250 on a Nikon mount or Sony mount camera ?
