Thanks Bryan, yes the site is working normally now.

I am saying its just my unfortunate copy that has the back-focus issue, i have read its not uncommon with many 120-400 copies. just didnt expect it to be that profound , i hope i made it obvious in my samples. I suspect it all may be related to OS workings as its moving elements around (as i am told at least) and somewhere in the process they lost their perfect alignment. I wrote to local Sigma representative and still waiting for their response.

I am thinking now that might be the case maybe with many potential buyers that rejected the lens after a test drive all reporting it as "too soft" which would make sense if all those samples were similar to mine: inacurate focus and soft @ f/8. Like i said if working properly is sharp enough lens, a keeper and certainly a good bargain
