Nikon D3000 and sigma 50mm DG macro lens

[zmt]

Hello,

I own a Nikon D3000 camera (my first DSRL!) and just today I received from my father a Sigma AF 50mm F2,8 DG macro lens as Xmas gift. The thing is that once the lens is installed the camera does not even turn on. I've checked Sigma's website and the lens should work with D3000. Anyone having the same problem? Thank you!

Just a quick note to those interested: I contacted Sigma and their very short answer was:
"Unfortunately this lens would probably need a firmware upgrade to allow you to at least use it in manual modes.
The AF however will not work as it is a non motorized lens."

So if you own the D3000 be ware and do not get this lens!
