Food photography Lens Choice?

I'm starting to take pictures of food and want to know which lens of mine would work best.

I'm using a Nikon D90 so take into account the crop factor.

Nikon 50mm 1.4
Sigma 18-50mm 2.8
Sigma 70-200mm 2.8

I normally take portraits looking to expand my skill set.

Nikon 50mm 1.4

Move backwards or forwards on your feet to take the crop factor into account.

Don't necessarily stick to f/1.4.

Nikon 50mm 1.4, it's beautiful x

I use a my 50mm f/1.7 and 90mm f/2.8 macro…

The 50mm would be ideal I think, perhaps a macro too.

50mm and a good lenshood.

I use a Nikon 50mm f/1.4 and for macro shots I'd use a Nikon 105mm f/2.8 Micro lens.
