Hi I am a new member

[ramalone]

I am a new member and am also new to digital photography. I have a Nikon D90 with the 18-105 mm kit lens and a 50mm F1.8 prime lens. I am lsearching for a good wide angle lens and came across a sigma 18-50mm EX DC but discovered it has a 4/3 digital format. Does anybody know of thsi format works with the Nikon D90 camera? Thanks for your help.
