looking at getting a 50mm prime for my d80 and am just wondering which one to get out of the new Nikon 50mm f1.4 AF-S Lens or the Sigma 50mm F1.4 EX DG HSM the sigma seems to be 310ish in some places and the nikon 260ish, not really had a proper look around for a good price, i have 3 sigma ex lens at the moment and i cant fault them so am leaning more towards the sigma 

now i just need my bonus next month and am sorted
