Hey guys,im kinda new to portrait photography and i wanna get into it. I need some suggestions and opinions. Im thinking of getting Sigma 1.4 cause i heard the bokeh is better than Nikon. But im still not sure which to get. Sigma 1.4,Nikon 1.4G or Nikon 1.8G? I love taking potrait shots/candid/group. I heard a lot of comments regarding Sigma having issues w focusing and stuff. For Nikon,i know that regarding the edge,its better than Sigma. Also,it will really help if you guys can roughly give me some rough quotes on the prices! Thanks!
