Is sigma 85mm 1.4 as good as sigma 50mm 1.4?

[architectfadi]

I already have the Sigma 50mm 1.4 (Nikon fit), I love and I think its great. Does anyone know if the Sigma 85mm 1.4 is as good (Sharpness, build quality & speed) because I would like to get the 85mm for portrait shots?

Any thoughts are much appreciated
