And both are good lenses, being paired with a D800 body. I have a few choices:
1) nikon 50/1.4 af-s
2) Nikon 50/1.4 d
3) Sigma 50/1.4
4) Nikon 50/1.8g
5) Nikon 85/1.4 d
6) Nikon 85/1.8g
7) sigma 85/1.4
I can't afford the 85/1.4g. And realistically, I'd rather go with Nikon over Sigma.
My 85/1.8d is in great shape and takes sharp pictures even close to wide open. I've held and shot with both the 50/1.8g and 50/1.4g. I think the 1.4 has better build quality and both are extremely close IQ-wise. I liked the feel of the 50/1.8g over my older 1.8d. It is a larger lens and it handles well. Lots of options here
