I just have a quick question for anyone who has used this, and the 50mm 1.4 lens... I've completely LOVED my Nikon 50mm 1.4, it's incredibly sharp and has been perfect for my purposes. Now that I'm almost saved up enough for my camera upgrade (D700 soon!!!!), I'm thinking I may need a longer portrait lens on a full frame. I've heard really great things about the 85mm 1.8..and it's pretty afordable next to the other lenses I've considered. I've also heard that it's nice and sharp, too.. But I was hoping to hear from anyone here who has experience with both lenses.. Is it "as sharp" as my 50mm?? If it's not as sharp...I might hold off and make due with the 50mm on a full frame until I can afford the 85 1.4, or one of the other lenses on my long list =P Thanks!
