Dear all Nikon enthusiasts: Do you have any experience on using these two lenses? What is the difference compared with AF85mm/1.4 & AI or AF 180mm/2.8? I got a good chance to have them at decent prices, US$90 for 85mm/1.8 & US$180 for 180mm/2.8. Your comment will be helpful for me to get both or not. Best regards, Richard.
