I've been using a DSLR for a while, but learned on an old fully manual film camera. My lenses in the past have not gone down in F-stop past 3.5. I would really like something in the 1.8 range. What lenses would you recommend and if I did get one that had that F-stop what is the focal distance be for that lens? Also I'm going to upgrade to a Nikon D7000. Thanks everyone!
