I'm shopping around for a good indoor lens, for fairly low light situations. I have the 18-55mm, f/3.5-5.6 kit lens and the 55-200mm, f/4-5.6 telephoto lens already, but I'm thinking I need a faster lens for better indoor pictures, without needing the flash. The two on Nikon's page that I'm scouting are here: 35mm f/1.8 http://www.nikonusa.com/Nikon-....html
and here: 50 mm f/1.8 http://www.nikonusa.com/Nikon-....html
Am I barking up the right tree, or are there more options I need to look at? One thing that I believe really limits me is that my D3100 doesn't have an autofocus motor built in, so any lens I buy has to be the AF-S series, which has its own motor. Thanks for the help.
