In need of lens adapter

My DSLR is an Olympus E-600, and I'm interested in purchasing a Nikkor 35mm f/1.8. Since I'm new to photography and choosing lenses I need help finding the right adapter!

Buying a Nikon lens for an olympus camera is a $400 mistake

an adapter takes away all autofocus, possibly metering, and will take away 1-2 stops of light.
Olympus basically stopped their DSLR camera line and is now focusing on their micro 4/3rds cameras.
you can use the 4/3rds lenses on your DSLR

I hate to say it, but you might want to consider moving to another brand of DSLR such as Canon or Nikon
