I own the D3000. I have the 18-55 lens. Looking to get a new lens. I mainly use for leisure, taking photos of the kids, family vacations, outdoors. I have had this camera for almost 2 years and I would like to finally take the time and learn more about and capture better shots. Have been looking into the 35mm f/1.8. Would that be a good lens? Or do you have any other recommendations. Another thing I have been looking into is filters, are they worth getting? I don't know alot about them.
