What lens do you have now? I assume you have the kit zoom lens that came with the camera. If so, you may want to do this little experiment before you spend any money on a new lens. Run you zoom out to 35 or 50mm. put a piece of tape on it so it don't move. Then go out and shoot as if you had your new 35 or 50mm. See if you like the fixed focal length. I have both the 35 and 50, but find that I use my zoom outdoors more because there are some things that I can just not walk closer to. I like my primes at afternoon barbques or cook outs or indoor low light parties.
