I have a Nikon D5000 w/ the kit lens (AF-S Nikkor 18-55) right now and am looking at getting another lens. I am new to photography but am mostly interested in taking portrait photography of kids & families. I like close-ups and full length shots. I can't afford top of the line, but also don't want to spend any amount of money if it isn't going to be good quality-so I guess you can say I am trying to get the most bang for the buck! Any suggestions on what would be the next best lens to get?
