I want to get my mother a new lens for her nikon d60. She loves taking photos of the family and I'm encouraging her to learn more about portraits and lighting. I'm looking for some fast glass that would also be good for an upcoming wedding. Budget is about a grand. She has an external flash and a nikkor 18-55 3.5-5.6 and a 70-300 4-5.6 Any advice would be awesome. Her birthday is tuesday so i need to find something fast. Thanks!
