Becky's daughter wants to be a professional photographer and wants to know what to get her that is affordable. She currently uses a Canon Rebel XT with interchangeable lenses. Leo says that getting her a prime lens like an EF 50mm F1.8 is great because it's fast and sees roughly what the eye sees. It will also train her to shoot and compose images professionally. It's great for portraits and street photography. It's also very good in low light. The faster the lens, the blurrier the background while the subject is super sharp. Another option for landscapes is a wide angle lens.
