Hello, this is my first post but I have read a lot in the forum. I appreciate the contributions of the forum members, and I look forward to contributing myself in the future. I recently started getting into digital photography, but one question I have is about the need for expensive lenses now that post processing has become so advanced. I have the kit 18-55 lens and the 55-200 that came with my camera, and was wondering if it would be worth the $ to upgrade. Yes, I know I need to learn more about how to use my camera before I spend the money, but I have previous experience and am studying/experimenting a lot, and I pretty much have the basics down in terms of exposure, shutter speed, ISO, etc. I'm going to Honfleur, the Loire Valley, and Paris this summer and I want my pictures to be as good as possible. Thoughts?
