I am looking for all the things I need to photograph my best friends wedding. She asked me at the last minute so I am very nervous. I am not a photographer, well not of things like weddings. I do nature shots. Landscapes, flowers, things like that are my speciality. This will be my first wedding and I need to find the best canon wedding lens available. I know that Canon has some great lenses to choose from, like the 24-70mm and the 24-105mm, I just need to do some research and find out which lens will be the best for my needs.
