As a high school student, I started in this SLR "business" about 2 years ago. My first lens was the 17-40 f/4L. At that time, I had enough money to go for the 17-55 f/2.8, but I went for the L with a reason. I know that I will keep the L for a long time, like how all these other people keeps their lenses from the early 60, 70s. I wanted to grow up, and tell my kids that this was Daddy's first lens. I also purchased the 70-200mm f/4 and the 400mm f5.6
I capture my school, family, and my childhood memory with the lenses. Memories last forever, and I believe that the lens which captures them will last as long as my memories. Someday, when I see these lenses, I will be able to remember the moments I spent with my dearest friends and family.
