It's not the size of your lens, It's how... well, it's definately the size of your lens.

One of my favorite things to do is browse online photo stores to see what I can find but not afford. Behold! The holy grail of L lenses! This is the Canon 1200mm f/5.6. It's custom made. It's used. Whatever, it's $120,000. House or Lens? One day, I will take this lens to the moon... or not. Thanks B&H! Go there, they are great. Below is a link to the demo video.
