Hello fellow photographers! What lens is stuck on your camera?

I'm a Canon shooter, with a Canon 60D with the 18-200mm IS lens and a beautiful 10-22mm wide angle lens. I want to expand my lens gear, but I'm not 100% sure on what to get. So I want to see what the fellow reddit photographers use and why it is stuck on your camera.

Note, I shoot everything and anything and it's mostly a hobby for myself.

Even if you are Nikon, Sony or whatever, talk about what lens is always on your camera or next to always on your camera. :)
