The main thing to know is that your specific lens on your camera body will make the picture seem more zoomed-in than the numbers say. The 18-135mm lens actually works like a 27mm-to-202mm lens. This is great because you can get tight close-ups of Billy's crazy face or the teacher's pain without getting too close to the action. This zoom power will make the comedy look intense.

Because your camera has a great sensor, you can get a sharp picture where the person you're focused on is clear, but the ugly, clean background is slightly blurry. This makes Billy look like the most important thing in the shot. The big zoom range is also really helpful because you can shoot the wide shot of the whole hallway and then quickly zoom in for a close-up of the finger pointing without stopping to change lenses. This lets you keep up with the fast, chaotic filming without missing anything. (hopefully)
