There certainly are some lenses that give you cause for pause when it comes to physical protection. With me, it's the Nikkor 14-24 f/2.8G. The front of that lens looks like a big, glass bowl. All it would take is one little smack from "tripod dude" to trash an $1,800 lens. Unfortunately, there's no filter ring on that baby, so I just have to guard it religiously. I rarely take it on charters anyway, because the perspective distortion on trestle shots (the only place I would really need it) is so strong that it can be difficult to correct in post. For wide angle shots, I typically bring the Nikkor 16-35 f/4G, which is significantly lighter, does accept a filter and just "looks" a whole lot less vulnerable.
