It's good practice to put a Skylight filter on any lens you use. You may get upset paying £20 for a filter, but it does save the lens in most situations.
For videos, I took one of those clear vanity cases with aluminium sides, drilled a whole in the bottom, mounted a QD shoe from a tripod through it, into the camera. Operate by remote control.
The sides can be replaced with thicker polycarbonate etc if needed. Works for me. I even just stick it on the tripod in a suitable place on the field and go play.
The second cover down, i also have one similar, though mine is more canvas material and a bit more substantial looking. Because I cant afford a massive Image Stabiliser lens, you can actually sleeve it out, inside with a bit of drain pipe, which will certainly protect the lens from impacts on the top and sides, when combined with the front protection, if you see what I mean.
