How much is a decent UV-filter? How much is a front lens - of the Sigma 150-600 contemporary, so for sure no fluorite or diamonds or other expensive stuff.
And how much more shots you want to miss because of a tiny thin plate of glass which will likely break the next time it sees a pointy stone?
I bought two Sigma ceramic protectors ø 77, these are sitting at home just in case I ever remember them. I stay clear of "filter to protect my investment" - just because they are another investment and in most cases as expensive as the front element they have to protect. The front lens itself simply is thicker and more protective - and a lens hood will take more bumps and keep the stones and pointy elements in safe distance.
