This topic, for some reason, draws passion. For that reason, let me outline my case for hoods. Hoods will help protect against:
And, generally, lens hoods ought to be less expensive than a filter (unless you’re talking about that crazy priced Fuji X100 series hood).
Yes, it’s cheaper to replace a filter than a lens. But I’m persuaded that any extra glass will diminish your image just a bit.
Of course, I’m talking about the UV, Sky, and similar filters. Polarizers, ND’s, and such are quite useful. We’ll try to cover those a bit later.
