Input:
These have saved my primary lens multiple times over the years. I carry a spare for photo expeditions in the rough. While I have cracked several, even if broken they will unscrew with care and you haven't trashed your primary lens. Available for multiple lenses and I have them on prime as well as big telephoto lenses. Large size saved a big expensive Canon supertele before. Good quality and no visible distortion
