Benefitting from a superior multilayer lens coating, the Sigma Lens Hood for 18-200 mm F 3.5-6.3 DC Macro OS HSM LH676-01 successfully wards off the excessively reflective properties of digital image sensors. This results in radically diminished levels of flare and ghosting. The lens hood also comes with a specially constructed black rimmed glass for eradicating unwanted reflections that occur internally. Plus, this lens hood is built using superlative UV filters, which decrease harmful ultraviolet light while safeguarding your lens during regular photography. The Sigma Lens Hood for 18-200 mm F 3.5-6.3 DC Macro OS HSM LH676-01 is further equipped with circular polarizing (CP) filters for obliterating reflections that emanate from objects such as water as glass. These filters also deepen the profoundness of clear blue skies. Moreover, the CP filters are enclosed inside an ultra-slim metal ring, which helps prevent any occurrences of vignettes while using this lens hood with wide-angle lenses. One important thing that needs to be noted is that the Sigma Lens Hood for 18-200 mm F 3.5-6.3 DC Macro OS HSM LH676-01 is designed to be attached to the front cap of your lens.
