This is a HAKUBA ULTIMA lens guard, 82mm. I am selling it because I am replacing my lens. Please see my profile for other notes. Instant purchase is welcome. ULTIMA is a high-quality lens filter developed for professional photographers who pursue image quality. By combining the highest quality optical glass from CORNING with the latest digital vapor deposition coating technology, it achieves optical characteristics that maximize the light-receiving sensor wavelength range of digital cameras and the highest transmittance.
