Brand new, unopened. Brand: Kenko Retail Price: 22,800 yen [Lens protection filter with the evolved ultra-high resolution floating frame system] The "floating frame" system, which minimizes stress on the glass and maximizes the original descriptive power of the lens, has been further enhanced. It minimizes glass distortion to the extreme and achieves ultra-high resolution. [Newly developed, ultra-low reflection ZR01 coating & high-transmission optical lens] The lens coating uses the newly developed "ZR01 coating." It achieves an ultra-low reflection of 0.1% on the surface. It suppresses disadvantages such as flare and ghosting caused by the filter, and maximizes performance while protecting the lens. [Super-strong water-repellent and oil-repellent coating] The strong water-repellent and oil-repellent coating provides peace of mind even when shooting outdoors. Even if water or dirt adheres, you can quickly wipe it off and continue shooting. [Dry lube treatment & knurling for improved operability] The "dry lube (lubrication) treatment" reduces the filter's tendency to get stuck on the lens during installation, and the "knurling" improves finger grip when attaching and detaching the filter, making it easy to attach and remove. [Amazon's eco-friendly packaging only] This is an eco-friendly package exclusive to Amazon, with a different packaging state than usual.
