It suppresses glass distortion to the limit and achieves ultra-high resolution. [Newly developed, ultra-low reflection ZR01 coat & high-transmission optical lens] The newly developed "ZR01 coat" is used for the lens coating. Ultra-low reflection of 0.1% surface reflection is achieved. It suppresses disadvantages such as flare and ghosting caused by filter attachment, 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" that reduces the filter's biting into the lens during installation and the "knurling" that improves finger grip when attaching and detaching the filter make it easy to attach and remove. [Eco-package only for Amazon] This is an eco-package that differs from the normal packaging, only for Amazon.
