Thank you for viewing. Price reduced. This is a Kenko Zeta EX C-PL 77mm polarizing filter. It's a higher-end, special model than the standard "Zeta," with increased light transmission. It's a high-quality PL filter that can deepen the blue of the sky in landscape photography and reduce reflections on water surfaces and glass. 【Condition】No discoloration. I've hardly used it since I bought it, so it's in near-new condition. There are no noticeable scratches or dirt on the glass surface, and I think it's in beautiful condition. 【Included Items】 Original box and Zeta filter case included. It can be attached to lenses with a 77mm filter diameter. Retail Price (Suggested Retail Price) • Manufacturer's Suggested Retail Price: 29,700 yen (tax included) Purchase Price I think it was around 18,000 yen to 20,000 yen. Features of (Zeta EX) • Compared to standard PL filters, it has significantly higher specifications. • High-Transmission Polarizing Film: As stated on the package, the biggest feature is that it's "approximately 1EV brighter than before." It's useful in situations where you want to increase the shutter speed because the viewfinder is less likely to become dark. • Ultra-thin and Lightweight: The glass thickness is only 0.8mm, making it less likely to cause vignetting (darkening of the corners) even when used with wide-angle lenses. • This product is discontinued. Please consider this item, as it is a used item stored at home. #Kenko #Kenko #CircularPL #77mm #PolarizingFilter
