The RevoRing MkII Landscape Kit 58-77mm is a comprehensive filter system designed for professional landscape photography applications. This kit includes the RNC77-II filter holder, the RBR-77 magnetic adapter ring, and RH1 filter holder accessories, creating a versatile solution for photographers working with lenses that have filter thread sizes ranging from 58 mm to 77 mm. The magnetic adapter ring system allows for quick filter changes without the need for threading, enabling photographers to efficiently adapt to changing lighting conditions. Made from precision-machined aluminum with brass components, the system maintains optical alignment while ensuring field readiness. The filter holder accommodates standard 100 mm square filters and features a rotating mechanism for positioning graduated filters. The magnetic connection system provides a secure hold while allowing for fast filter changes, making it suitable for time-sensitive landscape photography scenarios. The kit components are designed with minimal light intrusion in mind and feature light-sealing grooves as well as anti-reflective coatings on critical surfaces. The adapter rings have knurled edges for easy mounting and dismounting on lenses, with precise threading that prevents thread damage. The complete system weighs approximately 180 g, ensuring portability for outdoor photography expeditions. The RevoRing system is compatible with various filter types, including neutral density, graduated gray, and polarizing filters, providing creative control over exposure and light management in challenging lighting situations. The modular design allows for expansion with additional adapter rings and accessories for different lens diameters beyond the included 58-77 mm range.
