Lindsey Optics has put a twist on FSND filters with its new range of Brilliant Rota-Grads, rotating full spectrum graduated neutral density filters which fit directly onto 4X6.5″ rod-mounted matte boxes for the first time ever.
The new Rota-Grads offer the benefits of FSND tech with a choice of densities and a proprietary rotating tray design for practical user advantages, such as minimized filter handling, larger filter aperture, easy alignment and quicker orientation. It also features a 138mm round graduated FSND filter installed in a geared rotating tray mount that fits into a single matte box slot and a geared thumbwheel that can be set using a simple sliding Rota-Lock.
The Brilliant solution offers a significantly larger aperture than other alternatives, enabling coverage of both large diameter and wide-angle lenses, providing a generous 5.2-inch opening that remains constant at any rotation angle. The Rota-Grads are available in 4 densities: ND 0.3 (1 stop), ND 0.6 (2 stops), ND 0.9 (3 stops) and ND 1.2 (4 stops), attenuating the full spectrum of light including UV, visible and infrared. The filters feature both AR and Easy Clean coatings for improved handling.
