Slide this Aureole Landscape Filter Frame into your Benro adapter ring to fit one circular Aureole series filter and one square Aureole series filter between your lens mount and camera sensor without light leaks. Layer graduated neutral density, polarizer, and neutral density filters to create your desired look for perfectly exposed images without lens flares. Two rotation adjustment dials can rotate each of the filters inside for the best angle, allowing you to flip the linear movement of your graduated neutral density filter. This makes this filter frame the best for capturing landscape photography, where you might need to expose differently for the background versus the foreground.
