Setup, Compatibility & Care
The 77mm Tiffen Glimmerglass 2 Circular Polarising Filter is designed to screw directly onto lenses with a matching 77mm filter thread. If your lens has a different diameter, a step-up ring may be used, though this may cause vignetting on ultra-wide lenses. To use the polarizer, slowly rotate the outer ring of the filter while observing the scene through your viewfinder or rear LCD until the desired reflection reduction is achieved. For care, keep the glass free of dust using a bulb blower and wipe away smudges with a high-quality microfiber lens cloth. Always store the filter in its protective case when not in use to prevent scratching the optical surface.
