Double-sided multi-layered scratch-resistant coating reduces light reflections between lenses, delivering higher resolution and clearer images. Extra thick glass lens provides robust protection against scratches, drops, collisions, and high water pressure. CPL filter enhances landscape photography by reducing glare on water surfaces, enriching blue skies and white clouds, and improving the appearance of snowfields, flowers, and trees. ND filters available: ND16, ND32, ND64 - ND16: suitable for sunrise and sunset, seascapes, and forest streams. - ND32: ideal for waterfalls, flowing water, waves, mountains, and rivers. - ND64: for scenes with running water, traffic, motorcycles, bicycles, and similar subjects. Practical applications - Landscape and seascape shoots in bright light; use CPL to manage glare and ND16 for balanced exposure in golden hours. - Long-exposure water photography of waterfalls, rivers, and waves using ND32 or ND16 to achieve smooth water and rich detail. - Urban and vehicle scenes; use ND64 to create motion blur for moving traffic or riders while preserving scene exposure.
