The NiSi 77mm SMC UV Filter is a professional-grade protective filter featuring a Super Multi-Coating to effectively minimise reflections and improve light transmission. Designed to absorb ultraviolet light and reduce the bluish cast sometimes found in daylight conditions, it also serves as a permanent protector for the front element of your lens against dust, moisture, and scratches. Its ultra-slim frame is crafted from high-quality aluminium to prevent vignetting, ensuring it is suitable for use on high-resolution wide-angle optics.
