The B+W UV (010) filter with a 30.5 mm thread diameter is a professional optical filter designed to protect camera lenses and filter ultraviolet light. This high-quality filter effectively blocks UV rays that can cause haze and color casts in outdoor photography, especially at high altitudes or near water. Made from precision-crafted German Schott glass, the filter maintains optical clarity while providing robust protection for the front lens against dust, moisture, and scratches. The brass filter ring ensures smooth attachment and prevents jamming, while the slim profile design minimizes vignetting even with wide-angle lenses. The multi-resistant coating on both sides repels water, oil, and fingerprints, making cleaning easier and preserving transmission properties. With a thread size of 30.5 mm, this filter is compatible with various compact cameras, camcorders, and specific lens models that require this diameter. The neutral color rendition preserves natural tones without affecting exposure values, making it suitable for both digital and analog photography applications. The sturdy construction and consistent optical performance make this UV filter a reliable choice for photographers seeking lens protection without compromising image quality in various shooting situations.
