82855: PUMP,RECIPROCATING.
- Reduces reflection on non-metallic surfaces and enhances colour saturation and image contrast - Puts contrast and depth in the picture, the sky gets blue, the clouds get white and the colours become clearer - According to the position of the filter, non-metallic reflections (water, plastic, glass, etc.) are removed - A shooting angle of 30-40° to the reflective surface will give the best effects - No vignetting (dark shading of picture corners) - For wide-angle, wide-angle zoom and travel zoom lenses and especially for fast AF lenses with integrated motor drive (front lens focus) - Front thread for other filters or a lens hood - Protects the lens against scratches, dust and fingerprints - Tempered glass - New lens glass of superior quality - Special filter with ultra flat rotary mount (4.5 mm) - HTMC coating: four layers of coating are vapour-deposited on each side which minimizes light reflections and optimizes light transmission - Very low weight This part is cataloged in the U.S. Government catalog under NSN 4320-01-270-4953, indicating validated use in U.S. government and defense logistics supply chains.
