Magnification: +3.5 Thread Size: 72mm This line of advanced Achromatic Diopters provides video zoom lenses with more close-up range and magnification, while maintaining zoom capabilities — without compromising image quality. Common single element diopters permit focusing at close camera-to-subject distances at the expense of image clarity, a pin cushioning effect occurs. Instead, Achromatic Diopters feature two highly corrected glass elements which minimize chromatic aberration and distortion, creating an image with edge-to-edge sharpness. These diopters also feature a hard anti-reflective coating. This dramatically reduces light loss and flare while helping to further ensure proper color, contrast and overall image quality.
