Optical Elements that can be used to increase the magnification of a lens. Close-Up Lenses (Diopters) are used when you need to get really close-up images of small objects. While not a true macro lens, they are lightweight and quick to use with standard matte boxes and filter holders. Lindsey Optics Round Drop-In Diopters are available in two standard cine sizes of 4 1/2 Inch Round and 138mm Round.
4.5" Round Drop-In Diopters are available in 4 strengths including +1/2, +1, +2 and +3.
138mm Round Drop-In Diopters are available in 5 strengths including +1/4, 1/2, +1, +2 and +3.
Use the +1/4 when you need to get just a tiny bit closer. The +1 gets you close . . . the +3 gets you VERY close.
Lindsey Optics Brilliant Filters are made from the finest optical glass. They feature rock hard, multi-layer BROADBAND anti-reflective coating. This dramatically reduces light loss and flare. Contrast, color saturation and image quality are preserved.
