LimitBreak Posted August 27, 2015 Share Posted August 27, 2015 CANON DEVELOPS NEW CAMERA-LENS OPTICAL ELEMENT THAT ENABLES EXTREMELY HIGH LEVELS OF CHROMATIC ABERRATION CORRECTIONThe new Canon-developed BR optical element offers characteristics that significantly refract blue light, which lies within the short-wavelength range, to achieve impressive levels of chromatic aberration correction for outstanding imaging performance.Natural light, or white light, comprises a spectrum of wavelengths, or colors, each of which realizes a unique refractive index when passing through a lens. As all colors do not converge on the same point, this disparity causes chromatic aberrations, or color fringing, to occur in an image. http://2.static.img-dpreview.com/files/p/E~TS520x0~articles/9530547937/mtf.jpeg http://***URL removed***/articles/9530547937/canon-ef-35mm-f1-4l-ii-usm-blue-spectrum-refractive-optics Quote Link to comment Share on other sites More sharing options...
