 finalised version of the upcoming lens Canon BR Optics
Canon’s proprietary Blue Spectrum Refractive Optics (BR Optics) incorporate a new organic optical material with unique anomalous dispersion characteristics for use in camera lenses. The molecular design of BR Optics refracts blue light (short wavelength spectrum) to a greater degree than other existing optical technologies including UD glass, Super UD glass and Fluorite, to control color fringing as effectively as possible. When placed between convex and concave lens elements made from conventional optical glass materials, BR Optics help to produce sharp images with outstanding contrast and color fidelity by thoroughly reducing axial chromatic aberration.
We have already posted the image of Canon upcoming Megapixel monster image (may be called Canon 5DSR II). Take a look at the post here.
