Canon has announced a new lens for photography pros and amateurs to try out. The new lens is notable because it is the first L-Series lens to use Canon’s proprietary blue spectrum refractive optics (BR Optics). The special optics are specifically designed to deliver photographers a higher level of chromatic aberration correction for improved image quality.

The new lens is the EF 35mm f/1.4L II USM lens and the BR optics uses a new organic optical material with special anomalous dispersion characteristics designed specifically for use in camera lenses. The design of the optics refracts blue light in the short wavelength spectrum to a greater degree than other optical tech.

BR Optics refracts that blue spectrum light to a greater degree than UD glass, Super UD glass, and Fluroite. Canon places the BR optics between convex and concave lens elements made of conventional optical glass to deliver outstanding contrast and color fidelity by reducing axial chromatic aberration.

The new EF 35mm f/1.4L II USM lens is compatible with 72mm filters and will come with a lens hood and lens pouch. It will hit the retail market in October at a price of $1799.
