Earlier this morning, Canon announced the successor to the legendary EF 35mm f/1.4L USM, - the new 35mm f/1.4L II - the lens is the world’s first to feature Canon’s newly developed Blue Spectrum Refractive optics (BR optics) ensuring sensational image quality across a diverse range of scenes from news and sports scenes to weddings.
With 4K cameras becoming more and more popular, the lenses you put in front of the sensor become even more important as to render sharp and life-like images. Canon has some amazing 4K technology already like the Canon EOS C500 and the newer XC10 4K hybrid camera, and with the upcoming Canon C300 Mark II it's a good idea to look at some facts about 4K optics.
