The Canon EF 35mm f/1.4L II USM gives exciting performance: it is the best 35mm lens on the market. Image sharpness is unbelievably high, both at the centre and at the edges, even at f/1.4. Canon uses key technologies as SubWavelength Structure Coating (SWC) to increase light transmission, reducing both flare and ghost images. In addition a Blue Spectrum Refractive (BR) lens, made of organic material, enables very efficient correction of axial chromatic aberration that’s impossible to correct by software. The 9-bladed aperture diaphragm creates very attractive bokeh and a seal on the mount protects the camera from dust and moisture.
