最有亮点的是CANON此次还表了全新的“SWC”镀膜技术

Sub Wavelength structure Coating
The 24mm F1.4 L USM II sees the debut of Canon's new 'Sub Wavelength structure Coating' (SWC) technology. Considered by Canon to be considerably more effective then their existing 'Super Spectra Coating', the new coating is applied to the inside surface of the front lens element, and is designed to minimize flare and ghosting caused by secondary reflections between the sensor surface and the lens elements, which can lead to significant image degradation in digital SLRs.

The new biomimetic coating is inspired by features found within the eyes of moths, and uses a nano-scale structure to reduce dramatically the amount of internally-reflected light in lenses that contain large curve-radius elements. It is therefore particularly effective with fast wideangles such as the new 24mm F1.4L II USM.

忘了说CANON的MTF和NIKON和SIGMA一样,都是电脑计算的理论MTF
而不是实测的MTF,目前只有ZEISS和LEICA的MTF是实测值.

实测的MTF的参考网站就是著名鼎鼎的:
