EF35mm f/1.4L II USM

EF35mm f/1.4L II USM

Taking the concept of evolution to a higher level, this innovative lens greatly expands the performance potential of 35mm fixed focal length lenses. The flagship of Canon’s large-diameter prime lens lineup, the new EF35mm f/1.4L II USM is a distillation of the most advanced optical technologies. A new BR optical element, incorporated in an EF lens for the first time, achieves radical correction of residual secondary chromatic aberration (color fringing) at a level that has been difficult for large-diameter lenses. Even when photographing night scenes or celestial objects with the diaphragm wide open, each and every element is rendered clearly, achieving sharp, crisp image quality from the center to the periphery of the frame. Superior operability ensures the ability to respond to even the most fleeting of encounters. Landscapes, portraits or close-up photography – regardless of your choice of subject, you’re sure to be impressed with the evolution of our new flagship lens.

The more the S and M curves are in line, the more natural the blurred image becomes.

Modulation Transfer Function, or MTF, is a method of evaluating lens performance using contrast reproduction ratio. When evaluating the electrical characteristics of audio equipment, one important measure of performance is frequency response. This indicates the fidelity of the reproduced sound with respect to the source sound as it passes through the microphone, recording and playback circuits, and finally the speakers. When the reproduction is accurate, the equipment is classified as “hi-fi,” or “high fidelity.”
In the same way, when a lens is viewed as a transmission system for optical signals, measuring the frequency response of the optical system reveals whether the optical signal is transmitted faithfully. For a lens, the equivalent of frequency is “spatial frequency,” which indicates how many patterns, or cycles, of changes in sinusoidal density are present in a 1 mm width. Accordingly, the unit of spatial frequency is lines per mm, as opposed to Hz in electrical systems.

The MTF characteristics shown on this website are 10 lines/mm and 30 lines/mm, where the horizontal axis indicates image height (the distance on a diagonal line from the center of the image, in mm) with the image center set to 0, and the vertical axis indicates contrast. The closer the 10-line/mm curve is to 1, the better the contrast and clarity of the lens; the closer the 30-line/mm curve is to 1, the better the resolving power and sharpness of the lens. Although a good balance between both of these is important for a lens to be sharp and clear, a lens is generally said to offer excellent image quality if the 10-line/mm curve is greater than 0.8, or satisfactory image quality if greater than 0.6.

Resolving power and contrast are both good

Contrast is good; resolving power is poor
