EF70-200mm f/4L IS II USM

EF70-200mm f/4L IS II USM

The chance for the perfect shot comes in an instant. To capture such a fleeting scene more vividly, we greatly raised the performance of our standard f/4 telephoto lens. The EF70-200mm f/4L IS II USM offers an improved image stabilization effect equivalent to a shutter speed five stops* faster. It features three IS modes: Mode 1, perfect for portraits and other static subjects; Mode 2, optimal for panning shots of subjects such as motor sports or trains; and Mode 3, for sports or other scenarios involving subjects that move irregularly and quickly. With an adaptability rich in variety, the EF70-200mm f/4L IS II USM shortens the minimum shooting distance to 1m, taking you a step closer to shots with true impact. The single fluorite element and two UD elements of its optical system deliver high-resolution and high-contrast imaging. This telephoto lens brings enhanced durability and mobility to a compact and lightweight body.

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
