TS-E50mm f/2.8L Macro

TS-E50mm f/2.8L Macro

This standard lens, equipped with tilt-shift functionality for action in wide-ranging genres from landscape and architecture photography to close-up food photography, has undergone evolution and renewal into a high-image-quality L lens. It improves its magnification to 0.5x to tackle macro photography, even of small subjects. Its optical system employs an optimal arrangement of two UD elements to achieve high image quality that extends to the edges of the image while suppressing distortion to the limit possible. Furthermore, the lens’ special SWC and ASC coatings reduce the occurrence of flaring and ghosting. With a TS revolving mechanism that flexibly responds to shooting conditions and expanded tilt-shift amount for easier control of perspective and depth of field, this high-performance lens takes operability to the next stage.

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
