MTF Chart

The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens’ performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).
The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.

*The MTF chart depicts the result at the wide-open aperture.
*For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed.

Distortion

effective distortion

When you take a picture of a lattice pattern, it will appear as the blue dotted line shows. The red line illustrates how the lattice pattern will appear in the actual picture when any lens distortion is taken into account.

relative distortion

In this chart, the horizontal axis shows the ideal image height (the distance from the center to the edge of the image [mm]). The vertical axis shows the extent of distortion. The extent of distortion is represented by how much Y, which is the actual image height, grows (or shrinks) against Y0 which is the ideal image height.

When you take the picture of a square object, if the distortion amount shows a minus value, the image will be seen as expanded (Barrel distortion). If the distortion amount is a plus value, it will be seen as a recessed (Pincushion distortion). When the distortion value is close to 0, the appearance of distortion is very minimal.

Vignetting

The horizontal axis shows the image height (the distance from the center to the edge of the image [mm]).The vertical axis shows the amount of light in the image (based on the amount of light in the image center being 100%). If the peripheral amount of light is lower than the center, the four corners of image will be darker (vignetting).
