Description

Reading the MTF Chart: RF 24-105mm F4 L IS USM

Solution

A Modulation Transfer Function (MTF) chart measures a lens’ expected optical performance at the center of the picture area and measures repeatedly along the diagonal line, further and further toward the corners of the image. The higher a curve is shown on the chart, the better the lens is performing in the area the chart is measuring. As a curve moves from left to right, it displays the lens' results from center towards the corners.
