DJI DL/DL-S LENS User Guide
MTF
An MTF (Modulation Transfer Function) chart is used to measure the ability of a lens to
reproduce contrast and resolve details. Low spatial frequencies reflect overall contrast, and
high spatial frequencies reflect detail resolution. Image Height indicates the distance of a given
point on the lens from the center of the sensor. MTF 100% indicates perfect performance.
