Compatible Lenses
DJI DL/DL-S Lenses are compatible with the DJI DL-Mount of the Zenmuse X7 (a diameter of 58
mm). When used with the Zenmuse X7, the crop factor is 1.5 for still shooting, and 1.6 for video
recording. The DL-S 16 mm F2.8 ND ASPH lens has a built-in ND 4 lter and it can record video
of Super 35 mm size. The image circles of the DJI 24mm, 35mm, and 50mm are larger than the
sensor size of Zenmuse X7, and are capable of creating professional video of lm quality in S35
mode. Their built-in leaf shutter supports the shutter speed of up to 1/1000s, which can eciently
avoid video lag during high speed shooting.
MTF
An MTF 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. Both are measured in LP/mm. Image Height indicates the distance of a given point on
the lens from the center of the sensor. MTF 100% indicates perfect performance.
