DJI's 15mm f/1.7 ASPH Prime Lens features an MFT (Micro Four Thirds) mount and is compatible with the Zenmuse X5 and X5R cameras. With a 30mm equivalent focal length, it provides a wider angle of view than is considered "normal" without straying into ultra-wide or fisheye territory. The aperture opens to f/1.7 at its widest to maximize light passage when shooting in low light conditions or to reduce depth-of-field for augmented bokeh effect. The lens's optical design incorporates three aspherical elements to reduce distortion and spherical aberration for sharper imagery with greater overall clarity.
