If you currently own an X5 camera system from DJI then you should be considering the Olympus 14-42mm M.Zuiko as an add on to complement the 15mm Prime lens. Because the 14-42mm is a pancake lens, it has remained light enough for the DJI gimbal to stabilise. As a result, the 14-42mm is absolutely unique in that it's the only lens available that allows you to zoom in and out through the DJI GO App.
With a 3x optical zoom and an exceptionally fast auto focus, this lens will give you much more flexibility in terms of the shots you can achieve with your drone.
The images produced by this deceptively small lens are clear, crisp and well defined.
