I recently acquired a new Inspire 2 with the stock X4S camera. I'd like to upgrade the camera setup to have zoom capability using DJI GO 4. It's my understanding that the X5S and Olympus 14-42mm/3.5-5.6 "pancake" lens combination would be one of the more cost effective ways of gaining zoom capability. I'm looking for high quality (like new in appearance and functionality) camera and lens only. Thanks.
