I was out for a walk testing a new lens on my panasonic g9, i didnâ€™t see anything unusual when i was shooting this video (thunder clouds forming). when i reviewed the images/videos later i saw the object at the top of the frame. this video was captured at 30p on a micro four thirds sensor. i didnâ€™t hear any sound. insect or invader? i also saw a helicopter fly over a few minutes prior to the sighting.
