I'm seriously looking at the pro's and cons of Q500 4K and the Phantom 3. From watching many youtube video's the Q500 4k video looks waay too overexposed on sunny days and the Phantom 3 has the advantage of putting in different ND Filters to fit that day's sun exposure. Since I'm located in the Denver area and it's sunny almost everyday, having control of what ND filter I use on my camera is a big deal for getting the right exposure. I see that Yuneec give us one a one stop ND filter although that is still not enough for most sunny days here in Denver. Are there any filters available for the Q500 4K getting 2 or 3 stops?
