PolarPro M3 polarizing filter has a problem with sunlight reflecting from the “golden” glass mount and showing itself in the image frame corner. NOT A GOOD LOOK.
You can fly over the DCR parks but not take off or land without a special permit. Many of the DCR parks are under Logan Airport’s “class B” airspace and need a LAANCE clearance to fly.
I for one fly with the Zoom for both stills and video. With the money saved over the Pro make sure to buy the Smart Controller if you want to fly in both the heat and cold.
