Here is some sample footage taken with the HV20 + Raynox dcr/hd 6600 pro. I setup the tripod and shot 1 right after the other and did not change anything other then put the raynox lense on.. as you can see it makes a huge difference. I did notice a bit of lense flare when I played it back but I didnt put my XhA1 hood on. It was basically out of the box and onto the hv20. I will do another test today with the hood on
