I have been touting the Flarebuster with my PD150 at

Subject: Help with wide angle lens flares
I found a great gadget to help eliminate those pesky lens flares when I use my wide angle adapter on the PD150. It is called "FlareBuster" and is available at flarebuster.com for $20 to $30 depending on the package. What it is, is a flexible 15" rod that mounts on the camera shoe (or the tripod connection) and attaches to a clip which will hold a small french flag (included), or gobo, or filter. Simply twist the arm into position until the offending flare is eliminated. (Actually, the included flag is a bit small and I made a larger one by cutting a piece of black art card)
But I also got to thinking of some other uses for the gizmo. I do a lot of interviews for clients where I ask interviewees a series of questions, which I sometimes forget. Now I write them on a 3X5 card, attach the card to the clip, and twist the arm so the card is above the LCD screen. Also, a similar scenario for an on camera talent: they could write bullet points on a card and position it above the lens for a little prompting.
At any rate, its a great little gadget that will work on any camera and I recommend it highly. Value for dollar.
