Title: You can have the wide angle adapter if vignette doesn't bother you.
Review: I bought the Opteka 0.5X wide angle adapter for my Panasonic SDC-SD5 HD Camcorder last year but never used. Reason: Terrible vignette when the camera lens is set at its widest angle. This 0.5X wide angle adapter is simply for those who are not bothered by the four super dark corners in the widest wide-angle shots. When the adapter was designed, Opteka had chosen the lightness over avoiding vignette. What a shame!
