Maybe it's just me, but I don't understand what the big deal is with a little vignette. Zoom in a little or crop in editing and it's gone.
Yeah it be nice if there was no vignette, but these lenses are not specifically made for one camera or housing. They get used on a variety of systems and a little vignette is the result. The wider the adapter, the greater the chances for distortion and vignette.
If the FOV is 100 degrees with the vignette, it's 97 degrees after zoom/crop.
You have the right idea about trying out a lens 1st. Be careful though. Many times you can't see the vignette on the camcorder LCD, only to find it shows up when displayed on a computer monitor. For me, distortion, FOV and corner sharpness are more important than a little vignette. Play your clip at full resolution on a big HDTV or monitor to see the real picture.
