I have a Panasonic version of a wide angle adapter for my SDT750 (like a TM900, but with a 3D lens). I don't have a link to a sample, but have not noticed any degradation of picture quality. It works well for tight situations. I bought it after trying to video a shrimping trip in a small boat. I couldn't get back far enough without trying to walk on water. Another place it works well is at family gatherings, like birthdays, were the house or room is small and there are too many people.
There were much cheaper choices when I bought it. I suspect the cheap choices could have picture quality degradation and may lead to a generally poor reputation for "adapters". My guess is that Sony would make a pretty good one.
