hey everyone, I just got a filter and lens set for my sony cyber shot h-7. The filters aren't big enough to fit over the wide lens that came with the set. They also create a vignette. Vignette aside, should I get new filters that fit over the end of the conversion lens? Does it change the focal point when the filters are set behind a conversion (or any?) lens? If it took my camera off the wide-angle lens setting, I can zoom in past the vignette. Does this defeat the purpose of the wide-angle lens? Thanks!
