So I bought a new .29 30mm liquid lens for my HC 37, (which is like the 38 but in PAL format i think). I had a .6 sony wide angle lens before which had no vignetting, unfortunately it was knocked off by a hard opening so i replaced it with the much more expensive liquid lens, hoping for the same quality, but lower profile.
The liquid lens is giving me major vignetting, dispite the fact that it is quoted by cookie composites as having "No vignetting with or without filter option." Its pretty annoying, given i paid the equivalent of over $200 for it.
Anyone else having this problem? im not using a step ring by the way.
