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.

I don't like name dropping, but I did a well known canopy course recently. I was taught that, for nearly all of us, undoing the chest strap has little effect on the shape of the canopy, which in turn has little effect on the flight performance. I was told that the reason for loosening the chest strap was to make it easier to fly the canopy with our bodies; i.e. harness and combination turns. It certainly makes sense to me - I find it much more comfortable and easier to lean in the harness with the chest strap loosened off.
