I've noticed a problem that seems to be specific to my camera whenever I use my Opteka fisheye the vignetting is so bad on the left you can almost see the whole curve and then little to none on the right side.I havent tested out another fisheye lense but if anyone knows how to fix this please let me know.Thanks
