I bought the Raynox 6600 some time ago and I think it's been working fine. Last night I filmed a shot of a window. When I saw the shot today it looked strange. The window was not even but did this in stead: /\ - in stead of l l. Is this what you call vignetting? I thought it only came when zooming in too much (I did not zoom in at all). Could it be because of low light or? I have shot in low light before with better results. Or is there something wrong with the lens?
Hope you can help clear this op for me.
