Thanks for all your replies so far. Stephen, so apart from weird vignetting, have you had that blur on one side of the screen too? Do you think it's the camera? The primes seem fine. But my zoom, yeesh! What have you done to correct it? Sam

Hi, I have a Cooke 20-100 Zoom lens on my RED. At the widest end I get vignetting only down the right side of screen. Shooting wide open at most lengths also has blur only on the right side of the screen. When I stop down to 5.6 the blur goes away. Would this be an issue with the lens or with the RED? I'm uncertain of how old this lens is and whether that could be a contributing factor. Any help with this would be much appreciated! Cheers, Sam
