Does vignetting occur with the OpticZoom?
Yes, but only below the 2x zoom position of the Kodak DC26X and DC290 cameras. Above 2x, the pictures are fine. Vignetting has been reported on some other cameras due to their shorter focal lengths. Generally speaking the vignetting is eliminated above 2.5x zoom. (Vignetting or “optical tunneling” occurs when light is blocked by the edges of optical devices. In mild cases, it appears as dark areas in the corners of an image. In more severe cases, the desired image appears inside a dark circle, as it it were being viewed through a tunnel or pipe.
