I just can't seem to get a good photograph of these little red flowers on this plant. Here's my latest attempt, with the 50mm F2.0. Notice what's happening to the edge of the flowers? It's almost like the red pixels are being shifted a pixel or two compared to the rest of the image. It doesn't seem to be CA. In-camera processing issue? The camera in question is my E620.
