[QUOTE="Eyelight, post: 369896, member: 24753"] This may sound like a cop-out, but everything about an image is a combination of light, lens, sensor and processing. So, yes it is subject related and yes it is lens related and possibly a little sensor and/or processing related. Not necessarily a lens problem, but some lenses will do better than others and the same lens may do better by changing aperture. Looking at the purple fringe on the near wing, it appears the effect may be enhanced due to the angle the light coming from above and behind the bird. Is this because there is more exposure maybe, in combination with a little blur.... maybe??? So the lens delivers this slightly blurred edge that's over-exposed compared to the pixel next door and it shows up at the sensor minus some color, so the sensor sees purple. Can you see this in the final display of the image? [/QUOTE]
