It is a characteristic of a digital sensor that uses Bayer
matrix rendering to achieve RGB images, and the effect varies
considerably depending upon a number of factors, including:
- lens flare
- contrast ratio of the scene elements in question
- sensor data to RGB rendering
- sensor pixel isolation
Since the effect is variable and changes radically depending
upon these and other factors, it is hard to come up with a
single kind of fix that would be useful in all cases.
Particularly with an interchangeable lens camera that can be
fitted with a huge range of lenses.
Most of the manufacturers are working on improving this kind of
imaging at the sensor/in-camera rendering level constantly, but
there are limits to what can be achieved that way. The best
solutions have to be tailored to the specific
scene/lens/exposure combination.
It's a minor annoyance in most cases nowadays. Just like issues
with film cameras in extreme lighting circumstances, once you
know what it is, you can work around it very easiy and
successfully in all but the most extreme cases, where you are
best to simply avoid the problem.
