What causes this fringe around the bird...........is it camera shake or something else. THis is a JPG of the un edited RAW file?

It looks like when the light bends around a back-lit image. Each lens and in this case sensor design has to interpret that additional bit of photons somehow. There is always a bit of diffraction that occurs when the light bends around something, especially if the something is really sharp. The light is actinic in the source so it registers as blue, in particular I think because the algorithms have to assign it to something as a color. And it is a bluish light. The bokeh is pleasing there is nothing wrong with the bokeh. However, every lens has its own peculiarities. Some lenses tend to smear the light a bit more than other lenses in these kinds of backlit edge situations. Some lenses are more prone to crisp edge definitions and some are not. This is a highly nuanced thing. Lenses we say are contrasty, are simply lenses that enhance edge definition. There are pros and cons for the design intention. In digital, some algorithms enhance edge definition more than others. As a consequence, we get these little artifacts. There is also another problem we all face, unless this recording device (camera) is on a very stable platform and used with good technique the probability of a bit of camera motion is inevitable. It doesn't take much to ever so slightly smear an edge. These are my thoughts on the problem. Personally, I either live with it or retouch it out.What causes this fringe around the bird...........is it camera shake or something else. THis is a JPG of the un edited RAW file?
