That’s the case with a bird on flat open ground with short grass, but what if it’s perched amongst branches or has long grass or bushes behind it


I found this topic, as I my website was mentioned earlier. It seems to be neverending debate again. Could you please tell me, if you feel anything wrong with the background rendering or bokeh or whatever it is on the following pictures? I chose those as example of more natural environment than short-cutted grass. Btw. those pictures are not mine. Thanks for your opinion.


three out of the four look quite OK to me. Their backgrounds don't distract my eye from the subject.

The top right image however has a disturbing/distracting rendering of the background. The grass, sticks, etc are not rendered with soft edges, instead the edges are rendered as high contrast lines that appear to be 'multiples' of the actual edge. This effect has been called "nissin bokeh" by some and is usually mentioned or discussed as an undesirable quality.


Thanks. To me, NONE of this background is ok (and not saying anything about purple owl). But as mentioned above, it is not fault of the lens, it is just wrong angle of view with little attention to the background. ALL of those pictures were taken with Sony FE 600mm/4.
