Contemporary optical advance is obvious: we get previously unthinkably wide coverage and good-excellent linear rendition as well. The Laowa 9mm f/5.6 is amazingly rectilinear given its unbelievable 135 degrees angle of view (diagonally) on the FX frame. Horizontally it still delivers a whopping 125 degrees view. Image quality can be very high, but the inevitable "price" to pay is elevated light fall-off towards the corners of the frame.

It is safe to say these über-ultra-wide views clash violently with human vision impressions and therefore, rarely actually confer a visually useful advantage to the image, apart from the shock effect. We simply do not perceive our environment in a similar manner. Thus the impressions are alienated and strange. For landscapes they are next to useless if the intention is "showing all". They indeed do, but concomitantly everything is reduced to tiny objects and the sheer greatness of a landscape is lost. You can easily shrink even the mighty Mount Everest to a tiny protrusion on the horizon

Yet despite these objections, playing with challenges is always desirable.

who painted them? or is your D200 sensor loosing control? Have never seen pidgeon cacadoes before 
anyhow I like the picture, beeing envy, that in my age holding a white feather with the tail while dancing around  will be a challenge

Each pigeon fancier has their own colors and paints their champions for competition. The male pigeons relentlessly pursue the females; they are bred and trained for this purpose.

Near my house, they hold pigeon races. They paint the males different colors so they can be distinguished. The pigeons chase a female with a white feather in her tail; the one that gets closest to her scores points.
