Great explanation of diamond shaped "UFO's"

well some...

Please click on the text to be taken to the full thread.
Unfortunately, almost all of those were shot with Sony Brand cameras, and even on Sonys website, it explains the type of aperture blades they use, and they are diamond shaped, and therefore unfocused specular highlights (such as what is in the videos) are also diamond shaped.

You can even create the effect yourself in a very simple manner, so that its easier to understand how an aperture blade shape will and does create this split diamond looking artifact.

But the appearance of that shape alone is not enough to constitute a 'good' ufo video, even if it is actually a TAPE of a ufo. This manufaturing fact just means that its more likely mundane objects that are being fimed, with this lensing artifact present.

The diamond shaped pattern people are seeing in recent videos are not evidence of craft.
Although it is possible they ARE filming something unusual for sure..the diamnond pattern itself is not evidence of that..

It comes from the blades that form the camera aperture itself
(the Focusing hole to the sensor)

The Effect is called Bokeh. Its Japanese for Fuzziness..

Cameras with more blades will render this effect as a soft circle.
Consumer level video cameras will render it as a triangle, as they generally have two Blades..Hence the diamond shape.
This is what occurs when the focusing mechanism tries to lock onto a point of light..
Ie Christmas lights, plane lights, and planets.

The Following is from SONYS site itself as proof of what im saying..
so Dont bash me for using facts to back up what im telling you..

Conventional compact camera lenses feature a 2-blade iris diaphragm (aperture iris) that produces diamond-shaped bokeh at partially open aperture. The “G Lens”, on the other hand, features a nearly round 6-blade iris diaphragm that creates beautiful round bokeh. At large focal lengths that produce a shallow depth of field — especially in “G Lens” models featuring optical 20x zoom — the amount of bokeh in the foreground and background can be controlled through fine adjustment of the aperture.

Here are several decidedly NON alien subject matters, exhibiting a diamond shaped Bokeh pattern: These are forks.
