Cooke-Kinic 25mm f/1.5.
The Vietnam Women's Memorial, Washington DC:
I love swirly bokeh. The Cooke Kinic looks like a fun and interesting lens!
I like that kind if bokeh too.
Wow that's dizzying!
But count me in as another swirly fan. I've been getting rid of most of my legacy lenses since I don't like to manual focus, but I think I'll be keeping my Pentax/Cosmicar 25mm for the swirls (although it's not as pronounced as your lens!)
Need. Some. Dramamine.
Really works with that subject though I think.
I think that would be called a special use lens....I love a good swirl, too.
+1, it really is a part of the composition, connecting the heads with some sort of dreamy circle.
Is spiral bokeh directional or static?
Love these 16mm lenses.
What a powerful image amplified by the swirl bokeh. Any ideas what caused the diagonal striping on the torso? I view the swirling as clockwise. Attached is an image I shot yesterday to explore bokeh of various lenses. I read the spiral bokeh from the Taylor Hobson 1"/1.9 as counter clockwise. Is there a member who understand the optics? Is spiral bokeh directional or static and if so why?
I anxiously awaiting the return of my Kodak Cine Ektar 1"/f1.4 from a CLA. Taking a bit longer than expected or perhaps I'm just too eager.

You're pulling our leg here - that swirl isn't caused by the lens. I've been to that memorial, and that's exactly how it looks for real! Or was it the drugs I was on....?
As a general rule I don't like the swirl bokeh but when used right I do. The example of the women's memorial works is one that does indeed look nice..
the "bokeh" is a comatic aberration. These lens were meant for even smaller frames, so the center image would be only recorded leaving the comatic area mostly out of frame. The reason they were used is they bring the area that is in focus sharper than other lens designs, all things are a trade off in photography I suppose. To manipulate the comatic area play with your depth of field, and background lighting. The diagnal stripe is common of a lens with no coating. Wiki optical abberations and you'll find some good sources for more info on coma and other odd lens properties it gets interesting.
Jim, thanks for your reply. I did visit and over viewed the plethora of information and an begining to understand the interrelationships of many lens related terms I've known.
It's lens flare.
Thank you. That's amazing, so uniform over such a wide area.
