Finally, I got my Petzval Lens and I cannot wait to test it, and take it for a ride to shoot! ;D
Here is “What’s in the Box?”
I will try to shoot with it these days, if not, then wait for my Trip to France.. I will definitely take it with me :-)
Happy Shooting, fellas! :)
Searching, studying, and experimenting on how “Swirly Bokeh” (aka Cat’s Eye Effect) form, it’s been two days and now I can conclude what I’ve found.
Swirly Bokeh (Cat’s eye effect); because the Bokeh is making a circular shape.
How Does it Form?
I will list the “recipe” as points, so you can understand easily (of I what I’ve read, and experienced):
- You need Bokeh in the background, so that you’ll be able to see the “Swirl” effect (e.g. Keyboard, Grass, Bokeh of light coming between the leaves)
- If the background is plain, lined, or lacks Bokeh then you’ll never have it (e.g. background is PC Screen, Walls)
- Stick to focus range between 0.6 to 1 (if you go 0.5 or more than 1 you’ll hardly see it; you don’t get so close, and you don’t keep a big distance)
References – How it Forms:
This list contains some of the lenses that can produce that “Swirly Bokeh“: *references below
- Helios 40-2
- Helios 44 F2 (Any Helios 44)
- Helios 44M (I have Helios 44M-4)
- Helios Cyclops 85mm F1.5
- Helios Cyclops 85mm F1.2
- Minolta MC Rokkor PF 50mm F1.7
- Ziess Biotar 75/1.5
- and others… But these are the famous ones, especially (Helios, made in USSR – Zenit cameras)
If you do not want to buy any lens, then try this Hack/Mod: (I didn’t test it)
References – Lenses:
Let me first start with what I’ve found (by experimenting), then I will list some websites that I’ve read about this kind of Bokeh.
(experimenting using Helios 44M-4 mounted on Canon 5D classic)
Focusing at 0.6
Focusing at ~1
Focusing at 0.5 (no Swirl, or hardly noticed)
Now, if you want to learn more I suggest you read these references that I’ve found while searching:
That’s pretty much it, after I had experimented.. I need to sleep..
Happy shooting! :)
