It was removed from Olympus Trip 35 analog compact camera and adapted to Sony E using generic plastic cap. I was able to focus infinity.
After closing aperture blades form diamond shape so you can get diamonds in the bokeh.
Samples without post-processing. Sony NEX-6.

the 4 blade aperture is new for me in an Olympus lens, quite an unusual looking background
i would like to know, what someone is seeing/thinking who has no idea that this comes from the aperture,
means someone who looks at it "passive" _________________ Thomas

Hi there.
I am trying to adapt the lens from Olympus Trip 35.
It was a pretty easy to remove the lens from the camera, but I have no idea how to control the aperture.
There is that metal rod that is sticking at the back that controls the aperture, and removing it would remove the option for controlling the aperture.
How did you get to control the aperture? |

What does turning the aperture ring on the lens do then? I presume you move that metal rod to the side and it closes the aperture until the setting on the lens is reached, right? |

TeemÃ…Â, you are close, but it's actually the other way around.
By default, the rod is keeping the aperture closed, or at F16.
It's kept like that with a spring.
When you turn the aperture ring, the aperture opens until the rod blocks it.
Now, usually, on more complex lenses, there are multiple components between the rod and the aperture itself, so you can block some of the components in the middle.
But on this lens, the rod directly controls the aperture leafs. You remove the rod, and you lose the aperture control.
I tried to remove the spring that keeps the rod+aperture in the closed position, and somehow keep it open, but had no luck.
That's why i am asking here, if the original poster managed to accomplish a full aperture control.
Not many people on the net that have accomplished this.
They usually just give up and block the aperture fully open. |

Lens was removed WITH part of camera body. Use something like Dremel tool. It solves all the problems then. |
