In real life - those objects will be totally blurred out with Sigma Art 1.8. with 0.5 meter distance from each other. So imagine how it should be with 0.5, but there is no glass in real life to compare. Also I used sensor size and focal length 36mm for octane camera, my camera have super 16 mm with focal length 18mm, with will make no big difference in any case. And ether way if I adjust Octane camera to my cam settings - will not match.
Unless I am misunderstanding your setup, I don't seem to have issues with dof... Do these look accurate to you? In this example, the White, Gray, and Black Spheres (1.5in Diameter) are each 10in apart.

If this looks correct to you - Here is a sample scene with a bunch of spheres.

Your setup is ok, but we are talking about something else.
What the image will look like in real life when the aperture is 0.5.
With 0.95 aperture objects already totally blurred like this. And if you set you camera to 0,5 f-stop you get super blurred image with one or two petal of flower in focus.
Therefore, what is designated in octane as an а-stop 0.5 is not correct and has nothing to do with real optics.
