Camera DOF problems with object edges on renders

[Nightmare0wl1]

Hi, lately I have been experimenting with the DOF of cameras in Unreal Engine 5.5 and I found a problem that I’m not able to fix. In the bottom right corner of the image you will be able to see the edge of the lamp on top of the DOF

(0.1 Aperture) it looks like some kind of ghosting on the edges that repeats in other cases

in this image you can see the edge of the tip of the fingers even when affected by motion blur.

This only happens with renders.

This is how the scene looks on the editor.

Here are some more references:

No DOF

0.3 Aperture

1 Aperture

It is hard to see but with 0.3 Aperture you can see the dark edge starting to take shape.

I have seen many people affected by this problem but with translucent objects (there are no translucent materials here), I have tried those solutions but nothing works. It doesn’t seem to be dof quality or anti-aliasing, tried that too. Also there is no post process going on outside of the camera at the moment.

The improvised solution I have found for this is setting the aperture to 0.11 instead of 0.1 for the lamp edges. And for the motion blur finger problem using 1 Spatial sample count and 32 Temporal sample count for the antialiasing in the render was enough to smooth it out.
