Particles flares not being affected by camera DOF

all light and elements in the background are being blurred correctly by the camera DOF as you can see but the particles lightflares are not being affected by the DOF which is a bit weird.
Any ideas why is this happening and how to fix it?

bump! I really cant seem to find a solution

There isn’t. Particles do not write depth, and therefore won’t receive proper depth of field.
There is a setting on material, called Render after DOF. If you disable it, particles will receive same DOF as the surface behind them.

One of the ways to deal with it would be just faking DOF in particle material itself.

Where can I find the “render after DOF” option in the material exactly?

Is is the same reason why particles are not affected by camera bloom?
