Hello Minyassa,

Thank you for mentioning this.

I just tried this with build 272. I cannot confirm your findings.

When I choose the Ultra Quality I get the below, with 25 samples, etc.

Fast Preview preset is this, with 2 samples, etc.

Obviously one can discuss the presets and th naming. Should depth of Field be set for ver high quality? That is something one can argue about. However we cannot reproduce the error you mention here.

If the issue persists, I sugest you report it to the Poser support staff.
