Depth of field works incorrectly in KeyShot 6.2

[Ricchezza]

Hey guys! There seems to be an issue with depth of field in keyshot 6.2. Check the images i attach to the post. As you can see when f-stop number is low - you cant see a thing in a viewport. Only when it reaches 200-256 (btw 256 is a limit, you cant go higher) the image starts to appear normally. But still it is not the same with KS5. And it is bad because i no longer can add just a slight blur on the background of an image. Even at the 256 f-stop value the background is heavily blurred. It is not a hardware problem cause its the same on two of my computers. Any suggestions? Thanks to u all)

Can you share the scene?

Have you tried changing the scene units ? Usually that helps when the parameters get messed up.
