How to capture the sunbeam with Sony H9

[hookeba]

Hi everyone,

I'm a newbie with little knowledge on photography. I came across some nice photos capturing sunbeam at sunrise or sunset. Here's some example:

What is the settings for H9 to capture those exceptional photos ? From what I learned from those photos, I set to F/8 (the smallest f that H9 can deliver), but still can't get nothing like a sunbeam.

Is there any suggestion ?

Thanks in advance.
