Today I have been experimenting with Depth of Field to which I had intended to apply to my shot. It had varying results which are shown bellow.

Applying the mia_lens to the camera.
Tweaking the setting allowed me to focus on the Bee but left the background looking a little to blured.
A few more tweaks made the background looks a little nicer.
Zooming out to check focus showed a problem. There was no focus on the closest object.
Tweaking and experimenting with the settings I was unable to really allow the camera to focus on the object closest. I believe it is due to the distance to the objects and the camera.
Although I was unable to master the depth of field, I did get a glimpse of what it can do and the problems that follow. It was somewhat successful however and this could probably be sorted with a technical conversation at some point.
