a77m2 macro lens?

I am looking for a good macro lens for my a77m2 and don't know what to get...

Also, is there a good movie setting for the camera for green screen footage?
I'm really kinda new to photography and i really don't understand all the settings and stuff...

here's some of the stuff i have taken so far (the bee photos are not mine - those are re-posts... I want to take macro photos like those):
