Want to make a pick up and focus on item system

Hey guys, I would like to set up a pick up system, but I don’t want it to disappear or go to inventory. Want like a tomb raider or Allison road type of system. I don’t know where to start so if I could get some help or be referred to a tutorial that would be great. I’ve looked through a lot of videos and none really answer my question. I would like the camera to focus on just the item and have the background blurred during view. Also make it rotatable in view mode. With the same button enabling pick up and view and that same button putting it back down. Thanks for any replies. I was able to create a zoom effect on the main camera but that’s about all I was able to pull off.
