Render image too far away (Maya)

So as I am watching tutorials, there have been a few cases where the instructor showed a rendered version of the project being worked on. When I pulled up my own render, it appears that the object is a lot further away from the camera and seems small in the render box. So you cannot really see all the details due to how far it is. And when I zoom, it just becomes pixelated.

How can I fix this so it looks more like what I saw on the videos? Up a lot more closer and clear shot.

which maya version and render engine do you use?
maybe this could help:
