How to get exact camera view? I'm currently a beginner when it comes to 3D modelling but doing okay so far. I'm struggling a bit when it comes to the final renders of my scene, specifically on the camera view I want. Sometimes its to zoomed in and sometimes to zoomed out that it's gone out of the environment of the blender. I realized the settings for the camera on blender are for actual cameras / photography and I'm no expert on that too. A tip on how to control them precisely would be nice. Thank you.
Go into camera view (Numpad 0) and use Lock Camera to View.

Then, navigate as you would normally do in the 3d viewport using the mouse or the keyboard.
Numpad 4 and Numpad 6 will rotate left right.
Numpad 8 and Numpad 2 will rotate up and down
Numpad + and Numpad - willmove the camera forward and back

Or Use Fly/Walk mode:
