When the camera comes to an obsticle it zooms im and then out when it has passed it. Is there and addon that makes the camera stay in place so it doesn’t zoom in?
Good question. Wows camera system is very archaic.
What, so it’s blocked by the terrain or whatever and all you can see is the inside of a wall?
What do you mean?
there is no such addon. I’m pretty sure the camera functions aren’t available to addon developers.
Damn, that sucks 
Just how assets and texture mapping works, this can’t happen with current technology.
Blizzard intentionally took away those options including on classic. It was a change that was not needed and made the game worse imo.
If just looking for left-right-up-down, there is. I use SynCamera. I don’t think there is one to lock the camera distance, because that would amount to a camera exploit, looking through obstacles and whatnot.
