Camera Weapon and Suit Zoom

[Sometimes]

I am curious about the Camera weapon and the Suit Zoom (Middle Mouse 3). I remember back in GM 8 and before, I was able to select the camera weapon and still be able to zoom with the "Suit Zoom", but in 10 I can't. I figured maybe if I just "cl_drawhud 0" and just zoom from the default construction view but this doesn't remove things such as lamps, cameras, etc..

So, is there a console command or something I can attempt to get "Suit Zoom" while I'm using the Camera weapon?
Or, maybe a command that could fake this within the default view, like "cl_drawhud 0" but would also remove props like the camera and lamps and such?

Sorry in advance if I missed a post that address this..

Thanks,
Sometimes
