Send view to camera

Is there a way to tell the available camera in the scene to grab and use the view in the current 3d window? That would be a great timesaver.

If I’m flying around a scene in a 3d window and I think I’ve found a great POV, I’d like to send that to the camera with a hotkey or a button.

Not sure, but when I’m doing a large landscape, I usually render from fly mode. go to camera view>shift f> LMB to go forward> MMB to go back> space bar to stop> cursor controls direction. When you find your angle just hit space bar and render same way as always.
