Maximizing Render Field of View in Interior Scene I'm new to Blender and love most things about it, but the camera is hard to work with, especially in tightly enclosed interior settings.

When I've positioned the camera where I want it and bring up the camera view (Ctrl + Alt + 0), it only captures a small portion (maybe 50 percent) of what's in the viewport. When I try resizing the window, it doesn't go all the way to the edges, so the only way to get everything in the shot is to zoom out... but that's often not an option with an interior scene, because I end up going through a wall. Changing the focal length distorts the image.

Are there any other options to solve this problem? In most other 3d apps I've used, you can simply resize the render window to fit what you're seeing, and even go beyond the field of view. Is there anything like this in Blender? Are there some camera constraints I can turn off for this?
You can change the sensor size in the camera settings. Or you can change the focal length. But what about distortion for a wide lens - it's physics, you cannot cheat it. If you want, you can use orthographic, or panoramic camera (the latter seems to work in cycles only). If you want an impossible camera shot, you also can make some of your walls to be transparent for camera rays from outside, and make the shot through the wall with the lens focal length you want.
