How to make Fisheye renders in Blender? Set a wide angle camera

Fisheye lenses, you probably have heard of it once or more before, it's that wide angle lense that gives a spherical feeling to the image, let's find out how you can apply that to your renders in blender.

You can play with the Lens Value which is 15.00 in this case, until the camera fits the scene, because if it set to a really low value it will show as a sphere, but after increasing it, it will cover the whole scene inside the camera. Something to mention as well, you can't see the result until you switch to render mode or by clicking the shortcut Shift + Z, you can then move your camera to suit your taste.
