I'm reminded of the little-used Exposure (Exp) slider in world, that is effectively aperture x film speed (ASA) in the fact that it varies the overall amount of light. Film tonal quality is also roughly analogous to exposure's companion slider, Range. Shutter speed is roughly represented by MBlur, which for the default of .5 and a fps of 30 means 1/60th of a second.

Wow... that will be really nice! I was just a little surprised that a sensor size could be inferred, and that the camera “Lens mm” setting actually works in a perfectly physical way -- as long as you know it is a camera with a “crop factor” of 1.353. Even just knowing that, it is possible to convert the focal length of a real lens to the blender camera. There are other things that can be added to the camera, even if they are not used by the renderer. If “Aperture” (f-stop) is there it would be more convenient to use it as input to the Defocus node. It is conceivable that a working DOF node group could be inserted without needing a user to tweak it. And it would be easy to animate f-stop changes. And knowing the f-stop, sensor size, focal length, and focus distance is enough to get near focus distance, far focus distance, and the hyperfocal distance, which would all be useful to the defocus node itself to get better results. Following is a web page that calculates those with javascript: http://www.tawbaware.com/maxlyons/calc.htm Even a seemingly dumb setting like exposure time would be nice to have as it could be used in motion blur calculations Thanks again.
