Hi David,<br>It's worth noting that the F-number is a value dependent on both the aperture of the lens and the focal length, so as you zoom the lens, the f-number becomes higher. (F number = focal length / aperture). So it's actually a ratio. That said, it would be nice to have the option to choose to use f-stops, but the value would have to update as you zoomed in/out.<br>

Simpler solution to close by mistake or crash is not saving a flat png<br>
but a package with the samples data like luxrender does, so you can<br>
simply resume your render like nothing happened. This idea is already<br>
in the todo :)<br>
