The external renderer doesn't have depth of field options as far as I'm aware. The source for 0.99b6 is from early 2013, which may be too old for the feature to exist. Another potential problem is using an orthographic projection, for which the depth of field parameter was only recently enabled. If the Internal renderer is giving problems, just set your aperture values via the command line if you've got something close by testing with OptiX on a smaller resolution (display dof_fnumber), as I agree that clicking on the values a bunch of times is not a good use of anyone's time.

Hi all!

I sent this mail earlier, but I think it got buried in everyone's
holidays. Does anyone who's just come back from their well-earned
holidays and conferences have any insights?
