Right and right. Both the Nikon 10.5 fisheye and the 12-24/4 are
great lenses. There is a bit of barrel distortion on the fisheye
though. The 10.5 is frequently used as an ultra wide angle with the
conversin in Nikon Capture. Klaus Schroiff did a pretty fair test of
the 12-24/4 here:

Is there an 18mm lens that is free of barrel distortion? As you say
it is all correctable these days.
