I believe that Canon removed the aperture ring from their lenses as a
cost savings and have managed to convince photographers that this is
more modern and that the lack of this feature is in fact a feature.
While having manual control of the aperture on a very long lens on the
body of the camera may be desirable, as the aperture ring could be of
necessity in an awkward place, it only makes sense to put aperture
control on a shortish lens and divide up the shooting controls a bit
more equally between both hands. At least Pentax and Nikon used to give
you the choice of how you wanted to work. Now it's left to Panasonic
and Samsung to allow that.

Well... now I believe that D-FA and DA no longer have a meaning and
they are used randomly.

Actually the latest DFA 100mm macro that's weather resistant doesn't
have an aperture ring, either that or they've done a damned good job
camouflaging it.

So far, all D-FA lenses have an aperture ring, while it seems some DA
lenses cover 24x36 format (how well, I don't know).
So I have the feeling that now DA just means 'without an aperture
ring' and D-FA means 'with an aperture ring', irrespectively of the
lens coverage.

Not a lot of thoughts really. However if Pentax was really going to
announce a FF K mount camera wouldn't the latest lens, the DA 50 f1.8
which is pretty much one of their 50mm designs going back to oh, I don't
know the middle of the 20th century, and probably covers 24x36mm frames
admirably, be designated a DFA lens? True it doesn't have an aperture
ring, but it wouldn't be the first DFA lens to be released without one.
In the event of a FF camera probably wiith a list price between $2500
and $3500 it wouldn't cannibalize many sales of the FA 50 f1.4 lens with
that camera as the lens cost difference would be a fraction of the total
package price. So either a.) Pentax marketing has their collective
heads where the sun don't shine, or b.) there really isn't a FF camera
that close in the pipeline. I'll not take any bets either way, since
this is not necessarily an either or proposition.
