Bob,
I have a Carl Zeiss Jena 20/2.8, with the same 67mm filter size as the 
Pentax 20/2.8. For about $13, I bought a pretty black Adorama-brand metal 
circular wide-angle hood from Adorama. It's not petite. I plan to fit it 
with a Schneider 115mm press-on hood from B&H ($20)  or a stretchable 
Op/Tech Hood Hat, size large (4.5 inches), $9.25 from Adorama.

I just bought a filter for the lens: Heliopan multicoated UV Slim (about 
4mm), the slimmest filter that can accept threaded hoods.

Actually, Bob, I wasn't specifically referring to the A 20/2.8's
jen-you-wine aw-fish-ill hood, but to the lens itself (which has
that flaring front end to cleverly prevent vignetting when adding a
filter or a hood).

As for the "official" A 20/2.8 hood (I think it's a MH-RB67), it's
shaped like a big pie plate with a hole in the middle, and is pretty
useless, in my opinion.  (Although, mounted on a pole and aimed
toward the equator, it picks up 249 TV channels...)  It does come in
a nice leatherette case, though - .

Anyone got one? >>

Yes Peter, and the M20/4 is much stealthier than the K20/4 which is a big old thing...

IMO, there is.  It's the one for the Super-Tak 20/4.5.  You'll need a
step-up ring for it, but it'll work great - in fact, even better on the
A20/2.8 than on the ST and K 20 mm lenses, which also required a step
ring, but from 58mm to 77mm.  The hood comes with such a step ring, and
all you'd have to do is replace it with the appropriate sized ring for
the A20/2.8.  Stealth it ain't!

The A 20/2.8 is my most often used wide angle lens.  Both the A
16/2.8 Fisheye and the A 15/3.5 are all too often likely to be left
at home (unless I know in advance that one or the other might be
used), but the 20/2.8 is likely to be with me in my kit bag.  (I'm
not sure that the A 20/2.8 quite qualifies as a "stealth wide
angle", what with its flaring filter thread mounting, but it
certainly is a ~portable~ wide angle.)

Nice one, Cyril. Another stealth wide angle. 

Natch, we will have a couple of 20mm A for stock on the next delivery.

Yes, but it is not that good wide open and also display a warm color cast. 
Stopped down it's a very good lens and it's true that it is exceptionally 
flare resistant for such a wide lens.

This lens seems to be extremely flare resistant.. compared to

Has anyone tried it with astrophoto / aurora (Pål ??) ?
