Is there any alt 28mm or 24mm lens that is sharp from corner to corner
at least at f 8 or 11 , and not to expensive?
And if possible no moustache distortion.

Of those that I have that are not terribly expensive, I would say that the Olympus OM 28mm f/2.8 qualify. I've heard that the f/3.5 version is rather sharp as well. If you can go a bit wider, the OM 21mm f/3.5 is more or less legendary, but also more expensive.

I used to have the Nikkor 28mm f/2.0 AiS as well, and found it to be very sharp all over when stopped down, but I liked the above mention Zuiko more.

Best bet is probably the SMC Pentax 28/3.5. It has slightly lower contrast than the Contax 28/2.8, but higher resolution and lower price. The SMC Pentax 28/2 (same as Contax 28/2) is the best I've owned, but it's probably too expensive.

I recently acquired a SMC Pentax 24/3.5, but haven't yet had a chance to try it out. The Oly 24/2.8 is pretty good, but not as good as modern L-series zooms.

You did not mention what body but for the Sony A7 series and for slow 28mm lens shooting landscapes I settled on the short lived SMC K Pentax 28/3.5 (make sure its the K not M - You can find the measured resolution difference between these lens here). I really like this lens! The close 2nd was the Oly 28/3.5. I found the CYZ 28/2.8 Distagon is lovely everywhere but deep corners.

yes for Sony A7

i just found this list, which is almost the same:
http://www.takinami.com/yoshihiko/photo/lens_test/procedure.html
so i will search for the penatx K 28mm and 24mm seems also quite good ...

I had the Oly 28/3.5 in Canon 5D days, but was most impressed because of its size and price.

Oly 24/2.8 has a great reputation. I have a Canon FD 24/2.8 that I got on the cheap that is also very good, especially stopped down.

My apologies to your lens. I haven't had the pleasure of owning one.

CV 28/2 M-lens. Sharp from corner to corner in middle aperture range with very low vignetting for a reasonable price.

Anyone got a good website for a primer on Pentax lenses to learn what all the M's and K's and FA's mean? That's a set I know nothing about and I feel left out

For almost nothing, the Olympus 28/3.5 is a very good performer -- nice and sharp, and really minimal distortion. It's usable wide open and gets excellent at f/8.

For wider, the Olympus 24/2.8 is a really nice lens. Corners are a bit soft wide open, but by f/8 you're good to go. It has more distortion than the 28/3.5 (barrel), but it's a simple form and cleans up easily.

The Olympus 21/3.5 is also very decent. It's not as sharp as the 24/2.8, but it has less distortion and is a reliable performer.

I think the no moustache distortion part will be tricky for a 24mm

Both the FD and OM 2.8/24 have noticeable mustache distortion. Check my reviews for samples:

OM 24/2.8 has noticeable mustache distortion? Perhaps it's more pronounced on full frame, and that's something I should have qualified above. I'm using my OMs on an APS-C sensor. I see barrel distortion in the first brick wall image, with maybe a hint of a mustache. It's definitely stronger than the OM 21/3.5, I'll grant that, but it cleans up well in Lightroom with manual settings (see second brick wall image), and that's the acid test for me.

Zeiss ZF 25/2.8, high contrast, sharp corner to corner at 5.6 and cheap if you get the older ZF.1 version

the olympus OMs have pretty weak corners imo. the contax g 28/2.8 + 1.5m pcx filter will destroy most of the lenses mentioned at any aperture. these days it goes for around $350 +$100 for the pcx filter. the zm 25/2.8 is also awesome with the pcx filter, but more expensive.

The Samyng 24mm f1.4 is pretty sharp corner to corner, has great sunstars, and no moustache distortion. It's big, but a great performer for the price

I got the Yashica 28/2.8 C/Y, DSB I think. Seems to have very little distortion:
