Anyone compared Sigma Super-Wide II (MF or AF) with K24/A24?

I was reading in another forum that Sigma is sharp across the frame while Pentax has soft corners. Not much concrete info though.

Any idea?

I've been very happy with the f/2.8 Pentax lenses.
Although they are indeed not as sharp in the corners as in the center,
their flare resistance and excellent color rendering,
along with their relatively small size,
make them very useful lenses.

Was that the old "World Cup" comparison on Canon?
The K24 there was used on an adapter,
which may have compromised the quality.

I had a Pentax K 24mm 3.5 but I did not keep it due to sharpness falloff towards the edges. I have the Sigma 24mm 2.8 MF and am more than happy with it. Flare is not a problem if you use a hood.
