Wim, isn't it funny that for the longest time, 12mm of the Sigma 12-24 (or the Voigtländer prime) was the absolute widest one could get without defishing, and then all of a sudden there's a wealth of options all the way down to 9mm.
By the way, Lenstip has reviewed the 9mm recently. Totally not perfect (CA, huge distortion, astigmatism, flare, strong vignetting...) but since it's the only game in town for 9mm, it's acceptable, especially given that they found it to be pretty sharp.
