Thank you all for your feedbacks! I bought the Pentax 12-24 f4 one... and already in love with the lens :D I think I will have to buy a new cam for the other lenses because I am not willing to take it off from the camera! :D :D :D Cheers, .timber -- PDML Pentax-Discuss Mail List PDML@pdml.net

The Sigma's a good lens for the money, I've had no problems with flare, the front element is not that large in comparison to some. I couldn't put it down when I first got it. I'm sure the Pentax is also a very fine lens. Sample image from last summer:
