[langtitle=es]Sigma 17-70 or Sigma 18-125 HSM?[/langtitle]

I'm a prime (DA15, DA35 ltd and DA70) user that needs a mid range zoom better than kit lens for amateur to professional use, since I'm studing photography and sometimes I do some sporadic works.

My main point is sharpness, I'm not really concerned in vignetting or CA because it can be removed in post process. Both lenses seems to be sharp, but in photozone the 17-70 is not good in extreme corners, wich 18-125 hsm seems to resolve better.

Also, the f stop is not a significant value here, because both lenses are more or less equal, and I'm mainly using a K-x, wich I consider very good in low light.

I'm more interested in 18-125 for two reasons: HSM and the price tag. First, I like to work with small cameras with silent operation to be discret, and second, I can buy these lens with a very good price, around 290 dolars new (255).

In adittion, I think that comes better with my actual equipment.

Anyone can give me a report for these lense??? Do you think that it worth the price, or maybe I should get the 17-70??
