wide again

After lots of dithering, I have been to Park Cameras again today, coming back with the Sigma 10-20, must be careful not to throw this one in a river! So far so good, it seems sharper than I expected, a bit soft on the right hand side wide open, but fine by f5.6 or f8. Not too much vignetting with my massive old linear polariser either. Bring on the wide expanses of Scotland!
