ah yes..the addiction of the 10mm has already taken over! has barely left my camera body since i got it.
was actually looking at the sony 11-18 at the same time as the sigma..have been wondering if i should have gone that route but your tale has made me think i made the right choice and also saved a few dollars
thanks for sharing.
did get a get a CPL with the lens but am still waiting for the ND to arrive so hopefully it wont be too much to deal with the vignetting issues. and also hope 77mm lens caps come cheap. appreciate the heads up.
