I am considering getting something wider to complement my Sigma 17-70 mm on the KP. I have been looking at the HD 11-18 mm and the Samyang 10 mm (I don't consider the Pentax 12-24 mm an option as it is not much cheaper than the 11-18 mm which I guess is superior).
What would be your choice and why? I notice that a couple of users complain that the Samyang is difficult to focus. Any other options?
