I'm looking for a small/cheap 35mm equivalent walk-around lens for my d7k. A year ago or so I had the unluck to test the 2.8d version and my copy had massive problems with build quality, sharpness and focusing. I'm thinking that it was a dud, because the performance was a million times worse than how it looks on photozone and lenstip. I don't want a lens that's perfect when pixel peeping. I don't mind much if the CA is a bit stronger than average. I just want good performance when stopped down to f4-8. (good performance = it can be shown off on a fullHD TV screen) Focusing is not a problem, I have a k3 focusing screen.. :-)
Probably I can get one with minor front element scraches for about 150-200$ on ebay.
