Final update:

I returned the lens to KEH, and was able to purchase another one from a forum member here a few days ago. The difference was night & day. The new lens looks sharp, and crisp, and contrasty. There was definitely something wrong with the one I had purchased from KEH. I performed the tests on the new lens with the same body & under the same lighting conditions ect.. to make sure everything was the same. I imagine the old one will be back up for sale on their site soon, if it isn't already. FYI the serial number is: 3005013 so if someone here buys that one, I'd be very interested to hear what their findings were. The 2 images below were taken with the new lens wide open. The first one if just the lens on a K-5 ii, and the second image is with the 1.7x AFA attached.

Thanks everyone for your advice & help!

George
