K5 Back Focus issue solved
Jun 10, 2012

So,

I've been having some back-focusing issues with My K5 and Sigma 180mm F3.5 lens. This was more pronounced with very small subjects. The AF Fine adjustment setting on the K5 can be adjusted between -10/+10 but that was not enough. So I put the camera in Debug mode via my PC and I did a global adjustment change for the max and min allowed....something like -100/+100. That did the trick. Look at these before and after pics. Good enough for me.
