The calibration of my camera is perfect. AF is very fast with sigma 50mm F1.4 EX HSM. In fact the photos seem to be sharper than they were before the IR conversion. I am extremely happy with the work you have done. I am grateful that you returned my camera to me via expedited service. I am impressed that you answered the telephone yourself and spoke directly to me. I wish I had sent my 5D2 Canon to you for repair rather than P****** C******
