Thank you I appreciate it. I have a pending deal with Kenko 1.4x DGX PRO for a great deal. The sun is to be out by then? Tonight?

I tried my Kenko DGX TelePlus Pro 1.4x tonight after I got home. Unfortunately it never did clear off, so the light was rather dim. I think I got it to lock AF a couple of times out of 15 or so tries; most of the time it just cycled the full focus range from one end to the other without stopping when it got to the focus point, even on fairly high contrast targets. I will try it again when I get some brighter light. The sharpness seemed to hold up fairly well when I focused manually.
