Please translate an article to use with Pentax Kx

The article is basically talking about "Back button focusing" and "AF.C" mode.

I just recently tried this with my K-x, it works pretty well for me. The thumb will feel odd at first, but you will get used to it after a while.

For K-x, back button focusing uses AF/AE-L button, go to Menu, there is a setting called "10. AF/AE-L Button", choose "2 Enable AF2", this will disable the shutter focusing, and use AF/AE-L to lock focus. (you will lose AE-L function with this setting)

To use AF.C, press INFO button. Beware that if your DA lens has Quick-Shift, you need AF.S.

Hope this helps.
Bill.
