How do I get the log files on my Optima Smart 220? I want to access the log files of my tablet (Optima Smart 220, running 4.1.1 Jelly Bean).

Also, how do I root this device so I can get the log files?
You don't need root to access log files.

One option is to use the adb tool from the Android SDK. But it's a huge download.

Another option is to use a tool like LogShark.
