Firstly, this is not a tutorial on how to focus using the Fuji X CDAF system. There are enough good tutorials over the Internet for that purpose. (see links below)
So many new users to Fuji cameras are frustrated by the slowness and inaccuracy of the Contrast Detect Auto Focus system. But in truth contrast detect is very accurate when it locks onto the target area. So where does the problem lie? Generally speaking the problem lies with the user and a total misunderstanding of the differences between the CDAF system and the PDAF system used by manufacturers of DSLR cameras. Bye and large the DSLR manufacturers have spoilt their users with amazing technology. For example, both Canon and Nikon, as good as they are, (and I have no complaints about their products), have concentrated on giving the photographer the best technology available to get the very best possible outcome from every possible scenario. All you need to do is to punch in your favourite setting, press the shutter button to achieve focus and hey presto, 99.99% of the time you hit the target on the nail first time, every time (OK, a generalisation maybe). With the Fuji X system you have to stop and think a little bit about what you are doing. The Fuji user needs to tune into the technology at hand and realise that not all camera systems are equal. That doesn't mean that the Fuji system is unworkable, because once you get used to it the whole thing becomes as fast as the blinking of an eye. It becomes instinctive! At the end of the day it's your initial technical input into the photography making process that becomes as important as the camera itself. Unlike Canon and Nikon, where you have almost become a slave to the "perfect " camera system, With Fuji cameras you become a partner with the system. Fuji X system cameras require your input for them to successfully deliver the goodies. I like that idea myself!
Here are a couple of links that might help you with CDAF problems:
