This is the setup I am using to demonstrate the manual focus of the Fuji X-E2.
When you switch the focus mode selector to M (manual) you can then turn the focus on the lens.
The switch is on the front of the camera as you see here. It would be cool for you to override the Auto Focus and just grab the focus, but that isn't possible for now with the camera. This is something I would love for Fujifilm to add as a feature in the next firmware update.
When you look through the finder or on the back with the LCD screen the view will look like this before you touch the focus or when you push the shutter release half-way down.
When you start to focus the camera will zoom in if you have the MF Assist turned on. I highly recommend using it, because this is better than the traditional DSLR, because you cannot zoom in and see the details to focus this critically.
The MF Assist menu can be displayed by pressing and holding the center of the command dial. When you do you get to choose between two options: Focus Peak Highlight or Digital Split Image.
The Focus Peak Highlight--highlights the high-contrast outlines. Rotate the focus ring until the subject is highlighted. This works for me the best or most of the time. This is what I did to get the image below here.
Digital Split Image: Displays a split, black-and-white image in the center frame. Frame the subject in the split-image area and rotate the focus ring until the trhee parts of the split image are correctly aligned.
Here you can see the Digital Split Image. The clue that you know which one you are using is the Digital Split Image assist is in B&W.
Press the center of the command dial to zoom in on the active focus area during shooting. This works also in AF Mode. It will show you the focus point where ever it is in AF Mode. Just press again to return to full-frame. Focus zoom is not available in focus mode C or when PRE-AF is on.
