Focusing manually
When it is difficult to get the proper focus in auto focus mode, you can adjust the focus 
manually.
1Set the focus mode switch to MF*.* MF: stands for Manual Focus.
2Turn the focusing ring of the lens to achieve a sharp focus.
 In the case of a subject that can be focused in auto focus mode, the z indicator lights up in the viewfinder 
when the focus is confirmed. When the wide focus frame is used, the center frame is used, and when the 
local focus frame is used, the frame that is selected with the controller is used.
 To obtain steady exposure in manual focus mode, the camera uses the distance information to determine 
the exposure. To improve the precision of the distance information, the camera resets the focal length to 
 (infinity) when the POWER switch is set to ON.

zAbout Histogram
A histogram is the luminance distribution that shows how many 
pixels of a particular brightness exist in the picture. The 
histogram display of this camera shows the brightness on the 
horizontal axis (left side is black, right side is white) and the 
number of pixels on the vertical axis. The exposure 
compensation will change the histogram accordingly. Below is 
an example.
For details on pixels t page 17.
Both ends of the histogram consist only of data of 100% black or white*. Therefore, when the data is 
transferred to a PC later in order to compensate it, it is impossible to restore the area that has been 
blacked/whitened out. Checking the histogram allows you to know the status of the image beforehand.
* To be exact, a color image is expressed with RGB. Thus, the white is equal to R255, G255, B255, and 
the black is equal to R0, G0, B0.

Number of pixels
Use the exposure 
compensation on 
the positive side.Shooting with the 
exposure 
compensation on the 
positive side brightens 
the whole picture, 
making the entire 
histogram shift to the 
bright side (right side). 
If the exposure 
compensation is used 
on the negative side, 
the histogram will 
shift to the other side.
