When focusing on a certain subject, there is an 
area both in front and behind the subject that can 
be held in focus. This range is called the depth of 
field. When the range is wide it is a deep depth of 
field and when the range is narrow it is a shallow 
depth of field. Depth of field has the following 
characteristics.  
(1) The higher the F value the deeper the depth of 

field, the lower the F value the shallower the 
depth of field.   

(2) At the same F value, the shorter the focal 

length of the lens, the deeper the depth of field, 
and likewise, the longer the focal length of the 
lens, the shallower the depth of field.   

(3) The farther the distance from the subject, the 

deeper the depth of field and the shorter the 
distance from the subject, the shallower the 
depth of field.   

(4) From the position at which the subject is in 

focus, the depth of field is shallower to the rear 
and deeper to the front.

Depth of Field Checking   
The range for depth of field can be read by the 
graduations for depth of field that are on every lens. 
The figures rowed on both sides of the lens 
range/F index are the depth of field graduations. 
The depth of field graduations are written in 
relation to the range graduations so that the depth 
range can generally be read from the distance 
graduations.
