Depth-of-field Scale
The depth-of-field scale indicates the range of
Daoth-of-field 2.3 m ,*3m
subjects which will be in sharp focus on the Fa 50rnm Focused at 3m w
film. This range will vary with the following
factors: The depth-of-field will be deeper the
smaller the lens aperture, the further the
distance of the subject,
andlor the shorter the For example, if the lens is 50mm and the subject
lens focal length. The
depth.of.field will be has been focused at a distance of 3m, with an
shallower the larger the lens aperture, the nearer
F8 aperture, the depth.of-field would be from
the distance of the subject,
and/or the longer approximately 2.3m to 4.3m as indicated on
the lens focal length.
