Hyperfocus (or manual
focus) mode. For anyone that venture into manual focus mode of
Minilux, the straightforward approach is to set the manual focus
setting to an approximate subject distance.
If you happen to bring the
DOF table like below, you could also take your time and choose the
range of clarity by using aperture-priority mode plus manual
focus.
However, if the far end of
subject's DOF is infinite, there is a trick of estimating near end
of the DOF without referring to the table. (I first learned about it
from Mr. Richard Saylor at this site).
For example, referring to
the following Minilux's photo, if you select the aperture (say f16) and align the green AF dot to the
aperture, the DOF is about infinity to half of the "green P" indicates
(3.5 meter/2) of 1.75m. More precisely, referring to the green box
of DOF table below, the DOF range is 1.63m.
As another example, should
you choose f8 and align AF dot to 8, the green P dot indicate 7m. So
the DOF is about 3.5m to infinite. Referring DOF table
indicates 3.23m-infinite (the red box).
This easy estimation
method has limitations: (1) Doesn't work for f4 and f2.4 and (2) It
is not a complete scale of DOF setting like a professional camera
and only works if one end is infinite.
