# The Setup
I started out using a tripod, with the same ISO and exposure compensation using
a [**Minolta 50mm f1/7**](https://en.wikipedia.org/wiki/Minolta_AF_50mm_f/1.7)
lens. Starting at *f/1.7* I worked my way up at reasonable steps to *f/4.0*. My
aim was to compare the differences. See the shots below. The target couch
cushion was set up roughly a meter from the bottom center of the tripod.
# Depth-of-Field
There may be something to be said about maintaining the best DoF
(*Depth-of-field*). However, using [PhotoPills DoF Calculator]
(https://www.photopills.com/calculators/dof) proves just how **wild**, using a
50mm lens, an aperture of *f/1.7* is. Shooting a target of *2 meters* results in
a depth-of-field of **16 centimeters** -- that's a very narrow range! Bumping up
the aperture value to *f/2.8* provides a much more reasonable *27 centimeters*,
though still a bit narrow. Either way this allays any fears I had of losing out
on that sweet, *sweet* [bokeh](https://en.wikipedia.org/wiki/Bokeh), though the
photos themselves illustrate that not a significant amount of Depth-of-Field is
lost at that target distance of 1 meter.

The biggest difference can be seen between the *f/1.7* and *f/4.0* shots. Note
