Diopter Compensation
Diopter compensation function enables
dioptric adjustment of the viewfinder to
suit individual users. This makes the
viewfinder image easier to see, facilitating
image composition setting.
Mirror Lock-Up
The Mirror Lock-up function opens the
shutter after vibration caused by flipping
the mirror up stops, to ensure image
sharpness. This function is especially use-
ful when using a super-long telephoto lens
to take scenic shots.
Use the RS-21 Remote
Control with the Mirror
Lock-up function to
ensure blur-free pictures,
unaffected by mirror
impact. The remote also
lets you operate the shut-
ter away from the camera.
This is ideal for taking
self-portraits, family pic-
tures, etc. (The RS-21 has
three channels to prevent
interference with other SA cameras being
operated by remote control nearby.)
Exposure Control
When shooting in tricky lighting situations
such as high-contrast scenes, snowy
landscapes, or dark shadows, you can use
exposure compensation or bracketing to
ensure you get the exposure that best
renders the scene. With the SA-7 and
SA-9D, exposure can be compensated up
to ±3 EV in 0.5 increments.
In addition, the Auto Bracket function
allows continuous shooting of images at
three different exposure levels (standard,
under-and over-exposure).
Multiple exposure function allows the
creation of dazzling, surreal effects by
recording up to nine images on a single
frame of film.
The Command Dial is located near the
shutter button. The Command Dial allows
the setting of various functions when used
in combination with other dials or function
buttons. It minimizes operating errors and
ensures precise control.
The Drive dial is used for fine adjustment
when taking pictures. Simply turning the
dial easily sets both the Mirror Lock-up
function and high-speed film advance. The
Drive dial is designed to simplify operation
for users.
The dial for adjusting shutter speed and the
selector for setting the exposure mode are
located near one another. Designed with
users in mind, these controls provide easy,
reliable control of camera operations.
The viewfinder displays a variety of infor-
mation in easy-to-read characters and color,
to assist photographers. You don’t have to
look away to obtain the necessary informa-
tion. When used with the diopter compen-
sation function, the viewfinder ensures the
optimum diopter setting for every user.
The LCD panel on top of the cameras
display a variety of shooting information.
These include low-battery warning, flash
mode, metering mode, film counter, etc.
Equipped with two- and ten-second self-
timer modes. The 10-second self-timer
mode is suitable for family pictures. The
2-second timer can be used instead of a
cable release shutter mechanism, to help
minize vibration.
