Top of camera controls
 |
On top of the camera you'll find the power switch surrounding the
shutter release button. Behind this are the mode and exposure compensation
buttons, behind these the Control Panel illumination and FUNC buttons.
Right at the back (overhanging the rear slightly) the command dial.

Command dial - double click?
One annoyance with the command dial was that when changing
settings it ignores the first click (step) of a roll. Example: to change
from ISO 100 to 200 you hold the Flash button and roll the command two
clicks (not one as you would expect). This appears to be by design because
the first click engages the relevant display on the top LCD, the second
and subsequent clicks actually change the setting. The Coolpix 4500 does
not operate this way (one click to change).
FUNC button
Like the 5000 on which it is based the 5700 features
almost the same control structure. The FUNC button can perform a variety
of user programmable functions. In its default mode (user setting) it
allows you to select between the four user setting modes of Auto, 1, 2
and 3. Each of the five possible FUNC functions are described below:
As I commented in my 5000 review it's nice to see the
manufacturers delivering the option to customize at least one camera control.
I found it useful to have FUNC programmed to change White Balance.

Programmed
Auto Exposure

Camera calculates shutter speed and aperture for best possible
exposure, rolling the command dial in this mode allows you to choose
from a "Flexible program" selection of shutter
speeds and apertures which would achieve the same exposure (P* is
displayed in this mode), rolling to the right chooses higher shutter
speed and larger apertures, rolling to the left chooses smaller
apertures and slower shutter speeds, for example a shot in medium
light:
|
|
Shutter |
Aperture |
| P* (turn anti-cw) |
1/500 s |
F4.5 |
| P* (turn anti-cw) |
1/250 s |
F5.0 |
| P |
1/250 s |
F5.6 |
| P* (turn cw) |
1/250 s |
F6.3 |
| P* (turn cw) |
1/125 s |
F7.1 |
Just like previous prosumer Coolpix digital cameras the 5700 only
displays full stop shutter speeds (1/500, 1/250, 1/125 etc) although
checking the EXIF data after the shot shows that it actually has
a much finer gradation of shutter speeds available.

Shutter
Priority

Shutter speed can be selected manually by rolling the command
dial, the camera calculates the correct aperture based on the reading
from the current metering mode. If the selected shutter speed would
lead to an exposure outside of the camera's range the shutter speed
will flash on both displays when the shutter release button is pressed
halfway.
At shutter speeds slower than 1/4s the shutter
speed is displayed in yellow to indicate possible noise in the final
image. (In continuous mode Ultra HS the slowest speed is 1/30s,
in Movie mode the slowest speed is 1/15s). Possible shutter speeds
are:
1/4000, 1/2000, 1/1000, 1/500, 1/250, 1/125, 1/60,
1/30, 1/15, 1/8, 1/4, 1/2, 1, 2, 4, 8 sec *
BULB exposures are only available in Manual exposure mode. As commented
on above the 5700 only ever allows the selection of full stop shutter
speeds, it would have been nice to be given the option of third
stop steps. 1/4000 sec shutter speed is only available when the
aperture is within 1 1/3 steps from maximum aperture.

Aperture
Priority

Aperture can be selected manually by rolling the command dial,
the camera calculates the correct shutter speed based on the reading
from the current metering mode. If the selected aperture would lead
to an exposure outside of the camera's range the aperture will flash
on both displays when the shutter release button is pressed halfway.
Possible apertures are:
Wide: F2.8, F3.2, F3.5, F4.0, F4.5, F5.0, F5.6, F6.3,
F7.1, F8.0
Tele: F4.2, F4.7, F5.3, F5.9, F6.6, F7.4
A much larger range of apertures available at wide
angle because of the relatively small maximum aperture at telephoto.

Manual
Exposure

In manual mode you can select both shutter speed and aperture
(switch between the two by tapping the MODE button). A value display
on the control panel will indicate how much the image would be under
or over exposed with a particular exposure setting as well as an
on-screen exposure meter. Also, available in Manual Exposure mode
are BULB exposures, with this, the shutter will stay open for as
long as the shutter release button is held, up to a maximum of 5
minutes. *
|
* At shutter speeds slower than 1/4 sec the Noise Reduction feature (if
enabled) will take an additional shot after the main shot which it uses
to 'map out' hot pixel noise. Note that when Noise Reduction is enabled
you can not use BSS, Bracketing or Continuous shooting.
