Key Components of the D7100
You use the exterior controls of the D7100 to access features that you change often.
Being a higher-end model than the D3200 and D5100 series, the D7100 offers a lot
more buttons and dials to allow you to change your settings more quickly, which is a
good thing. On the other hand, the D7100 has fewer buttons than the professional-
grade cameras, so a lot of the buttons perform double or even triple duty, depending
on what mode the camera is in.
The good news is that you can customize a number of buttons so that you can control
the settings that you need to access most often.
Top of the camera
A lot of important buttons are on the top of the D7100. This makes it easier to fi nd
them, especially when you have your eye to the viewfi nder. This is where you fi nd the
dials to change the shooting modes, as well as the all-important shutter-release but-
ton and the relatively new Movie record button.
Shutter-release button. In my opinion, this is the most important button on the
▶
camera. Pressing this button halfway activates the camera's autofocus and light
meter. Fully depressing this button releases the shutter, and a photograph is
taken. When the camera has been idle and has "gone to sleep," lightly pressing
the shutter-release button wakes it up. When the image review is on, lightly
pressing the shutter-release button turns off the LCD and prepares the camera
for another shot.
On/Off switch. This switch, located concentric to the shutter-release button, is
▶
used to turn the camera on and off. Push the switch all the way to the left to turn
the camera off; pull the switch to the right to turn the camera on. The On/Off
switch also has a spring-loaded momentary switch, which, when pulled to the
far right, turns on the control panel backlight.
Movie record button. When the camera is in Live View movie mode (
▶
pressing this button (which has a simple red dot on it) causes the camera to start
recording video. Pressing it a second time stops the video recording. In Live
View still photography mode (
this button has no function at all.
Metering mode button (
