Rear of Camera Controls

The control layout at the rear of the D80 is less like the D70 and more like the D50, although even compared to it there are some differences. Just as with the D50 three of the buttons running down the left side of the LCD monitor have dual-purpose, in shooting mode they allow you to set White balance, ISO sensitivity and Image Quality / Size, in Playback mode the provide other functions. Sensibly on the right side the D50's Erase button has become 'OK' and the Enter button is gone for good. Press and hold the erase and metering (top of camera) buttons, release and repeat to format the SD card.

Single press buttons (Shooting mode)

Button	Description
AE-L AF-L	Auto Exposure and Auto Focus Lock Pressing this button locks the current exposure and focus, they remain locked for as long as you hold the button even if you press or release the shutter release button. The exact function of this button can be set via CSM 18.
	Playback mode Enters or exits from Playback mode, pressing this button displays the last image taken (or the last image on the card) in the last used display mode.
MENU	Camera menu Display or cancel the camera menu (detailed later in this review).
	Help Press and hold this button in Auto or one of the Vari-Program modes to display a page of help, this also works in the cameras menu system.
	4-way controller In shooting mode where AF point selection is enabled the 4-way controller is used to choose AF points. In playback mode this control reverts to image navigation / menu movement. Note that this control can be locked to avoid accidentally changing AF area using the lock lever just below it (the lock lever has no effect on menu or playback functionality).

Single press buttons (Playback mode)

Button	Description
	Delete When an image is displayed pressing delete will display a "Delete?" prompt, press this button once more to delete the image. This is quicker and more straightforward than the D100 which required confirmation with a different button.
MENU	Camera menu Display or cancel the camera menu (detailed later in this review).
	Protect Protects or un-protects the current image. This places a read-only flag on the image file and stops it from being accidentally deleted or deleted using a 'delete all images' option. It does not protect the image from a card format.
	Zoom out / Thumbnail view If a single image is displayed on the screen pressing this button switches to 2x2 and then 3x3 thumbnail views. In zoom view mode pressing this button steps out of magnification.
	Zoom in If a single image is displayed on the screen pressing this button enters zoom view mode and steps into the first level of magnification, there are 8 levels up to 25x (although it's clear looking at the screen that there's no more detail beyond about 12x). In thumbnail view mode pressing this button steps back towards a single image view.
	4-way controller Press left or right to browse through images, up or down to change display mode: Image with simple info, Image & information page 1, Image & information page 2, Image & highlights, Image & RGB histogram.
OK	Retouching menu Pressing the OK button in Playback mode displays a pop-up version of the retouching menu.

On the left side of the camera front are two unlabelled buttons, the bottom is depth of field preview, press and hold this button to stop the lens down to the selected aperture. The top button is the customizable 'FUNC' button, the exact function of this button can be set via CSM 16, although it defaults to displaying the ISO sensitivity on the viewfinder status bar and top control panel when pressed. On the right side of the camera we have the flash button, bracket mode and just below the lens release the focus mode lever.
