Chapter 1: Getting the Lay of the Land
button as the AF Point Selection button. Again, though, the margin icons help
you know exactly which button is being described.
And here’s another tip: If the label or icon for a button is blue, it indicates a
function related to viewing, printing, or downloading images. Labels that indi-
cate a shooting-related function are white, and the sole red label indicates a
button purpose related to Live View and movie shooting.
With that preamble out of the way, it’s time to explore the camera back, start-
ing at the top-right corner and working westward (well, assuming that your
lens is pointing north, anyway):
✓
AF Point Selection/Magnify button:
When you use certain advanced
shooting modes, you press this button to specify which of the nine auto-
focus points you want the camera to use when establishing focus. Chapter
8 tells you more. In Playback, Live View, and Movie modes, you use this
button to magnify the image display (thus the plus sign in the button’s
magnifying glass icon). See Chapter 5 for help with that function.
✓
AE Lock/FE Lock/Index/Reduce button:
As you can guess from the offi-
cial name of this button, it serves many purposes. The first two are
related to still-image capture functions: You use the button to lock in the
autoexposure (AE) settings and to lock flash exposure (FE). Chapter 7
details both issues. When using Live View and Movie modes, covered in
Chapter 4, this button serves only as an autoexposure lock.
This button also serves two image-viewing functions: It switches the
display to Index mode, enabling you to see multiple image thumbnails at
once, and it reduces the magnification of images when displayed one at
a time. Chapter 5 explains picture playback.
✓
Speaker:
When you play a movie that contains an audio track, the sound
comes wafting through these little holes, which lead to the camera’s
internal speakers.
✓
Aperture/Exposure Compensation/Erase button:
When you work in M
(manual) exposure mode, you press this button and rotate the Main dial
to choose the aperture setting, better known as the
f-stop.
In the other
advanced exposure modes (P, Tv, Av, and A-DEP), you instead use the
button and dial to apply
Exposure Compensation,
a feature that enables
you to adjust the exposure selected by the camera’s autoexposure
mechanism. Chapter 7 discusses both issues. Sporting a trash can icon
(the universal symbol for delete), use this button to erase pictures from
your memory card during playback. Chapter 5 has specifics.
✓
Live View/Movie button:
Press this button to shift the camera into Live
View mode and, when shooting movies, to start and stop recording. (For
the latter, you must first set the Mode dial to Movie mode.) Chapter 4
offers the pertinent details.
