Shooting (P, S, A, M)
Live view ends unexpectedly or does not start: Live view may end automatically
to prevent damage to the camera’s internal circuits if:
• The ambient temperature is high
• The camera has been used for extended periods in live view or to
record movies
• The camera has been used in continuous release modes for extended
periods
If live view does not start when you press the a button, wait for the
internal circuits to cool and then try again. Note that the camera may feel
warm to the touch, but this does not indicate a malfunction.
Image artifacts appear during live view: “Noise” (randomly-spaced bright
pixels, fog, or lines) and unexpected colors may appear if you zoom in on
the view through the lens (0 57) during live view; in movies, the amount
and distribution of randomly-spaced bright pixels, fog, and bright spots
is affected by frame size and rate (0 188). Randomly-spaced bright
pixels, fog, or bright spots may also arise as a result of increases in the
temperature of the camera’s internal circuits during live view; exit live
view when the camera is not in use.
Menu item can not be selected: Some options are not available in all modes.
Shutter-release disabled:
• Non-CPU lens is attached: rotate camera mode dial to M (0 72).
• Mode dial rotated to S after shutter speed of A or % selected in
mode M: choose new shutter speed (0 74).
Full range of shutter speeds not available: Flash in use. Flash sync speed can be
selected using Custom Setting e1 (Flash sync speed); when using
compatible flash units, choose 1/320 s (Auto FP) or 1/250 s (Auto FP)
for full range of shutter speeds (0 265).
