APower Source and Frame Rate

The frame advance rate varies with the power source used.

Power source	Frame advance rate (approx.) 1
Battery (EN-EL3e)	7 fps
AC adapter	7.6 fps 2
MB-D10 battery pack with EN-EL3e battery	7 fps
MB-D10 battery pack with EN-EL4a battery	8 fps 2
MB-D10 battery pack with AA-size batteries 3	7.7 fps 2

1Average frame rate with continuous-servo AF, manual or shutter-priority auto exposure, a shutter speed of 1/250 s or faster, other settings at default values,

and memory remaining in memory buffer. Frame advance rate when recording NEF (RAW) or NEF (RAW) + JPEG pictures with 14-bit selected for NEF (RAW) recording > NEF (RAW) bit depth (0 70) is approximately

2.5 fps. Frame rate drops when vibration reduction (available with VR lenses) is on.

2If On is selected for ISO sensitivity settings > ISO sensitivity auto control in the shooting menu (0 98), frame advance rate in continuous high-speed

mode is approximately 7.5 fps.

3Frame rate slows at low temperatures and when batteries are low.

A Buffer Size

The approximate number of images that can be stored in the memory buffer at current settings is shown in the exposure-count displays in the viewfinder and control panel while the shutter- release button is pressed. The illustration at right shows the display when space remains in the buffer for about 37 pictures.
