Continuous shooting modes
With the continuous shooting modes you can effectively shoot with
reduced image size up to 60 frames per second. Full resolution images
are recorded at either 12, 5.5 or 2 frames per second.
At the full 12 fps burst rate you can capture up to 12 images in one burst
whilst at the slower speeds you are limited only by memory buffer.
To achieve the 12fps stated performance with full resolution fine quality
JPEG images you need to use the class 6 SDHC memory card specified
for video. Ideally this mode is used for very short bursts of image
capture.
When you shoot at the 5.5fps single AF mode you will find that you can
shoot around 12-15 images before the actual speed drops dramatically
as the camera buffer fills and empties to the SDHC card.
The speed drops to about 2 fps after the initial 2-3 seconds of 5.5 fps
burst.
In the single AF mode exposure and focus are fixed for the first exposure
of the burst sequence. This means that if your subject is moving towards,
or away from, the camera focus may not be maintained.
This will depend upon the lens aperture and focal length as this will
determine the depth of field available during the burst sequence.
If you select the continuous autofocus mode the camera is forced to
focus for each image.
You can also use manual focus and this speeds up the first image
capture as the camera does not have to autofocus!
