Checking the number of recordable images/recording time
Others
“Memory Stick PRO Duo” (h (hour), m (minute))
Notes The recordable time of movies varies for the reason that the camera equipped with 
VBR (Variable Bit Rate) which automatically adjusts image quality depending on 
shooting scene. When you record fast-moving subject, the image is clearer but the 
recordable time is shorter because it spends much memory to record. The recordable 
time also vary depending on the shooting condition or subject or setting of image 
quality/size.
 The values shown are not the continuous recording time.
 Recording time may depend on shooting conditions and the memory card used.
 When   is indicated, stop recording the movie. The temperature inside the camera 
has increased to an unacceptable level.
 For details on movie playback, see page 33.
 It requires a lot of power to perform high quality movie recording or continuous 
shooting using the APS-C size image sensor. Therefore, if you continue to shoot, the 
temperature inside the camera will rise, especially that of the image sensor. In such 
cases, the camera is turned off automatically since higher temperatures affect the 
quality of the images or burden the internal mechanism of the camera.
 The duration of time available for movie recording is as follows when the camera 
starts recording after the power of the camera has been turned off for a while. (The Capacity

							Checking the number of recordable images/recording time

following values indicate the continuous time from when the camera starts recording 
until the camera stops recording.)
 The duration of time available for movie recording varies with the temperature or 
condition of the camera before you start recording. If you frequently recompose or 
shoot images after the power is turned on, the temperature inside the camera rises 
and the recording time available is shorter than the values indicated in the table 
above.
 If the camera stops recording due to the temperature, leave it for several minutes 
with the power turned off. Start recording after the temperature inside the camera 
drops fully.
 If you observe the following points, the recording time is longer.
– Keep the camera out of direct sunlight.
– Turn the camera off when it is not being used.
– If possible, use a tripod and disable the SteadyShot function.
 The maximum size of a movie file is about 2 GB. When the file size is about 2 GB, 
the recording stops automatically when [File Format] is set to [MP4], and a new 
movie file is created automatically when [File Format] is set to [AVCHD].
 The maximum continuous recording time is 29 minutes.Ambient temperatureContinuous recording time

* The values for equivalent 35mm-format focal length and angle of view are based 
on Interchangeable Lens Digital Camera equipped with an APS-C sized image 
sensor.
** Minimum focus is the shortest distance from the image sensor to the subject.
 This lens is equipped with a distance encoder. The distance encoder allows more 
accurate measurement (ADI) by using a flash for ADI.
 Depending on the lens mechanism, the focal length may change with any change of 
the shooting distance. The focal length assumes the lens is focused at infinity.
 The infinity position provides for some adjustment to compensate for focus shift 
caused by change in temperature. To shoot a subject at infinite distance in MF mode, 
use the viewfinder and set focus.
On focal length
The picture angle of this camera is narrower than that of a 35 mm-format 
camera. You can find the approximate equivalent of the focal length of a 35 mm-
format camera, and shoot with the same picture angle, by increasing the focal 
length of your lens by half.
