Timings and Sizes
The DSC-T33 uses the really fast Sony Real Imaging Processor™. The operation speed is really fast in both record and play modes. Auto-Focus speeds are more than adequate and on many occasions surpass many prosumer grade cameras, though its accuracy in macro mode may suffer a bit. Power on, focus and JPEG image writing and playback times are very fast when using a Memory Stick DUO Pro card. The flash on the other hand needs some time to recharge, something that's annoying considering its low power.
All times are calculated as an average of three operations. All operations are made at a maximum resolution of 2592 x 1944 pixels, fine quality JPEG image. The media used for these tests was a 256MB Sony Memory Stick DUO Pro card.
Lag Timing Definitions
Most of the modern cameras auto-focus and calculate the exposure needed for each shot when the user half-presses the shutter release button. Half-press Lag is the time needed between half-pressing the shutter release and the camera indicating that focus was achieved and exposure was estimated on the LCD monitor and/or the viewfinder.
The time needed to take a shot by Full-pressing the shutter release, assuming the camera had already focused and evaluated the exposure settings.
The time needed for the camera to take a shot when the shutter release button is fully pressed, without having pre-focused by half-pressing.
File Write / Display and Sizes
Timings shown below are the times needed for the camera to process and store the image to the storage card. The timer is started as soon as the shutter release is pressed and stopped when the activity indicator goes out. The media used for these tests was a 256MB Transcend 45x SD card.
