Timings and Sizes
The DC C-50 surely isn't a fast operating camera. You could say that its speed in most operations is average, but take note that at this price and with big, 5MP images, anything faster would be a big surprise. However, focus and image recording times surely won't disappoint the average snapper, nor will the average shutter lag which is pretty much standard in this category.
Test Notes:
All times are calculated as an average of three operations. All operations are based on a maximum resolution of 2560 x 1920 pixels, fine quality JPEG image. The media used for these tests was a 256MB Transcend 45x SD card.

Lag Timing Definitions
Half-press Lag (0->S1) |
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. |
Half to Full-press lag (S1->S2) |
The time needed to take a shot by Full-pressing the shutter release, assuming the camera had already focused and evaluated the exposure settings. |
Full-press Lag (0->S2) |
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.
