The monitor screen is a 230k 2.7-inch TFT unit. It's nice and bright, and its anti-reflective surface means it works well in sunlight, but it does have a somewhat restricted viewing angle of about 60 degrees in all directions, which can be a bit annoying if you're holding the camera above your head to shoot over a crowd, or trying to show pictures to more than one person at once.
The S570 has only the most basic range of features, but it is very easy to use. It has only four shooting modes; Full auto, Scene mode with 16 scene programs and Auto Scene Selection, Smart Portrait mode with enhanced skin tones, blink warning and smile timer, and the video recording mode. Video recording is limited to 640 x 480 resolution at 30fps with mono audio, with a maximum clip length of 25 minutes if you have a big enough card. As with most low-cost cameras the optical zoom cannot be used while recording.
The S570 does have some useful automatic functions that are transparent to the user, such as automatic red-eye correction. It doesn't have any mechanical image stabilisation, but it does have Electronic VR (digital image stabilisation). This is reasonably effective, but it does have an impact on image quality. It's a technology better suited to video recording than stills. It also has a 3200 ISO maximum sensitivity and a blur detection function which alerts you if the shot you just took wasn't sharp.
The main menu has barely two pages, with only six options including image size, white balance, drive mode, ISO setting and AF area. There is no spot metering, and creative control is limited to a short list of colour options. Exposure compensation, flash mode, macro mode and the self timer are found as button functions on the D-pad. Despite its comparative lack of features, what little the S570 does offer is well implemented and works well. The menu is also shooting-priority; a tap of the shutter button returns the camera to shooting mode.
There are a number of useful features in playback mode including automatic Quick Retouch, D-lighting and skin softening. These are all easy to use with one-click operation, and produce quite good results.
