Twilight mode (low light)

As with the DSC-F505 the DSC-S70 features two Night modes, Twilight and Twilight+. Twilight seems to lock shutter speed at 1/30 sec, Twilight+ allows for longer exposures (up to two seconds with ISO locked at 100). In this mode the LCD refresh rate halves and a brighter preview image appears to be built by combining two frames.

Internal Flash

The flash built into the DSC-S70 has a range rated as 0.3 m (12") - 2.5 m (8.2 ft). It's cunningly positioned away from the lens thus decreasing the possibility for redeye, in real life it's anti-red-eye system (strobe flashes before main flash) worked well (we don't yet have a standard test for redeye).

Skin tone flash test. Fairly good overall colour, slightly blown out possibly because shot was taken at less than rated minimum distance, using flash level "Low" would have solved this slight overexposure.
The S70 coped surprisingly well with our white wall shot (again, the 90% view LCD meant that the bit of wood on the far right wasn't visible when the shot was taken). Drop of is visible but slight.
A good close-up (wouldn't class this as macro) flash shot well metered and lit.
Colour test chart shot @ 10 degrees off horizontal (to decrease reflection). Very good flash white balance with bright accurate colours and gray scale.

Through the S70's menu system you can control flash output by one level up or down, with three settings Low, Normal and High the S70 at least gives an opportunity to correct for it's internal metering system or difficult situations. The three shots below were shot using each flash level.

Flash Level Low
Flash Level Normal Flash Level High

Overall the S70 performed well in our flash tests, the little internal unit performing better than we'd expected with well metered and very natural colour and tonal balance. It's worth noting that the S70 also has an external flash connector for Sony's own HVL-F1000 flash & bracket.

Macro Mode

The Macro mode available on the DSC-S70 allows for reasonably close macro shots, best frame coverage is found about half way through the zoom range at a distance of about 2 cm from the subject. This produces an equivalent of 39.6 mm (1.6") across the frame, not Nikon Coolpix 990 territory but still a very good performance.

Closest frame coverage: 39.6 mm (1.6")

Movie Mode

The S70 features an MPEG movie mode, recording at 15 frames per second with audio. This can be set to either 320x240 or 160x112 resolution. Single button-press recording time can be set to either 10 or 15 seconds. Holding your finger down on the shutter release button allows for longer movies, however at 320x240 the longest recordable movie clip is 15 seconds, at 160x112 this increases to a maximum 60 seconds.
