The Finecam S3 is unusual among ultra-compacts in that it allows you to select aperture, however as with most compact lens designs there are only two available apertures which are labelled as F2.8 and F6.2 (at wide angle). These apertures equate to:
- At wide angle (38 mm equiv.): F2.8 / F6.2
- At telephoto (76 mm equiv.): F3.5 / F7.6
Selecting the F6.2 / F7.6 aperture does give you a little more depth of field:
|F3.3, 1/39 sec||F7.2, 1/9 sec|
Macro focus mode
The Finecam S3 does quite well in macro mode as long as you set zoom to full wide angle, at this setting we found you could get close enough to get a frame coverage of approximately 5 cm (2 in) which is really rather good for an ultra-compact.
Low Light Focus
In a new addition to our reviews we'll now be measuring the minimum amount of light under which the camera can still focus. The focus target is our lens distortion test chart (shown here on the right), camera is positioned exactly 2 m (6.6 ft) away. Light levels are gradually dropped until the camera can no longer focus.
This test target is the optimum type of subject for most "contrast
detect" AF systems (as it has a vertical line at its center), if
the subject were less easy to focus upon then you would need more light.
- Kyocera Finecam S3 best low light focus: 4.3 EV (49.2 Lux / 4.58 foot-candle) *
* At any sensitivity
The S3 isn't built to focus in low light, needing 4.3 EV of light before it can focus on our ideal AF target you may need even more light to focus on something with little contrast (such as human skin).
The S3's tiny flash manages to create plenty of coverage, it's rated as having a range of 2.5 m at wide angle and we had no reason to doubt that. However, as you can see below there was a strange colour cast on skin tones when using the flash.
