Casio Exilim EX-S770 - Casio Exilim EX-S770
The S770 is full of clever little features like that, such as the automatic document correction, in which a photo taken of a document from any angle it straightened so that the sides are parallel, or the colour restoration feature, in which you can take a photo of an old print, and then automatically restore faded colours.
It also features something called Casio Document Transport, the software for which has to be installed on your PC from the accompanying CD. It allows you to export documents from any other software as though you were outputting to a printer, but instead copies them to the camera’s memory card via the supplied USB/charger docking cradle. Since it appears to save them as a JPG image I’m not sure that I’d find it that useful, but I suppose it might be handy for presentations or something.
Image quality is also very good. Despite the terminally overcast weather I was able to take some decent test shots, and I was suitably impressed by the level of detail, colour rendition, exposure accuracy and noise control. The lens does suffer from very visible spherical distortion at its widest angle setting, but provides very good overall sharpness right into the corners, with no chromatic aberration visible. There was also a refreshing lack of colour fringing on high-contrast shots.
The S770 has manually selectable ISO settings up to 400, with 800ISO available as an automatic setting in Anti-Shake mode. There was some noise visible at 400, and a fair bit at 800, but results were significantly better than some other 7MP compacts I’ve tested recently. Indoor flash shots were also very good, with excellent frame coverage and colour reproduction, and very fast recharge time.
My only real criticism of the S770, apart from the lens distortion, is that the full manual is only included as a PDF document hidden away on the software CD. Please can we stop doing this?
Apart from the wide-angle distortion and the CD manual I have nothing but praise for the S770. In my opinion it is currently the best ultra-compact digital camera on the market. Considering build quality, design, performance, value for money and photographic results it is comfortably ahead of the competition in every respect.
