Review based on a production Cybershot DSC-F828
The Cybershot DSC-F828 was announced on 15th August, this new camera is very obviously a development of the DSC-F717 design. Just under a year since the F717 and Sony's flagship prosumer digital camera has certainly undergone a large number of changes, not least of which is the switch from the electronically zoomed five times lens of the F707/F717 to an all new mechanical zoom seven times lens with Carl Zeiss T* coating and a wide angle 28 mm equiv. capability. Sony has also chosen to go with their latest sensor, the all new eight megapixel four-color (RGBE) 2/3" type (8.8 x 6.6 mm) CCD. Ignoring all other changes this makes a formidable combination, a high quality mechanically linked zoom lens combined with the resolution of an eight megapixel CCD. This camera is arguably the most important prosumer digital camera this year.
It's worth remembering that Sony first introduced this unusual large lens, split body swivel design back in August 1999 with the DSC-F505 (the 13th camera ever reviewed on this site!). Back then the F505 had a 35 - 190 mm five times optical zoom lens and two megapixel sensor, this camera was developed into the F505V in April 2000 which used 2.6 megapixels of a three megapixel sensor. The five megapixel DSC-F707 appeared in August 2001 (IFA 2001), this was updated to the DSC-F717 in September 2002 (Photokina 2002).

On June 11 news surfaced of a new Sony sensor with an amazing eight megapixels. This sensor took the same 2/3" type size (8.8 x 6.6 mm) of the previous five megapixel sensor used in the DSC-F717. At this size and resolution the pixel pitch (distance between pixels) is just 2.7 µm, extremely small and this raised questions of noise and sensitivity, those answer we will only be able to deliver in our full review.
Just a month later on July 16 Sony announced that they had developed a new four color RGBE color filter array (at the time we noted that it would be likely used on the new eight megapixel CCD but had no confirmation of this fact). Instead of the traditional RGB color filter array the new CFA is made up of Red, Green, Blue and Emerald (like Cyan) color filters. Sony claim that this expands the gamut of color which the sensor can capture and greatly improves color response.

Conclusion / Recommendation / Ratings are based on the opinion of the reviewer, you should read the ENTIRE review before coming to your own conclusions. Images which can be viewed at a larger size have a small magnifying glass icon in the bottom right corner of the image, clicking on the image will display a larger (typically VGA) image in a new window. To navigate the review simply use the next / previous page buttons, to jump to a particular section either pick the section from the drop down or select it from the navigation bar at the top. DPReview calibrate their monitors using Color Vision OptiCal at the (fairly well accepted) PC normal gamma 2.2, this means that on our monitors we can make out the difference between all of the (computer generated) grayscale blocks below. We recommend to make the most of this review you should be able to see the difference (at least) between X,Y and Z and ideally A,B and C. |
