OverviewAs successor of the DSC-F717, F828 was widely considered "revolutionary" at launch, for its newly-designed high-spec lens, sensor and processing circuits. F828's new "Carl Zeiss T*" -badged lens has a zoom range of 7x (28-200mm), wider compared to F717's 5x (38-190mm). It was fitted with 8.0 megapixel, 2/3 inch, 4-color RGBE CCDs, which had the highest pixel counts in any consumer camera sensors at the time. Upgraded chipset enables F828 to focus and post-process faster than its predecessor. Thanks to the new system, features such as continuous AF, and VGA-quality (640x480) filming were made possible. The addition of a CF slot allows users to use a CompactFlash card, which is a cheaper and more universal alternative to Sony's proprietary Memory Sticks. Although, a Memory Stick Pro is required for VGA-quality filming. The F828, along with the "Cyber-shot F" series designation, was discontinued in 2005. ReceptionDespite having attractive on-paper specs, F828 did not fare as well as its predecessor among camera reviewers and photographers. F828 received a "Recommended / Above average" rating from DPReview, in contrast to a "Highly recommended" given to F717. Average user rating is 43 out of 100 from cameradecision.com. Visible picture noise, associated with increased pixel density and underdeveloped noise reduction algorithm, was of primary concern. Moreover, the complicated RGBE sensor did not result in better color accuracy as expected; this led Sony to drop any further development on such sensors, making F828 the first and the last camera ever to use a 4-color sensor. Many photographers also noted more severe purple fringing on F828s than on its predecessors. References
