Two years after the original FinePix S1 Pro, the S2 Pro was introduced in 2002.
Although both the FinePix S2 Pro and the Nikon D100 were designed based on the Nikon F80, the appearance of both cameras, the layout and positioning of the commands as well as the available menus are quite different.
Considering their mutual backbone and the market they aimed to serve, the S2 Pro and the D100 were direct competitors.
Adding the Canon EOS D60 to this duo, three 6 effective MP DSLR cameras were introduced to the market simultaneously.
Other than all features that can be found on the Nikon F80 camera, including the Nikon F mount, the FinePix has been boosted with a host of extra features. It was truly packed with many refinements over its predecessor, which was based on the Nikon F60.
Electronics were Fuji's.
The camera takes CompactFlash memory cards (including micro-drives) and SmartMedia cards.
The main highlight of the S2 Pro was the 3rd generation Super CCD sensor with its unique octagonal-shaped photo diodes, rotated 45° compared to conventional CCD’s used by Nikon and Canon.
Eventhough the sensor has an image capacity of 6.17 million effective image pixels, it is capable of producing 12.1 million (4,256 x 2,848) recorded pixels due to the presence of 2 sensors per location: one for normal light and one for bright lights, resulting in a higher dynamic range and enough for quality printing at sizes well above A3.
This camera has the Nikon F-mount and accepts most Nikon lenses (Nikkor and Series E):
- Most modern autofocus lenses (excluding the lenses specifically developed for the F3AF camera): AF, AF-D, AF-S, including the newest "DX" and "G" (without aperture ring) lenses.
- Older Ai (including Series E lenses) and Ais lenses. These lenses will not meter, except if they have been modified with a "chip", which provides certain lens parameters electronically to the camera.
This camera has an unusual, even bizarre, power system. It takes 4 AA cells (lithium primary or NiMH rechargeable batteries strongly preferred over alkaline), and two CR123A lithium batteries. The CR123As are sort-of optional; if they're left out, everything works except the built-in flash (but you get notably shorter life on the AAs).
If CR123As are in use, and become exhausted, the camera will sometimes lock up completely. Turning off the camera, removing the CR123As, and turning the camera back on will normally bring it back to life.
