FinePix S3 Pro

The Fujifilm FinePix S3 Pro is an interchangeable lens digital single-lens reflex camera introduced in February 2004. Its successor, the Finepix S5 Pro, was released on 25 September 2006. It is based on a Nikon F80 (N80 in the U.S.) viewfinder, shutter, mirror-box and autofocus modules surrounded by a Fujifilm body that includes its own proprietary CCD image sensor and electronics, and a vertical grip shutter release. It has a Nikon F lens mount and can use most lenses made for 35 mm Nikon SLR cameras, but only with manual operation with Nikon AIS lenses, unusually for a digital SLR the S3 Pro can be used with a manual cable release.

It is autofocusing and has an electronically controlled focal plane shutter with speeds from 30 sec. to 1/4000 sec. with x-flash synchronization at shutter speeds up to 1/180 sec. It has built-in exposure metering with spot, center weighted and evaluative modes and also features a pop-up flash. Its ISO film speed equivalents range from 100 through 125, 160, 200, 400, 800 and 1600. The camera is discontinued and no longer in production.

The camera's principal distinction is its 23mm x 15.5mm photo sensor. Designated the Super CCD SR, it is unique in two ways. First, like its predecessors used in the earlier FinePix S1 Pro and FinePix S2 Pro, it has its photodiodes oriented diagonally rather than horizontally and vertically as in all other DSLR cameras. This allows the use of a sophisticated interpolation system that produces an output image equivalent to 12.1 megapixels. The apparent resolution of images in this interpolated mode lay somewhere between 6.17 megapixels and the 12.34 megapixel interpolated output.
