Like so many 10- and 12-megapixel compacts, FujiFilm's F50fd performs great at low ISOs, but image quality suffers dramatically as the sensitivity climbs. At ISO 100, resolution is Excellent (2300), Noise is Low (1.9), and Color is Excellent (Average Delta E: 7.4 Manual White Balance, ISO 100). At ISO 200, noise is Moderately Low (2.2). But it climbs to Moderate at ISO 400 (2.7) and ISO 800 (2.8). At ISO 1600, the last full-resolution ISO, Noise is Unacceptable (4.0), and Resolution drops significantly to Extremely High (1525). Shedding half its megapixels to double the sensitivity at ISO 3200, Noise climbs even higher into Unacceptable territory (4.7), and with less recording pixels, its only natural the Resolution drops yet again, staying just this side of Acceptable (1110). Shedding half its pixels once again for 3MP ISO 6400 mode, Noise climbs yet again (Unacceptable 5.4), and Resolution drops to an abysmal Unacceptable (800).
