A ISO Sensitivity Settings The settings available depend on the option selected for Custom Setting b1 ([ISO sensitivity step value], pg. 313). Custom Setting b1 (ISO sensitivity step value) ISO sensitivity settings available 1/3 step (default) LO 1, LO 0.7, LO 0.3, 200, 250, 320, 400, 500, 640, 800, 1000, 1250, 1600, 2000, 2500, 3200, 4000, 5000, 6400, HI 0.3, HI 0.7, HI 1, HI 2 1/2 step LO 1, LO 0.5, 200, 280, 400, 560, 800, 1100, 1600, 2200, 3200, 4500, 6400, HI 0.5, HI 1, HI 2 1 step LO 1, 200, 400, 800, 1600, 3200, 6400, HI 1, HI 2 * If possible, the current ISO sensitivity setting is maintained when the step value is changed. If the current ISO sensitivity setting is not S available at the new step value, ISO sensitivity will be rounded up to the nearest available setting. A HI 0.3-HI 2 The settings [HI 0.3] through [HI 2] correspond to ISO sensitivities 0.3-2 EV over ISO 6400 (ISO 8000-25600 equivalent). Pictures taken at these settings are more likely to be subject to noise and color distortion. A LO 0.3-LO 1 The settings [LO 0.3] through [LO 1] correspond to ISO sensitivities 0.3- 1 EV below ISO 200 (ISO 160-100 equivalent). Use for larger apertures when lighting is bright. Contrast is slightly lower than normal; in most cases, ISO sensitivities of ISO 200 or above are recommended. A See Also For information on Custom Setting b1 ([ISO sensitivity step value], pg. 313).
