Metering: 3D color matrix: Center-weighted: Spot: TTL full-aperture exposure metering system with three metering modes 3D color matrix metering using 1,005-pixel CCD supported when D-Type Nikkor lens is attached; with other lenses, color matrix metering using 1,005-pixel CCD is supported Greatest weight (75% of total) given to a circle in the center of the frame 8 mm in diameter Exposure determined by 4 mm circle in center of frame (approx. 2% of frame); when a CPU Nikkor lens is attached, any of the five focus areas can be used for spot metering Exposure range: At ISO 100, room temperature, and with f/1.4 lens, 0-20 EV (center-weighted and 3D color matrix metering) or 2-20 EV (spot metering) Metering coupling: Combined CPU and AI Exposure compensation: -5 to +5 EV in increments of 1/3 EV; exposure compensation indicator appears in viewfinder and top control panel Auto-exposure lock: Detected exposure locked when AE/AF lock button is pressed Auto bracketing: Two or three exposures with compensation in increments of 1/3, 1/2, or 1 EV Shutter: Speed: Combined electronic (CCD) and mechanical shutter 30-1/16,000 sec. (1/3 increments), long time exposure (bulb) Speedlight Sync contact: X-contact only; flash synchronization at shutter speeds of Flash control: 1/500 sec. or slower. (1) Automatic balanced fill-flash controlled by five-segment TTL multi-sensor with single-component IC. If SB-28DX Speedlight is combined with a D-Type AF-Nikkor lens, 3D multi-sensor balanced fill-flash for D1 is used. If the SB-28DX is combined with AI-P or AF Nikkor lens other than D-Type, multi-sensor balanced fill-flash for D1 is used. If the SB-28DX is combined with a non-CPU Nikkor lens, balanced TTL flash for the D1 can be used with center-weighted metering. (2) Auto aperture (AA) flash: supported with SB-28DX and CPU Nikkor lenses (3) Non-TTL auto flash: supported with SB-28, SB-27, and SB- 22s Speedlights Flash sync modes: Front curtain (normal) sync, red-eye reduction, red-eye reduc- tion with slow sync, slow sync, rear curtain Ready light: Lights when flash SB-28DX, SB-28, SB-27, or SB-22s is fully charged; blinks for three seconds after being fired at full output Accessory shoe: Standard ISO hot-shoe contact with safety lock Sync terminal: Standard JIS terminal with locking screw Self timer: Electronically controlled timer, duration 2-20 seconds Technical Notes: Specifications 125
