Quick-return half mirror (Transmission: reflection ratio of 37:63)

Depth-of-Field Preview
Enabled with depth-of-field preview button

Eyepiece Shutter

TTL-AREA-SIR AF-dedicated CMOS sensor

AF Points
Area AF with 45 AF points
- 8 mm (H) x 15 mm (W)
- All 45 AF points are horizontal-line sensitive at f/5.6 (vertical). Thirty-nine of the 45 AF points are vertical-line sensitive at f/2.8 for cross-type focusing. For automatic AF point selection, cross-type focusing with 19 AF points is used. (The 39 cross-type AF points are used only during manual AF point selection.)
- When using some f/4 lenses (including when using f/2.8 lens + Extender 1.4x), cross-type focusing with 39 AF point is possible.

Metering Range
EV -1-18 (at 23°C/73°F with 50mm f/1.4 lens at ISO 100)

Focusing Modes
1) One-Shot AF
2) Predictive AI Servo AF
- The following can be set: C.Fn III -2: Focus-tracking sensitivity, C.Fn III -3:
Servo operation method and shutter-release timing, C.Fn III -4: Servo operation method in case a closer object enters the focus center during subject-tracking.
(2) Manual focus

AF Point Selection
1) The 45 AF points can be selected automatically or any one of them can be selected manually. To select an AF point, press the AF point selection button, then use the Multi-controller, Main Dial, or Quick Control Dial. With C.FN III -8-3, the 18 expanded AF points are instead used to search for the subject.
2) During manual AF point selection, the six AF points (or 26 AF points during automatic AF point selection) other than the 39 cross-type AF points will work as horizontal line-sensitive sensors at f/5.6. The two AF points at the immediate top and bottom of the center AF point have improved detection performance and precision due to the increase in the number of lines to two for the f/5.6 sensor. (The 39 cross-type AF points are used only during manual AF point selection.)

Selected AF Point Display
Superimposed in viewfinder and on LCD panel

AF-assist Beam
- When an external, EOS-dedicated Speedlite is attached to the camera, the AF-assist beam from the Speedlite will be emitted when necessary.
- Compatible with the 270EX's AF-assist beam (a series of small flashes)

(4) Center-Weighted average metering

Metering Range
EV 0-20 (at 23°C/73°F with 50mm f/1.4 lens at ISO 100)

Exposure Control
Program AE (shiftable), Shutter speed-priority AE, Aperture-priority AE, E-TTL II program AE (Evaluative flash metering, Averaged flash metering), Manual

ISO Speed (Recommended Exposure Index)
Auto, ISO 100-12800 (1/3-stop or 1-stop increments: C.Fn I -2), Expandable
- ISO Auto set by default. With all C.Fn to their default setting, automatically set within ISO 100-12800.
- With C.Fn I -3 (ISO speed range), the highest and lowest settable ISO speed can be set. By setting L (ISO 50) for the lowest speed and H1 (ISO 25600), H2 (ISO 51200), H3 (ISO 102400) [TD] for the highest, ISO speed expansion is possible.
- In manual ISO setting, if the upper ISO speed limit is set to H1, H2, H3 [TD], and the lower ISO speed limit to L with C.Fn I-3, the settable ISO speed range will be ISO 100-12800.
- In ISO Auto, even if the upper ISO speed limit is set to H1, H2, H3 [TD], and the lower ISO speed limit to L with C.Fn I-3, ISO Auto speed range will be ISO 100-12800. However, if the lower and higher ISO speed limits have been set to a narrower range, ISO speed will be automatically set within that range.
- In P, Tv, Av modes and C.Fn I -8-2 (Tv/Av safety shift) is set, C.Fn I -3's ISO range limit will be canceled when the standard exposure cannot be obtained, even if C.Fn I-3 has set the lowest and highest settable ISO speed to a narrower range. It will be automatically controlled within the range of ISO100-12800.
- In ISO Auto and C.Fn I-8-1 (Tv/Av safety shift) is set, the C.Fn I-12's shutter speed range limit and C.Fn I-13's aperture range limit will be canceled when the standard exposure cannot be obtained. C.Fn I-3's upper and lower limits will be applied to control the ISO speed range. With C.Fn II-3 (Highlight tone priority) set, even if C.Fn I-3 has set the lower ISO speed limit to L and the upper ISO speed limit to H1, H2, H3, the ISO Auto range and manual ISO range will be ISO 200-12800. However, if the lower and higher ISO speed limits have been set to a narrower range with C.Fn I-3, the settable range will be ISO 200 to the higher speed limit set.
- When checking the ISO speed of still photos or movies shot at H3 (ISO 102400) in commercially available software, the correct ISO speed value may not be displayed (the EXIF information standard cannot record ISO 102400 settings).
- When imprinting the shooting information for images shot at H2, H3 ISO speeds during ISO speed range expansion, the ISO speed setting may not be correctly printed.

Exposure Compensation
Exposure Compensation (user-set): +/-3 stops in 1/3- or 1/2-stop increments.
Auto Bracketing (AEB): 3 shots, up to +/- 3 stops, in 1/3 or 1/2 stop increments, in all exposure modes. Can be changed via C.Fn I-6 to 2, 5, or 7 shots. Bracketing order can be changed via C.Fn I-5.
*Except during movie Manual exposure.

"Flash sync to 1/300"

I wish Nikon would allow their flash sync to go above 1/250 to 1/320. That would be a nice improvement when shooting moving subjects in low light such as at sporting events.

"Picture Style
Standard, Portrait, Landscape, Neutral, Faithful, Monochrome, User Def. 1-3"

Although you can download the Portrait and Landscape modes, it would be more convenient if Nikon added the Portrait and Landscape modes with their current picture control modes.
