Maximum continuous burst9 fps5.5 fps
Lens detailCompatible F-mount lenses include G/E/D, other supported AF, P and AI non-CPU lenses with restrictions; DX lenses use a cropped image area. Non-AI, IX and F3AF lenses unsupported.F mount with body AF coupling and contacts; G/E/D, other AF and AI-P lenses with restrictions, non-CPU lenses and DX crop support. Collapsible metering lever allows compatible non-AI lenses; register focal length/maximum aperture and match camera aperture setting to lens ring for metering in A/M. IX and F3AF lenses excluded; Digital Camera World's all-mode AI metering wording should not be applied indiscriminately to non-CPU lenses
AutofocusViewfinder Multi-CAM 20K phase detection with 153 points, 99 cross-type and 55 user-selectable; 15 support f/8. Live view uses contrast detection with face, wide, normal, pinpoint and tracking modes. Review references to a Multi-CAM 3500 module are incorrect.Multi-CAM4800 phase detection with 39 points, nine cross-type and seven central f/8-compatible points; -1 to +19 EV at ISO 100, 20°C. AF-S/AF-C, fine-tuning, single-point, dynamic nine/21/39, 3D tracking and auto-area. Live view uses contrast AF-S/AF-F and face/wide/normal/tracking areas; current USA AF-A listings conflict with Japan's modes and USA's own live-view AF-F table, while Photography Blog's 51-point dynamic description conflicts with maker 39
Shutter1/8000 to 30 seconds, Bulb and Time; mechanical focal-plane and electronic front-curtain options; flash sync 1/250 second with compatible Auto FP support; electronic silent live-view modesElectronically controlled vertical-travel focal-plane shutter; mechanical dial selects 1/4000 to 4 seconds in whole stops, command dial extends to 30 seconds in one-third stops; Bulb and Time. X-sync 1/200 second, up to 1/250 with reduced flash range
Burst detailMain 9 fps requires optional MB-D18 grip, EN-EL18b battery and BL-5 cover; body with EN-EL15-series battery reaches 7 fps. Full-resolution silent Mode 1 reaches 6 fps. Brief silent Mode 2 reaches 30 fps for at most three seconds with fixed focus/exposure and 3600 × 2400 DX JPEG Normal files; this restricted mode is not the headline continuous rate.Approximately 5.5 fps full-resolution continuous high or 1–5 fps continuous low; USA conditions specify manual focus, M/S, 1/250 second or faster and other settings at defaults. Quiet single-frame, mirror-up and configurable self-timer; Photography Blog's quiet-continuous 3 fps claim conflicts with maker's listed release modes. Japan buffer table gives 100 Large Fine JPEGs or 29 lossless-compressed 14-bit RAW frames at ISO 100 with SanDisk SDSDXPA-008G-J35 SDHC and specified settings; Digital Camera World's 37 RAW 14-bit claim differs
Stabilisation detailNo sensor-shift stabilisation; optical VR depends on the attached lens. Electronic movie vibration reduction available with mode restrictions.VR depends on attached lens; no sensor-shift stabilisation
FlashNo built-in flash; ISO 518 hot shoe, ISO 519 sync terminal and compatible external i-TTL SpeedlightsNo built-in flash; external i-TTL Speedlights, hot shoe and ISO 519 PC sync terminal, compatible Auto FP up to 1/4000. Current USA flash-control text mentions a nonexistent built-in flash, while Photography Blog denies the PC terminal despite listing it elsewhere; Japan explicitly confirms the terminal
Exposure controlsP/S/A/M; ±5 EV compensation; 180K-pixel RGB metering sensor, unlike Photography Blog's erroneous 91K-pixel narrativeP/S/A/M; 2016-pixel RGB matrix, centre-weighted and spot metering; ±3 EV compensation, exposure/flash and white-balance bracketing; two-exposure HDR, interval timer and dual-axis virtual horizon. Mechanical exposure dials remain readable when powered off
