Maximum continuous burst6.4 fps6 fps
Lens detailKAF4, KAF3, KAF2 including power zoom, KAF and KA lenses; native KAF2 bayonet with autofocus coupler, information and power contactsKAF4, KAF3, KAF2, KAF and KA lenses; KAF2 power-zoom operation is not supported. Autofocus behaviour depends on in-lens motor or the body screw drive
AutofocusSAFOX 12 phase detection through viewfinder, 33 points including 25 central cross-type points, EV −3 to 18 at ISO 100; contrast detection in live viewThrough-viewfinder SAFOX X phase detection with eleven points including nine central cross-type points; EV −3 to 18 at ISO 100. Live-view hybrid sensor phase/contrast autofocus with face detection, tracking, multiple/select/spot areas and focus peaking
ShutterMechanical focal-plane shutter 1/8000–30 seconds, Bulb and optional timed Bulb 10 seconds–20 minutes; electronic shutter available in live view and tripod pixel shiftMechanical focal-plane 1/6000–30 seconds and Bulb; timed Bulb 10 seconds–20 minutes; electronic shutter for Pixel Shift Resolution rather than a general high-speed electronic mode
Burst detailMaximum 4.4 fps at full-frame resolution with up to 70 JPEGs or 17 RAW files; 6.4 fps in 15-megapixel APS-C crop with up to 100 JPEGs or 50 RAW files, at ISO 100Approximately 6 fps at ISO 100, up to 40 highest-quality large JPEGs, ten RAW or eight RAW/JPEG pairs; 3 fps low-speed mode up to 100 JPEGs, sixteen RAW or eleven pairs
Stabilisation detailFive-axis sensor-shift SR II; maker claims five shutter-speed steps. Built-in GPS supports Astrotracer; horizon and composition adjustment use the sensor-shift mechanismSensor-shift SR; maker claims 4.5 shutter stops in launch notice. Pixel Shift Resolution has selectable subject-motion correction, which cannot correct every moving subject. Astrotracer needs optional O-GPS2; no built-in GPS inferred
FlashHot shoe and X-sync socket for external flash, sync 1/200 secondBuilt-in retractable P-TTL flash, guide number approximately 12 at ISO 100 in metres; 28mm full-frame-equivalent coverage; 1/180-second sync and external dedicated-flash support
Exposure controlsPASM, sensitivity priority and combined shutter/aperture priority; ±5 EV exposure compensation and 86,000-pixel RGB metering sensorPASM, sensitivity priority and combined shutter/aperture priority; 77-segment metering and ±5 EV compensation
