Lens detailZEISS Vario-Sonnar T*, actual 4.3–215 mm; 15 elements in 10 groups including one Super ED, two ED and three aspherical elements, seven-blade iris. Equivalent 24–1200 mm applies to full-resolution 4:3 stills; other aspect ratios and movie stabilisation modes have different crops. Clear Image Zoom and digital zoom are distinct from 50× optical zoomSony 3× zoom, physical 5.8–17.4 mm F2.8–4.8, equivalent 35–105 mm. Normal focus approximately 50 cm; macro approximately 5 cm wide / 35 cm telephoto from the front of the lens. UK archive mixes normal-focus distances into its macro row; exact handbook and Hong Kong maker press resolve this
AutofocusSingle AF, DMF and manual focus; continuous AF in Advanced Sports and movie modes. Nine-point Wide, Centre and flexible spot S/M/L with Lock-on AF. Minimum AF distance from lens front approximately 1 cm wide or 240 cm telephotoMultipoint or centre AF, with distance presets; no AF illuminator, face detection or Smile Shutter in exact UK maker table. No manual focus
ShutterMechanical shutter; manual and shutter priority 30–1/4000 second, aperture priority 8–1/2000, Program 1–1/4000 and Intelligent Auto 4–1/4000Hong Kong maker table gives Auto 1/8–1/2000 second and Program auto 1–1/2000 second; Program exposure remains automatic
Burst detailApproximately 10 fps at maximum resolution for up to ten images; flash and shooting mode affect speedExact handbook: maximum three frames at 7M or 3:2, four at 5M, six at 3M, 64 at VGA and ten at 16:9; approximately 1.2-second recording interval, flash off. These finite bursts do not establish a sustained headline frame rate
Stabilisation detailOptical SteadyShot for stills; Intelligent Active movie mode combines optical and electronic correction including rotation, with a different field of view–
FlashBuilt-in flash; Multi Interface Shoe supports compatible optional flash. ISO Auto range approximately 0.5–8.5 m wide or 2.4–3.5 m telephotoHong Kong maker table: Auto ISO approximately 0.5–3.5 m wide / 0.5–2.0 m telephoto; ISO 1250 separately approximately 6.9 m wide / 3.9 m telephoto
Exposure controlsProgram, aperture priority, shutter priority, Manual and memory recall; multi-pattern, centre-weighted and spot metering, ±2 EV in 1/3 EV stepsAuto, Program auto and scene modes; no manual or aperture/shutter-priority exposure. ±2 EV in 1/3 EV steps; multi-pattern, centre-weighted or spot metering.

Video detailAVCHD 2.0 Full HD 1920 × 1080 at 60p in Japan, 28 Mbps; regional versions also use 50p. 60i/50i interlaced modes count fields rather than progressive frames. MP4 up to 1440 × 1080 at 30 fps on the Japanese version, or 25 fps on the UK version. Optical zoom operates during movies; 4K output is for still photographs, not 4K movie recording; maker single-clip limit approximately 29 minutes, with MP4 12M limited to approximately 15 minutes by its 2 GB file limitAVI Motion JPEG, 320×240 at approximately 30 fps with mono sound; approximately ten-minute maximum continuous clip. Optical zoom cannot change during movie recording. MPEG-1 and VGA claims in secondary launch coverage conflict with exact instruction guide and maker press

Release detailSony Hong Kong's 27 March 2014 release says the exact HX400V is already available. March precision retained; Sony Japan's earlier announcement sets its regional sale for 4 April 2014, not the worldwide first daySony German release planned mid-January 2008; Hong Kong release planned end-January. Contemporary Les Numériques news dated January 27 states the camera was available on retail shelves, supporting January precision without claiming the first day. That news misstates video and face/Smile detection; these features follow exact maker manuals instead. No explicit manufacturer predecessor established
Recording mediaMemory Stick Duo, PRO Duo, PRO-HG Duo and XC-HG Duo plus SD/SDHC/SDXC; micro versions require separate adaptersApproximately 22 MB internal memory; Memory Stick Duo, PRO Duo and PRO-HG Duo. PRO-HG cards operate at PRO Duo speed; optional cards are separate from the bare camera
PortsMulti/Micro USB terminal with Hi-Speed USB 2.0, micro HDMI and Multi Interface ShoeCombined USB/A/V OUT terminal for mono audio and NTSC/PAL composite video; Hi-Speed USB 2.0 explicitly confirmed in exact instruction guide and handbook. UK archive A/V omission conflicts with these manuals
Wireless connectionsIEEE 802.11b/g/n Wi-Fi at 2.4 GHz, NFC and GPS; maker launch includes GPS route logging. Original PlayMemories Mobile sharing/remote control and downloadable Camera Apps support are launch-era features, not a promise of current service availability–
Battery life detailNP-BX1; maker CIPA approximately 300 photographs with LCD or 380 with EVF. Actual movie shooting approximately 50/55 minutes or continuous movie shooting approximately 85/95 minutes for LCD/EVF respectively; these are battery claims rather than single-clip limitsTwo supplied LR6 alkaline AA batteries: approximately 100 shots / 50 minutes CIPA at 25 °C, one shot every 30 seconds, alternating zoom ends, flash every other shot and power cycle every ten. Optional NH-AA NiMH pair: approximately 440 shots / 220 minutes; these are not the supplied alkaline cells
ChargingUSB charging; maker specifies USB power supply only with optional AC-UD10 adapterSupplied alkaline cells cannot be recharged. Optional compatible NiMH cells require an external charger; optional AC-LS5K power adaptor is separate
DimensionsApproximately 129.6 × 93.2 × 114.8 mm width × height × depth from lens front to viewfinder; depth to rear monitor is 103.2 mm91.4×61.0×29.1 mm width×height×depth, excluding protrusions, in exact instruction guide
Weight detailApproximately 633 g body only, or 660 g including NP-BX1 and Memory Stick Duo140 g body only in exact UK maker archive and Hong Kong press; approximately 189 g including two batteries, wrist strap, etc. in instruction guide. Plastic body per reproduced German maker table
