ShutterMaker Japanese launch table gives automatic 8–1/1000 second range; Imaging Resource tested review describes more limited selectable automatic/Twilight behaviour, so these are published hardware limits rather than guaranteed control in every modeSony exact announcement: Auto 1/30–1/725 second; shutter priority 8–1/725 second. Exact operating instruction confirms still shutter-priority range
Stabilisation detail–No optical lens or sensor-shift stabilisation. Orientation sensor controls vertical-image playback, not camera-shake correction
FlashBuilt-in flash, approximately 0.3–2.0 m at ISO Auto; Auto, forced, off and red-eye reductionBuilt-in flash, recommended range 0.3–2.5 m, Auto/red-eye Auto/forced on/off with High/Normal/Low flash level. No external flash terminal; S70 external-flash feature does not apply

Release detailSony Japan announced planned April 2001 availability. Contemporary ASCII exact P30 test and 2 May 2001 retail price survey confirm the 2001 generation; earliest worldwide first-sale month unresolved, so year precision retained. P1 design resemblance does not establish a direct successorConservative actual-sale year 2000 supported by contemporary Digicamera June 2000 news describing current DSC-S50 retail prices in Shinjuku. Sony announcement of 2 February 2000 planned Japanese sale on 15 April; that plan alone does not establish actual first-sale day/month. No exact official predecessor relationship inferred
Recording mediaMemory Stick; 4 MB supplied, 128 MB included in maker launch table. PRO compatibility not establishedFull-size Memory Stick, supplied 4 MB. No SD slot. JPEG, TIFF and movie capacities depend on image size; approximately four 1600×1200 JPEGs on supplied card. No internal image storage published
PortsUSB mini-B, switchable NTSC/PAL VIDEO OUT minijack without audio, and DC INUSB digital I/O, monaural A/V OUT minijack with NTSC/PAL selection, and DC IN for AC-L10 adapter. Built-in microphone and speaker. No HDMI or external-flash terminal
Battery life detailTwo AA alkaline supplied; optional NP-FS11 InfoLITHIUM S. Exact shared manual continuous VGA Standard/no-flash test at 25°C, approximately 3-second intervals: alkaline 30 minutes/600 shots LCD on or60/1200 off; NP-FS11 90/1800 on or120/2400 off. Not CIPA/average-use life. Launch kit claim 2200 shots uses LCD/flash off; conditions and manual figures differNP-FM50 InfoLITHIUM rechargeable lithium-ion pack: nominal 7.2 V, 1180 mAh / 8.5 Wh. Exact pre-CIPA instruction claims approximately 2500 VGA photographs / 150 minutes at 25°C, normal LCD, fully charged battery, about five-second intervals and replacement Memory Sticks; normally charged pack 2300 / 140 minutes. This rapid single-frame test is not CIPA or a continuous burst. Separate playback and low-resolution movie runtime are not still-shooting endurance; no unqualified shot headline
ChargingOptional NP-FS11 charges in camera using optional AC-LS1 A in approximately 180 minutes from fully discharged at 25°C; AA cells are not charged in cameraIn-camera charging with supplied AC-L10 adapter through DC IN, camera switched off. Approximately 90 minutes normal charge or 150 minutes full charge for completely discharged NP-FM50. No USB charging claimed
Dimensions126×61.2×53.7 mm maximum width×height×depthExact operating instruction maximum dimensions 113×68×69 mm width×height×depth. Early Japanese announcement gives 113.1×67.8×68.8 mm excluding maximum projections
Weight detailApproximately 214 g body in exact P30/P50 maker launch table; 258 g with NP-FS11 and Memory Stick. Shared English manual gives approximately 260 g including two AA batteries, card, wrist strap and lens capExact operating instruction approximately 370 g including NP-FM50, Memory Stick, wrist strap and lens cap. Early Japanese release prints 315.6 g body / 423 g loaded in shared S50/S30 table, conflicting with later instruction loaded weight; optional body-only headline omitted rather than infer a subtraction
In the boxTwo AA alkaline batteries, 4 MB Memory Stick, USB and video cables, lens cap and cap strap, wrist strap, software CD and operating instructions; optional rechargeable battery and AC adapter sold separatelyNP-FM50 battery, AC-L10 AC adapter and power cord, USB cable, A/V cable, lens cap and cap strap, wrist strap, 4 MB Memory Stick, CD-ROM/software and operating instructions; exact shared manual distinguishes S30 video-only cable
