123Technical data Type of camera Compact 35mm rangefinder system camerawith electronically controlled shutter and 2 mechanically controlled shutter speeds.Lens mount Leica M-bayonet.Lens system Leica M-lenses from 21–135mm.Exposure metering Exposure metering through the lens (TTL),selectively with working aperture. Center-weighted integral TTLmetering for flash exposure using system-compatible SCA 3000standard flash units.Metering principle The light reflected from a measuring fieldin the center of the 1st shutter curtain is measured. The measur-ing field has a diameter of 12mm and is therefore equal to approx. 13% of the total negative format or in the viewfinder to approx. 2/3 of the short side of the valid viewfinder frame.Metering range (at ISO 100/21°) From 0.03cd/m2to 125000cd/m2at room temperature, normal humidity and aperture 1.0. For ISO100/21° this corresponds to EV-2 to 20 or f/1.0 and 4s to f/ 32and 1/1000s. Flashing of the left-hand triangular LED in the viewfinder indicates working in conditions of low light.Photocell for ambient light (continuous light metering) Siliconphotodiode with condensor lens to the top left behind the camera bayonet.Film speed setting range Optionally automatic setting for DX-coded films from ISO 25/15° to ISO 5000/38° or manualsetting from ISO 6/9° to ISO 6400/39°. Additional setting of anexposure compensation (± 2 EV) makes it possible to use filmswith speeds from ISO 1.5/3° to ISO 25000/45°.Exposure mode Optionally automatic control of shutter speed– with corresponding digital display – with manual aperture selection (aperture priority mode), or manual setting of shutterspeed and aperture and compensation using LED light balance.Flash exposure controlFlash unit socket Accessory shoe with central- and controlcontacts or standard flash connection socket.Synchronisation Optionally with the 1st or 2nd shutter curtain(with appropriate flash unit and SCA-3502 adapter).Flash synchronising speed =1/50s; automatic setting with" AUTO ”; slower shutter speeds can be used with manual setting;faster shutter speeds (1/250s, 1/500s, 1/1000s) can be usedwith manual setting if attached flash unit has the "High Speed Synchronisation” function and an SCA-3502 adapter is used.Flash exposure metering (with SCA-3501/3502 adapter or SCA-3000 standard flash unit, e.g. LEICA SF20): TTL control with center-weighted integral metering.Flash photocell Silicon photodiode with condensor lens to thebottom right behind the camera bayonet.Film speed range for TTL flash exposure metering ISO12/12° to 3200/36°Flash exposure compensation ±3 1/3EV in 1/3EV steps canbe set on SCA-3501/3502 adapter. On the LEICA SF20/SF24D,±3 EV in 1/3EV steps can be set or from 0 to –3 EV in 1 EV stepswith computer control.Displays in flash mode Ready to use Constant illumination of flash symbol LED in the viewfinder.Success check Continued illumination or temporary rapid flashing of the LED after exposure, underexposure shown by theLED temporarily going out.
