Technical data from Leica factory web site.
Issued in 2006, the LEICA M8 / LEICA M8.2
Catalogue number :
M8 camera (10702 silver or 10701 black), M8.2 camera (10712 silver or 10711
black),
Compact digital viewfinder system camera for professional use with Leica M
lenses. Microprocessor-controlled metal blade focal plane shutter.
Low-noise CCD sensor specially optimized for the requirements of the M lens
system. Pixels: 10.3 million. Dimensions:18 mm x 27 mm. Extension factor: 1.33
x. Aspect ratio 3:2. Coverglass thickness 0.5 mm, full suppression of infrared
light by additional UV/IR filter. Moiré filter: no, but full exploitation of the
lens capabilities by Moiré fringe detection and elimination by digital signal
processing. Manual setting from ISO 160/23° to ISO 2500/35°.
LEICA M8.2: additional automatic setting
with free choice of ISO range.
Viewfinder principle Large bright-line frame viewfinder with automatic parallax
compensation. Viewfinder optics with reduced sensitivity to stray light and
optimum visibility of the bright-line frame in all lighting situations. Eyepiece
Matched to –0.5 dpt. Correction lenses from –3 to +3 dpt available. Image
framing By display of two brightline frames at a time: for 24 and 35 mm or for
28 and 90 mm or for 50 and 75 mm. Display selection automatically matches the
lens in use. 100% of the sensor format is covered at 0.7 m (LEICA M8.2: 2 m).
Frame selector Displays pairs of frames manually to simulate any focal length.
Parallax compensation The horizontal and vertical difference between viewfinder
and lens is compensated appropriately for the focus setting, i.e. the
bright-line frame of the viewfinder automatically coincides with the subject
area as seen from the lens. Magnification 0.68 x (for all lenses). Wide-base
rangefinder Combination of split- and superimposed-image rangefinder shown as a
bright field in the center of the viewfinder image. Effective measuring base
47.1 mm (mechanical measuring base 69.25 mm x viewfinder magnification 0.68 x).
Lens mount Leica M bayonet with additional optical sensing for identification of
all 6-bit coded lenses.
Lens system Current 6-bit coded Leica M lenses of 16 - 90 mm focal length. All
Leica M lenses of 21–90 mm focal length produced since the year 1954 can be
used, even if lacking the 6-bit coding. Virtually all lenses can be retrofitted
with 6-bit coding. 6-bit functions Lens-dependent reduction of edge shadowing
originating in the system. Identification of the lens information within the
image file to facilitate digital archiving. Adjustment of the flash reflector
when using motor zoom flash devices. Auto slow sync. function in aperture
priority mode. Compensation of color shifts through the use of UV/IR filters.
Aperture priority mode (Auto) Automatic determination of the correct shutter
speed with manual apertue preselection and corresponding viewfinder display.
Manual exposure control Free selection of shutter speed and aperture – can be
visually checked using the exposure control in the camera seen by LED light
balance in the viewfinder.
“S” setting of shutter speed dial =
automatic control of exposure time, ISO speed and white balance. Menus reduced
to essential functions, hints on aperture and focus settings are displayed when
the Info key is pressed.
S Single picture, pressing the shutter
release once per picture. C Continuous succession of pictures with 2 pictures
per second and 10 pictures in the sequence. Auto-release Selectable with 2 sec.
and 12 sec. delay time – visualization of the countdown by an LED visible from
the front of the camera in the viewfinder window.
For illustration two M8, in black and silver chrome, with respectives SUMMICRON-M 2/35mm ASPH. lenses, hand grip bases and soft release buttons on their original carton boxes and instructions for use booklet.

Camera front Lens mount; frame selector. Top Main switch (LEICA M8.2: more
pronounced detent mechanism to prevent
inadvertent switching) and shutter
release; shutter speed dial, LCD status display: display of remaining exposures
and battery capacity. Back 2.5“ color monitor (LEICA M8.2: scratch-resistant
sapphire coverglass), dial for navigation in the menu & magnifier function
in 4 steps; 4-way direction pad for navigation in the menu & in picture details;
menu button; play button; delete button; protect button; info button. Base
Lockable base plate protects the rechargeable battery and the SD memory card
against dust and moisture. 2.5“ large bright LC display with a resolution of
about 230,000 pixels for viewing pictures and for menu settings.
(LEICA M8.2: scratch-resistant sapphire coverglass).
Brightness control in 5 stages. Checking
options after taking the picture: general quality assessment, checking the
exposure by means of a RGB tonal value histogram with identification of bright
picture areas lacking detail (can also be used when zooming in), checking the
focal plane, display of the quality parameter settings and the focal length of
the lens (when used with current 6-bit coded lenses). Picture view sizes
miniatures, 4 miniatures, full picture display and enlargement in four stages up
to 100% view (1 sensor pixel = 1 display pixel).
By pressing the set button, the following parameters relevant to the picture can
be selected and changed in the picture parameter menu: user profile, sensor
speed, manual exposure correction, white balance, image data format, picture
resolution. By pressing the menu button, parameters such as the color monitor
contrast or the color space can be set in the main menu. Menu languages German,
English, French, Spanish, Italian, Japanese, Chinese.

adjust the exposure. The LED flashes as a warning that the metering range is
overshot or undershot.
(LEICA M8.2: In “S” mode: red dot to
indicate correct exposure, left arrow to warn against camera shake, right arrow
to warn against overexposure). Heavily
center-weighted TTL exposure metering with pre-set working aperture. Metering
principle Light reflected from a white strip in the centre of the metal blade
focal plane shutter. Metering range EV0 to EV20 at 20°C room temperature,
aperture 1.0 and ISO 160/23°. Metering cell Silicon photodiode with collection
lens positioned at the center of the lower edge of the camera base. Principle
Using an extremely short calibration pre-flash fired immediately before the
exposure, the exact power requirement for the main flash is determined.
Connection M-TTL guide number control with calibration pre-flash via accessory
shoe SCA 3502 (version M4) or with Leica flash SF24D. Flash synchronization time
1/250 sec.
(LEICA M8.2: 1/180 sec.)
synchronization permits creative open aperture
photography even in bright ambient light.
Manual Flash synchronization times from B (bulb) down to 1/250 sec. (LEICA
M8.2: 1/180 sec.) Aperture priority mode Auto Slow Sync: automatic extension
of the longest flash time, using the rule of thumb 1/focal length in seconds.
(only with 6-bit coded lenses). Choice of long flash synchronization times up to
e.g. 1/8 sec. for balanced flash when taking available light pictures in
aperture priority mode. Synchronization flash firing time Firing optionally at
the 1st or 2nd shutter point (with appropriate flash device such as the LEICA
SF24D or when using the SCA-3502 adapter). Flash exposure correction ±3 1/3 EV
in 1/3 EV-Stufen stages adjustable at the SCA-3501/3502 adapter.
Settable at the LEICA SF 24D ± 3EV in 1/3 EV stages, or from 0 to –3 EV in 1EV
stages when using computer control.

action.

M8.2: 1/4000 s). With manual setting from 4 s down to 1/8000 s (LEICA
M8.2: 1/4000 s) in half steps. B for long exposures of any length.
