For many years, this internationally famous facility has taught photographic expertise in practical seminars and training courses. It meets the needs of keen photographers, both beginners and advanced students, for special training in demanding areas of 35 mm photography, projection, and enlargement. Up-to-date, well-equipped seminar rooms are available at our Solms headquarters and at the nearby "Gut Altenberg" for these courses, which are held by experienced instructors, the content of which ranges from general photography to specialised fields of interest. [. . . ] This is particularly advantageous when wide-angle lenses, which provide a relatively large depth-of-field, are used. The larger magnification of the 0. 85-fold viewfinder with its longer base line leads to even higher accuracy: Mechanical base line x Viewfinder (distance between magnification the optical axes of the viewfinder and the rangefinder window LEICA M6 TTL with 0. 72x viewfinder 69. 25 mm LEICA M6 TTL with 0. 85x viewfinder 69. 25 mm = Effective base line Coincidence (double image) focusing In most cases, and particularly for pictures of people, the coincidence or double-image method is preferable because it requires no straight lines in the subject. Simply cover the most important part of the subject with the rangefinder field, turn the focusing ring of the lens until the double image merges to one, and recompose (if necessary) to make the exposure. Split-image focusing Approx. = 58. 9 mm x 0. 72 x 0. 85 For pictures of buildings or other subjects containing straight vertical lines, position the rangefinder field such that it is intersected by a line. Now turn the focusing ring of the lens until one continuous line is formed. In practical use, it may be advantageous to combine both methods. The rangefinder field is the bright rectangle in the centre of the viewfinder field. If you cover up the large viewfinder window (14), only the bright-line frames and the rangefinder field remain visible. The bright, sharply defined rangefinder field permits the use of either coincidence or split-image rangefinder focusing. 22 Not For Resale ­ Free Download at http://www. joe-chan. com/manuals Double image = out of focus Broken line = out of focus Coincident image = in focus 23 Continuous line = in focus Not For Resale ­ Free Download at http://www. joe-chan. com/manuals The unevenness of the white is not a result of poor manufacturing tolerances, but is due to the fact that a thick, complete coating cannot be applied to the rubberised cloth shutter curtain without the shutter performance being impaired. The irregular structure of the metering spot in no way affects the meter reading. The lens f-stop and shutter speed for correct exposure are indicated by the appearance of the light balance ( ) in the viewfinder: the exposure is correct when only the round LED in the middle comes on. Exposure metering The LEICA M6 TTL meters for exposure under ambient light through the lens at the working aperture. The reading is selective, by light reflected from a bright metering field onto a photo diode (arrow). This diode is located behind a collecting lens to the left of and above the shutter. The metering field (diameter: 12 mm, i. e. 13% of the negatives size) is situated in the centre of the first shutter curtain. Switching on the exposure meter The exposure meter is switched on by light pressure on the shutter release button (7), providing that the shutter is cocked and the shutter speed dial is not set to "B" or "OFF". When one of the two triangular LEDs or the central round LED comes on, the exposure meter is ready for operation. 24 Not For Resale ­ Free Download at http://www. joe-chan. com/manuals If finger pressure is released without the shutter being depressed, the exposure meter remains switched on for approx. 14 s and the corresponding LED(s) remain on. When the shutter is activated, the meter switches off and the LEDs in the viewfinder go out. When the shutter is not cocked, or the shutter speed dial is set to "B" or "OFF", the exposure meter remains switched off. Note: at very low levels of luminance, i. e. at the threshold of the light metering range, the LEDs may take approx. If the luminance levels fall below the working range of the exposure meter, the left-hand triangular LED flashes. Then: 1. Turn the shutter speed dial and/or the aperture ring on the lens in the direction indicated by the flashing LED until only the round LED comes on. [. . . ] Battery life: At an ambient temperature of 20°C and with the camera continuously switched on (shutter release button pressed), one set of fresh batteries lasts approx. 8 hours; at 10s per reading, this suffices for approx. Shutter: Rubberised-cloth horizontal focal-plane shutter. Mechanically controlled speeds from 1 s to 1/1000 s, in full values. [. . . ]
