To enable you to fully enjoy and take advantage of the wide range of possibilities offered by this high-quality, precision camera, we recommend that you first read this manual carefully. Leica not only develops and manufactures highperformance products for photography, projection, observation and photographic reproduction - an additional service available to you is the Leica Akademie. For many years, this internationally famous school has been teaching photographic know-how in application-oriented seminars and training courses. [. . . ] When the wheel is pulled out, you feel distinct click stops as you turn it. If the standard eyepiece adjustment from +2 to -2 diopters is inadequate for your eyesight, additional correction lenses are available (see page 51). Focusing with the universal screen The LEICA R7 includes a universal focusing screen as standard feature. This produces a bright, high-contrast image and is suitable for photography in most of the situations that are normally encountered. When the image is out of focus, the edges and lines of the subject are discontinuous in the upper and lower semicircles of the split-image focusing screen (i. e. A ring formed by a screen of rectangular microprisms surrounds the central split wedge. When the image is out of focus, this screen appears to flicker. The outer circumference of this ring also marks the outline of the field for selective exposure metering. 34 Not For Resale ­ Free Download at http://homepage. ntlworld. com/joechan/manuals The remainder of the screen looks like a groundglass screen and is ideal for focusing telephoto lenses and for close-range photography. Caution: Before focusing, the eyepiece must be set to the user's diopter value (see p. Additional focusing screens are available as accessories. They offer optimum focusing for different conditions and can be changed easily (see p. 53). Eyepiece shutter The silicon photodiode of the exposure meter is located in the base of the LEICA R7, where it is protected from stray light. Normally, therefore, there is little likelihood of light entering the viewfinder eyepiece and affecting exposure meter readings, except when your are not using the viewfinder, e. g. for taking photographs from a tripod, when direct sunlight or bright artificial light may enter through the eyepiece. To prevent this, turn the knob of the eyepiece shutter [30] at the left to the eyepiece in the direction of the arrow. When the shutter is in place, a white triangle appears in the eyepiece. 35 Not For Resale ­ Free Download at http://homepage. ntlworld. com/joechan/manuals Using flash equipment The LEICA R7 is designed for through-the- lens flash-exposure control in conjunction with SCAcompatible (System Camera Adaption) electronic flash units fitted with an SCA 351 or 551 adapter. TTL-flash exposure metering offers many advantages in various fields of application and is essential for correctly exposed photographs with flash, e. g. in macrophotography, when using zoom lenses or long focal length lenses for portrait shots. Depending on the camera mode selected, it is possible to dosage flash intensity as fill-in flash to lighten up individual subjects (see below). TTL-flash exposure metering occurs in the fullfield integral mode and uses a separate silicon photodiode, well protected from stray light, in the base of the camera next to the photocell for selective/integral exposure metering. [. . . ] Manual settings from 4s to 1/2000 s in half values. Mechanical shutter-speed settings: "100 " = 1/100s flash synchronization, or in case of battery failure. "B" for time exposures of any length. (Exposures in "B"-setting electronically controlled when using drive in 4 fps setting) Mirror system: Semi-transparent, vacuum coated swing mirror, coated with 17 layers, reflects 70% and transmits 30% light, backed by Fresnel reflector (1345 micro-reflectors) to concentrate light on exposure meter's photocell.
