User manual NIKON SB-29

[. . . ] Major features of the SB-29 The SB-29 consists of the main unit and controller. Attach the main unit to the lens or to the front of the controller to take effective close-up flash photographs. With the SB-29, you can shoot ultra close-up photographs of flowers, insects or small objects in the TTL auto flash mode. Installing the batteries Attaching the controller and main unit The SB-29 consists of the controller and main unit. Attach the controller to the camera and the main unit to the lens or to the front of the controller. ·When attaching the SB-29 to the camera or lens, be sure to turn off the SB-29. 1 Setinthe SB-29's power switch to OFF, itthen slide down the battery chamber lid the direction of the arrow and lift off. Attaching the main unit to the lens With the lens in normal position the lens' filter 1 Depending onto the lens. [. . . ] *3 Total number of flashes when fired at full manual output with an interval of 30 seconds between flashes. ·Number of flashes are greater in TTL Auto Flash and M1/4 flash output modes. Flash mode selector TTL, M, or M1/4 mode selectable Ready-light ·Lights up when SB-29 is recycled and ready to fire. ·Blinks for 3 seconds when flash fires at its maximum output, indicating light may have been insufficient (in TTL mode). 3 ·Determine an appropriate aperture by referring to the "Aperture/reproduction Set the aperture on the lens or camera. ratio panel" on the back of the SB-29 controller. (Refer to "Determining a proper flash shooting distance range. ") Overexposure warning indicator LED Lights up for approx. after shooting to indicate that the picture may have been overexposed. come on before taking the 4 Wait for the SB-29's ready-lightintothe viewfinder of your camera. ·You can also use the ready-light ·If the ready-light on the SB-29 or in the viewfinder blinks for approx. 3 seconds after shooting, this indicates the light may have been insufficient for correct exposure. In this case, use a wider aperture (smaller f-number) and reshoot. ·If the SB-29's overexposure warning indicator LED lights up for approx. 4 seconds after shooting, this indicates the picture may have been overexposed. In this case, use a smaller aperture (larger f-number) and reshoot. Aperture to set on the lens and effective f-number Effective f-numbers of macro lenses such as Micro-Nikkor lenses vary and the brightness of images on the film decrease when the reproduction ratio increases. The relationship between the reproduction ratio and the effective f-number is: Fe = F (1 + M) where Fe = Effective f-number (actual lens speed) F = Aperture to set on the lens M = Reproduction ratio ·For example, to obtain a 1:1 (life-size) reproduction ratio at an aperture of f/8 set on the lens, Fe = 8 (1 + 1) = 16. The effective f-number is 16 which is two stops darker. Effective f-numbers are displayed on the SB-29's "Aperture/reproduction ratio panel. " To obtain the correct exposure in TTL auto flash operation, proceed as follows: ·The aperture value appearing on the LCD panel or in camera's viewfinder is the effective f-number when a Nikkor lens with a built-in CPU is mounted on the camera. ·When a Nikkor lens without a built-in CPU is mounted or no aperture value is displayed in the viewfinder calculate the effective f-number using the above equation after setting the aperture on the lens. Built-in light reducer Sets the ratio of the brightness of the right flash module to the left one (or vice versa) to 1:4. FLASH button ·Performs test firing for correct exposure determination. ·Can turn the SB-29 on again after the unit enters standby mode. Flash duration (approx. ) At full flash output: 1/1400 sec. with single flash module) At 1/4 flash output: 1/5500 sec. with single flash module) ·Refer to "Optional accessories" for sync or remote cords. ·Read each product's instruction manual for details on connections. Modeling illuminator Lights up for approx. (when both modules are fired), if flash is completely recycled. 40 Hz. Multiple flash operation using the Wireless Slave Flash Controller SU-4: ·TTL or Manual multiple flash operation is possible by using the camera's built-in Speedlight or a Speedlight mounted on the camera's hot shoe as the master flash unit, and one or more Speedlights mounted on Wireless Slave Flash Controllers SU-4 as the slave flash units. ·The SU-4's built-in light sensor not only detects when the master flash unit fires to trigger the slave flash unit, but also controls the flash duration of the slave flash unit in sync with the master flash unit. [. . . ] Do not recharge NiCd or Ni-MH batteries with their terminals reversed in the charger or before the batteries have cooled off sufficiently, as this may cause them to leak corrosive liquids, become hot, catch on fire, or explode. ·Non-rechargeable batteries such as zinc-carbon, alkaline-manganese and lithium batteries should never be charged in a battery charger as they may become hot, catch on fire, explode or leak corrosive liquids. ·Always use the batteries specified in this instruction manual. Using other batteries may cause them to become hot or catch on fire. Notes on Batteries ·Battery power tends to weaken as the temperature drops. [. . . ]
