User manual NIKON SB-29S

[. . . ] Major features of the SB-29s The SB-29s 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-29s, 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-29s 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-29s to the camera or lens, be sure to turn off the SB-29s. 1 Setinthe SB-29s' 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. [. . . ] Macro Adapter Ring BR-2A Used for attaching the SB-29s to lenses with a 52mm filter attachment size in the reverse position. Auto Adapter Ring BR-5 Used with the BR-2A for attaching the SB-29s to lenses with a 52mm filter attachment size in the reverse position. Auto Adapter Ring BR-6 Used for attaching the SB-29s to lenses in the reverse position. Automatic diaphragm operation is possible if the BR-6 is used with Double Release AR-10 or Double Cable Releases AR-7/AR-4. Adapter Ring UR-3 Dedicated adapter ring for the AF Micro-Nikkor 60mm lens providing AF flash operation with the main unit mounted. *1 With fresh batteries *2 Duration until the ready-light comes on after firing at full manual output. *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, M1/4, and M1/32 flash output mode. Flash mode selector TTL, M, M1/4, or M1/32 mode selectable Ready-light ·Lights up when SB-29s 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 Set the aperture on the lens or camera. to the "Aperture/reproduction ·Determine an appropriate aperture by referring ratio panel" on the back of the SB-29s 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. ready-light 4 Wait for the SB-29s' ready-light into come on before taking the picture. ·You can also use the the viewfinder of your camera. ·If the ready-light on the SB-29s 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-29s' 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-29s' "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-29s on again after the unit enters standby mode. Flash duration (approx. ) At full flash output: 1/1400 sec. [. . . ] Refer to "Exposure compensation in close-up flash photography. " 4 Turn on all flash units and make sure their standby functions are not activated. Set the flash mode of all the flash units to Manual M. 5 ·Set the mode button to M (manual) when using a slave flash unit featuring a manual wireless slave flash mode. 6 Follow the same procedures as in normal Manual flash "M" mode. Checking the lighting effects before shooting Modeling illuminator Using the modeling illuminator, you can check how the subject will be illuminated and see how the shadows will look before actually taking pictures. Set the SB-29s and your camera, then focus on the subject. Notes on Batteries ·Battery power tends to weaken as the temperature drops. [. . . ]
