If you thread the ribbon in the battery chamber under the batteries beforehand when inserting the batteries, you can remove the batteries easily by pulling the ribbon when removing the batteries. 6 Types of Batteries This flash unit uses four AA batteries of the same type, as shown below. Alkaline battery (LR6) Lithium battery (FR6) Nickel-Metal Hydride battery (Ni-MH) (Nickel manganese (Ni-Mn) and nickel cadmium (Ni-Cd) batteries cannot be used. ) For information about recycling times and total number of flashes, refer to "Specifications" on page 20. If the ready lamp does not light up when you turn on the power (page 8), the batteries may be exhausted or not inserted correctly. Verify the orientation of the batteries or, if the indicators and ready lamp still do not light up, replace them with new batteries. If charging time takes more than 20 seconds, the batteries are exhausted and should be replaced with new batteries. If you let the flash unit discharge successively using lithium batteries, the batteries will overheat, activating a safety circuit that temporarily disables the flash unit. Measure the distance to the subject (between the AF200FG and subject) and determine the aperture value using the following procedure. varies depending on the ISO sensitivity. Refer to the table on page 14. ) 4 5 Set the lens aperture to the calculated value. Then take a picture. 13 Approximate flash distance in Manual flash Flash ISO Coverage sensitivity Angle Normal 100 With the wideangle panel Normal 200 With the wideangle panel Normal 400 With the wideangle panel Normal 800 With the wideangle panel Normal 1600 With the wideangle panel Normal 3200 With the wideangle panel * Aperture (F value) GN 20 15 28 21 40 30 57 42 80 60 113 85 1. 4 14. 3 10. 7 20. 0 15. 0 28. 6 21. 4 40. 7 30. 0 57. 1 42. 9 80. 7 60. 7 2 10. 0 7. 5 14. 0 10. 5 20. 0 15. 0 28. 5 21. 0 40. 0 30. 0 56. 5 42. 5 2. 8 7. 1 5. 4 10. 0 7. 5 14. 3 10. 7 20. 4 15. 0 28. 6 21. 4 40. 4 30. 4 4 5. 0 3. 8 7. 0 5. 3 10. 0 7. 5 14. 3 10. 5 20. 0 15. 0 28. 3 21. 3 5. 6 3. 6 2. 7 5. 0 3. 8 7. 1 5. 4 10. 2 7. 5 14. 3 10. 7 20. 2 15. 2 8 2. 5 1. 9 3. 5 2. 6 5. 0 3. 8 7. 1 5. 3 10. 0 7. 5 14. 1 10. 6 11 1. 8 1. 4 2. 5 1. 9 3. 6 2. 7 5. 2 3. 8 7. 3 5. 5 10. 3 7. 7 16 1. 3 0. 9 1. 8 1. 3 2. 5 1. 9 3. 6 2. 6 5. 0 3. 8 7. 1 5. 3 22 0. 9 0. 7 1. 3 1. 0 1. 8 1. 4 2. 6 1. 9 3. 6 2. 7 5. 1 3. 9 (Unit: m) The appropriate shooting distance (distance at which the appropriate exposure is available) is determined based on the combination of the ISO sensitivity setting and the aperture value on the camera when the mode dial is set to (FULL). (The values in "Wide Panel" line indicate the distance when the wide-angle panel is used. ) Note that the minimum range that will give correct exposure is 0. 7 meters. 14 Application Shooting of Auto Flash Slow-speed Sync Mode When using a normal flash to shoot a portrait, etc. , in a night or evening setting, the background will appear very dark because a normal flash light cannot sufficiently light it. However, it is possible to balance both subject and background by using the flash to properly expose the foreground subject and a slow shutter speed to expose the low light background. If your camera supports this mode, you can perform auto flash shooting. You can enjoy various auto flash shooting features in combination with the built-in flash, such as making shadows by lighting a subject from the side, illuminating the background, etc. When you use the AF200FG held away from the camera connected with an extension cord, use the optional extension cord F5P/F5P L. Connect the extension cord F5P/F5P L to the camera with the optional hot shoe adapter FG or the optional hot shoe adapter F, and connect it to the flash unit with the offcamenra shoe adapter F (refer to the diagram on the right). When you use the AF200FG in combination with the built-in flash unit of the cameras, attach the hot shoe adapter FG.
