If the ready-light 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) or move closer to the subject. You can also check if the subject will receive the correct exposure by test firing the SB-22s. Refer to Checking the Correct Exposure.
For example, if the flash-to-subject distance is 5m (16.4 ft.), set the flash mode selector to A4 (f/2.8), A3 (f/4) or A2 (f/5.6) when using ISO 100 film with the angle of coverage adjusted to N-35mm. Underexposure may occur if A1 (f/8) is selected. Using an aperture wider than the maximum aperture of the lens in use is not recommended. To determine the correct flash shooting distance range and aperture, refer to Checking the Correct Exposure.

In Non-TTL Auto Flash A mode, you can N 35 mm select A1, A2, A3, or A4 only. OFF ON STBY FLASH READY BOUNCE For example, when shooting a subject located JAPAN at 5m (16.4 ft.) with the angle of coverage at N-35mm and a film speed of ISO 100, the available apertures are f/2.8, f/4 or f/5.6. Selecting f/2.8 lets you take pictures of subjects approx. 1.3m to 10.0m (4.3 ft. to 32.8 ft.) away from the SB-22s. If you choose f/4, you can take pictures of subjects approx. 0.9m to 7.0m (3 ft. to 23 ft.) Underexposure may occur when the subject is more than 10m (32.8 ft.) away when f/2.8 is selected, or more than 7m (23 ft.) away when f/4 is selected. For other shooting distance ranges, apertures, and ISO film speeds, refer to the table below. Available apertures possible at A1 to A4 vary according to the setting of the film speed (ISO) scale. Correct exposures cannot be obtained if the same aperture as indicated by the illuminated f-number is not set on your camera or lens aperture ring.

For example, F4-Series, F90X/ N90s, F90-Series/ N90, F70-Series/ N70, F-801s/ N8008s, F-801/N8008, F-601/N6006, F-601M / N6000 cameras with Nikkor lenses with a built-in CPU* Check and set the aperture on the LCD panel after zooming in or out to determine the focal length setting. In this way, the variable aperture will be automatically compensated by the camera.
*Nikkor lenses with a built-in CPU incorporate CPU contacts. (See the figure on the right.) **G-type Nikkor lenses have no aperture ring. The aperture should therefore be selected from the camera body. Unlike other CPU Nikkor lenses, the aperture does not need to be set to its minimum. CPU contacts
Align the aperture ring between the green and yellow aperture indexes after zooming in or out to determine the focal length setting. If the zoom lens has a maximum aperture difference of approx. 1 or more f/stop between the longest and shortest focal length positions (see the figures below), align the aperture ring with the green aperture index for a wide setting, and align the aperture with the yellow aperture index for a telephoto setting. For intermediate focal length settings, set the aperture ring somewhere between the green and yellow aperture indexes depending on the focal length in use.

Exposure Compensation in Flash Photography
Some plus compensation may be necessary when the background includes a mirror, white wall, or other highly reflective surface. Otherwise, underexposed pictures might occur. Similarly, some minus compensation may be required when the background is dark or includes subjects of low reflectivity to prevent overexposed pictures. In these cases, making exposure compensation is recommended to obtain the correct exposure. Normally, exposure compensation within the range of 2 to +1 steps is recommended.

Exposure compensation in TTL Auto Flash TTL mode
Make exposure compensation on the camera to match the shooting situation. Consult the instruction manual provided with your camera for specific information on procedures for exposure compensation. When shooting a subject containing highly reflective surfaces, use some plus compensation. When the background is very dark, or the subject is in deep shadows, use some minus compensation.
Determining whether the subject will receive the correct exposure in TTL and Non-TTL Auto Flash modes by test firing the SB-22s.
1 Follow the same procedures as in TTL Auto Flash TTL or Non-TTL Auto Flash A mode.
In TTL mode, set the flash mode selector to either A1, A2, A3 or A4 to line up the same aperture set on the camera or lens aperture ring with that indicated on the aperture/shooting distance range panel. If the apertures are out of the range of available apertures possible at A1 to A4, the correct exposure cannot be determined before shooting.
Conditions necessary to activate the AF assist illuminator LED:
The subject must be sufficiently dark. AF Nikkor lenses must be used. Lenses from 24mm (35mm for F-501/N2020**) to 105mm are recommended. The cameras autofocus mode is set to Single Servo Autofocus (Set cameras focus mode selector to AF for F50-series/N50*, and A for F-401x/N5005*, F-401s/N4004s* and F-401/N4004*).

Bounce Flash

When taking pictures indoors, direct flash often causes harsh, unattractive shadows on the subject or background. By bouncing the light off the ceiling or walls, you can soften the shadows and produce more natural-looking portraits.
Bounce flash using diffused light Normal flash using direct flash

Close-Up Flash

In TTL Auto Flash TTL mode, when shooting subjects such as flowers or insects closer than 0.6m (2 ft), use your SB-22s off camera and utilize its built-in wide flash adapter to take close-up pictures with flash.
Setting the Built-In Wide Flash Adapter
The SB-22s comes with a wide flash adapter to increase the angle of coverage to match a 28mm lens. The guide number is reduced from 28 to 20 (ISO 100, meters) when the built-in wide flash adapter is used.

Troubleshooting

Warning indicator Cause POWER switch is turned OFF. Batteries are not installed correctly. Ready-light does not come on. Battery power is weak. Standby function is in operation. Contacts in the battery chamber (SB-22s) or battery electrodes are corroded. Ready-light blinks for approx. 3 sec. after shooting. Subject is out of the flash shooting distance range. Batteries are exhausted. Reference/remedy Preparation (4) Preparation (2) The Ready-Light Preparation (4) Clean the contacts or electrodes.

WARNING

Never attempt to disassemble or repair the SB-22s yourself as this may cause electric shock or cause the unit to malfunction, leading to possible injury. Do not drop the SB-22s or hit it against a hard surface. If dropped, do not touch the metal portions inside the flash, because they could cause electric shock or injury. Remove the batteries and take the unit to your local Nikon dealer for repair. If you detect heat, smoke, or the smell of burning, stop operation immediately and remove the batteries to prevent the unit from catching on fire or burning. Let the SB-22s cool down sufficiently before removing batteries. Then take the unit to your local Nikon dealer for repair. The SB-22s should not be exposed to rain or saltwater. If water gets inside the SB-22s, this can cause electric shock or cause the unit to catch on fire. Also never touch the flash unit with wet hands. Do not operate the SB-22s in an environment containing a combustible gas, as this may cause the unit to catch on fire or result in an explosion. Keep batteries out of the reach of children. If a battery is accidentally swallowed, call a doctor immediately. When replacing batteries, replace all four batteries at the same time, do not mix battery types or brands, do not use old with new batteries, and never reverse the polarity of the batteries when installing. Otherwise, the batteries may catch on fire or explode, due the possible leakage of corrosive liquids. In the event that corrosive liquids do seep from the batteries, avoid touching the liquids. Certain types of batteries contain strong alkaline liquids which can cause chemical burns. If the alkaline liquids stick to your skin or clothes, wash immediately with running water.

Notes on Batteries

Handling batteries Battery power tends to weaken as the temperature drops. At low temperatures, the number of flashes decrease and recycling time is longer. NiCd, Ni-MH and lithium batteries feature greater efficiency at low temperatures, usable as low as 20C (4F). Alkaline-manganese and zinc-carbon batteries are not recommended as their performance become noticeably degraded at 10C (14 F) for alkalinemanganese and 0C (32F) for zinc-carbon batteries. In either case, battery performance may differ with each brand, due to modification in specifications or improvement in performance. Using lithium batteries Lithium batteries incorporate internal safety switches. When they become hot, their safety circuits are activated, cutting off power. Battery power will recover if you stop using them, allowing their temperature to return to normal. Using rechargeable NiCd and Ni-MH batteries Overcharging and excessive use may shorten battery life. Always make certain to turn the SB-22s off when not in use. Because flash consumes a large amount of battery power, rechargeable batteries may not operate properly before reaching the end of their stated life-span or the number of charging/discharging as specified by the battery manufacturer.
Always follow the warning instructions printed on batteries to prevent them from becoming hot, leaking corrosive liquids, catching on fire, or exploding. When recharging NiCd or Ni-MH batteries, be sure to use the battery charger specified by the battery maker and read the instructions thoroughly. 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 not be charged in a battery charger as they may become hot, catch on fire, explode, or leak corrosive liquids.

If the ready-light 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 or reduce the distance between the subject and the SB-22s, where the distance is measured from the flash to the bounce surface and back again to the subject. You can also check if the subject will receive the correct exposure by test firing the SB-22s. Refer to Checking the Correct Exposure.
For example, with a subject 0.5m (1.6 ft.) away from the SB-22ss flash head using ISO 100 film and the wide flash adapter in place, the suggested aperture is: 3 0.5 9.8 f/stop 1.6 f/stop (in meters) = 6 (in feet) = approx. 6
3 Return the flash head to its original position
Therefore, you should use f/6 or smaller (larger f-number), such as f/8, f/11 or f/16.
When shooting subjects closer than 1 m (3.3 ft.)
Tilt the flash head down to the -7 position when shooting subjects 1 m (approx. 3.3 ft.) or closer to give sufficient light to the subject with the SB-22s mounted on camera. The BOUNCE indicator LED blinks when the flash head is tilted down to -7. Use of the wide flash adapter is recommended.
the 6 Wait fortakingready-light to come on and make sure the subject is in focus before the picture.
If the ready-light 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) or move closer to the subject.
