To set the aperture on Zoom-Nikkor lenses having variable maximum apertures, refer to Setting Apertures on Zoom-Nikkor Lenses having Variable Maximum Apertures.
For example, when shooting with ISO 100 film, with the angle of coverage adjusted to N-35mm, selecting f/5.6 lets you take pictures of subjects at a distance of approx. 5m (16.4 ft.) away, while f/2.8 lets you take pictures of subjects approx. 10 m (32.8 ft.) away. To determine the correct aperture, use the equation and guide number table: guide number f/stop (aperture) = flash-to-subject distance (m/ft) Guide numbers (m/ft) in M mode at 20C/68F

Determining an appropriate flash shooting distance range in the TTL Auto Flash TTL mode
Camera and film speed combinations
Because the flash output is automatically controlled by the SB-22s, any Nikon camera/film speed combination can be used. Correct exposure is obtained by setting the same aperture (obtained from the aperture/shooting distance range panel) as set on the camera or lens aperture ring. Exposure compensation is easy to achieve by intentionally changing the aperture on the camera or lens aperture ring.
for after approx. 80 seconds, the SB-22s shuts off automatically and the ready-light goes out to conserve battery power. This is called the standby function. To turn the SB-22s on again after it enters the standby mode, you can lightly press the shutter release button or press the FLASH button once.
Check the aperture set on the camera or lens.
In the TTL Auto Flash mode, you can set any aperture value on the camera or lens aperture ring.
For example, when shooting a subject at a distance of 5m (16.4 ft.) using ISO 100 film with the angle of coverage adjusted to N-35mm (no wide flash adapter), 28 f/stop = (in meters) = 5.91.9 f/stop = (in feet) = approx. 5.6 16.4 Therefore f/5.6 is the correct aperture. To set the aperture on Zoom-Nikkor lenses having variable maximum apertures, refer to Setting Apertures on Zoom-Nikkor Lenses having Variable Maximum Apertures.
distance range 2 Check the shootingflash shooting distance represented by the range indicator which matches the f-number in the aperture scale window.

Ready-light comes on.

Do not use the standby function: If the SB-22s is mounted on Nikon F3-series, New FM2, FM10 or FE10 cameras. If the SB-22s is mounted on Nikon FA or FE2 cameras and the shutter speed is set to M250 or B (bulb). If the SB-22s is mounted on Nikon FG or Nikonos V cameras and the shutter speed is set to M90 or B (bulb). If the SB-22s is mounted on a Nikonos V with an optional sync cord for land use connected and the shutter speed is set to M90 or B (bulb). If the SB-22s is mounted on a Nikon FM3A camera and the shutter speed is set to B (bulb). The standby function does not work: If the SB-22s is mounted on Nikon FA or FE2 cameras with Motor Drive MD-12 attached and Remote Code MC-4A (or MC-10) is connected.

For example, selecting f/4 lets you get the flash shooting distance range from 0.9m to N 35 mm 7.0m (3 ft. to 23 ft.) with angle of coverage at OFF ON STBY FLASH READY BOUNCE N-35mm and a film speed of ISO 100. JAPAN In this case, underexposure may occur when the subject is more than 7.0 m (23 ft.) away. For other shooting distance ranges, apertures, and ISO film speeds, refer to the table below.

Setting Apertures on Zoom-Nikkor Lenses having Variable Maximum Apertures
Setting the aperture using the camera aperture dial:
For example, F5, F100, F80-Series/N80-Series, F65-Series/N65-Series, F60-Series/N60, F50-Series/N50, F-401x/N5005, F-401s/N4004s, F-401/N4004, Pronea 600i/6i, D1 Series cameras with Nikkor lenses with a built-in CPU*: First set the lens to its minimum aperture (largest f-number) (except G-type Nikkor lenses**), then set the aperture on the camera using the aperture dial or button after zooming in or out to determine the focal length setting. In this way, the variable aperture will be automatically compensated by the camera.
For other camera/lens combination:
For example, F-501/ N2020, F-301/N2000, FM3A, FA, FE2, FG, Nikonos V, F3-Series, New FM2, FM10, FE10 with all other Nikkor and Nikon lenses except G-type Nikkor lenses.

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.
With exposure compensation Without exposure compensation

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.

Tips on Speedlight Care
When the wide flash adapter is set, the angle of coverage changes from N-35mm to W-28mm, and the distance scale also moves. Use a blower brush to remove dirt and dust from the SB-22s and clean it with a soft, clean cloth. Never use commercial cleaners containing thinner, benzene, or alcohol as they could damage its plastic parts. When storing the SB-22s for two weeks or longer, remove the batteries to prevent battery leakage. Also once a month, insert fresh batteries and fire the unit several times to reform its capacitor and keep the SB-22s in top working order. Finally make sure the ready-light is on, before turning the power off and removing the batteries. Keep the SB-22s away from chemicals such as camphor or naphthalene. Also avoid exposing it to magnetic waves from TVs or radios. Never store the SB-22s in the truck or glove compartment of a vehicle during the summer nor place it in front of a heater.
If the angle of the flash head is not far enough off axis from the subject, uneven illumination will result from a combination of direct and bounced flash.

2 2.5.11 16

Do not fire the flash directly into a persons eyes at close range as this may damage the retina, leading to partial or complete blindness. Keep the SB-22s out of the reach of children. This will prevent them from swallowing batteries or getting an electric shock. Do not throw used batteries into a fire. Do not short circuit, disassemble, or heat a battery; this may cause it to explode or catch on fire.
Any metering system is acceptable. For Nikon FM3A, New FM2 and FM10 cameras, manually set the shutter speed to the flash sync shutter speed or slower. For other cameras, the shutter speed is automatically set to the flash sync speed. (Or you can intentionally set the shutter speed to one slower than the flash sync speed.)

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.
