FLASH MODE: TTL AUTOFLASH This flash has three flash modes: TTL, Manual (M), and Multi (Stroboscopic). In TTL mode, the camera and the flash will work together to calculate the correct exposure for the subject and the background. In this mode, multiple TTL functions are available: FEC, HSS, second curtain sync, etc.
Page 19
• When the shutter button is fully pressed, the flash will fire a preflash that the camera will use to calculate exposure and flash output the instant before the photo is taken. Display “Hi”: When the flash output value is up to the maximum value, “Hi” will be displayed and blinking for 3 seconds.
Page 20
Setting FEC: MODE ZOOM SYNC SLAVE • Press the SET Button and the flash exposure compensation amount will be highlighted on the LCD panel. • Turn the Select Dial to set the amount. - “0.3” means 1/3 step, “0.7” means 2/3 step. - To cancel the flash exposure compensation, set the amount to “+0”.

HIGH-SPEED SYNC High Speed Sync (FP flash) enables the flash to synchronize with all camera shutter speeds. This is convenient when you want to use aperture priority for fill-flash portraits. Choose the < > button: • Press the <SYNC> button to turn on high-speed sync function. •...
Page 22
SECOND-CURTAIN SYNC With a slow shutter speed, you can create a light train following the subject. The flash fires right before the shutter closes. • Set Nikon camera to Rear mode.
FLASH MODE: MANUAL FLASH The flash output is adjustable from 1/1 full power to 1/128 power in 1/3 stop increments. To obtain a correct flash exposure, use a hand-held flash meter to determine the required flash output. MODE ZOOM SYNC SLAVE MODE ZOOM...
Page 24
high-speed sync mode, the adjustable flash range is 1/16~1/1. Flash Output Range The following table makes it easier to see how the stop changes in terms of f/stop when you increase or decrease the flash output. For example, when you decrease the flash output to 1/2, 1/2-0.3, or 1/2-0.7, and then increase the flash output to more than 1/2, 1/2+0.3, 1/2+0.7, and 1/1 will be displayed.
Page 25
In the M mode, high-speed sync and second curtain sync functions can be achieved. • Optical S1 Secondary Unit Setting In M manual flash mode, press the <SLAVE> button so that this flash can function as an optic S1 secondary flash with optic sensor. With this function, the flash will fire synchronously when the main flash fires, the same effect as that by the use of radio triggers.
Page 26
• S1 and S2 optic triggering and off camera high-speed mode are only available in M manual flash mode. MULTI STROBOSCOPIC FLASH With stroboscopic flash mode, a rapid series of flashes is fired. It can be used to capture multiple images of a moving subject in a single photograph. You can set the firing frequency (number of flashes per sec.

Calculating the Shutter Speed During stroboscopic flash, the shutter remains open until the firing stops. Use the formula below to calculate the shutter speed and set it with the camera. Number of Flashes/Flash Frequency = Shutter Speed For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter speed should be at least 2 seconds.
Page 29
• Stroboscopic flash is most effective with a highly reflective subject against a dark background. • Using a tripod and a remote control is recommended. • Stroboscopic flash can be used with “bulb mode”. • If the number of flashes is displayed as “--”, the firing will continue until the shutter closes or the battery is exhausted.
• This flash can work in TTL/M/Multi/OFF flash modes when set as a master unit. As a master unit. The AP-305N can control multiple AP-305N flashes (TTL/M/Multi). As a slave unit. The AP-305N can be controlled by the following master unit models, RT-305 (M mode only), AP-305N (TTL/M/Multi).
Page 32
• Even with multiple slave units, the master unit can control all of them via wireless. • In this user manual, “master unit” refers to the camera flash on a camera and “slave unit” will be controlled by the master unit. 1.

Page 42
• Use the supplied mini stand to position the slave unit. • Before shooting, perform a test flash and test shooting. • The transmission distance might be shorter depending on the conditions such as positioning of slave units, the surrounding environment and weather conditions.
Page 43
• Auto Shooting with Two Slave Groups. • Auto Shooting with Three Slave Groups.
OTHER APPLICATIONS Auto Focus Assist Beam In poorly-lit or low-contrast shooting environments, the built-in auto focus assist beam will automatically light on to make it easier for autofocus.The beam will illuminate only when auto focus is difficult, and will cut out as soon as AF is achieved.

Bounce Flash By pointing the flash head toward a wall or ceiling, the flash will bounce off the surface before illuminating the subject. This can soften shadows behind the subject for a more natural-looking shot. This is called bounce flash. To set the bounce direction, hold the flash head and turn it to a satisfying angle.
Page 46
• If the wall or ceiling is too far away, the bounced flash might be too weak and result in underexposure. • The wall or ceiling should be a plain, white color for high reflectance. If the bounce surface is not white, a color cast may appear in the picture. Creating a Catchlight With the catchlight panel, you can create a catchlight in the subject’s eyes to add life to the facial expression.
Page 47
• Point the flash head upward by 90°. • Pull out the wide panel. The catchlight panel will come out at the same time. • Push the wide panel back in. - Push in only the wide panel. - Follow the same procedures as for bounce flash. •...
