Vivitar 550 FD Speedlite Auto Thyristor Flash User Manual

Model: 550 FD

1. Вовед

The Vivitar 550 FD Speedlite is an external flash unit designed to provide additional illumination for photography. This flash features an auto thyristor system for automatic exposure control and can also be operated in manual mode. It is compatible with cameras equipped with a standard hot shoe mount, including many Canon, Nikon, and Sony models. This manual provides instructions for the proper setup, operation, and maintenance of your Vivitar 550 FD Speedlite.

2. Карактеристики на производот

  • Dedicated Flash: Designed for specific camera systems to ensure proper synchronization.
  • Automatic Flash Range: Operates effectively within a range of 3 to 40 feet (approximately 0.9 to 12 meters).
  • Auto Thyristor: Automatically adjusts flash output for correct exposure based on ambient light and camera settings.
  • Bounce Functionality: Allows the flash head to be angled for indirect lighting, reducing harsh shadows.
  • Извор на енергија: Потребни се 4 AA батерии за работа.

3. Поставување

3.1. Инсталација на батерија

The Vivitar 550 FD Speedlite requires four (4) AA batteries for power. Ensure batteries are inserted with correct polarity.

  1. Locate the battery compartment cover, typically on the side or back of the flash unit.
  2. Open the cover and insert four fresh AA batteries, matching the positive (+) and negative (-) terminals as indicated inside the compartment.
  3. Добро затворете го капакот на преградата за батерии.

3.2. Монтирање на блицот на вашиот фотоапарат

The flash unit is designed to attach to a camera's standard hot shoe mount.

  1. Осигурајте се дека и фотоапаратот и блицот се исклучени.
  2. Лизнете ја ногарката за монтирање на блицот во приклучокот за топла вода на фотоапаратот.
  3. Secure the flash by rotating the locking ring or tightening the locking screw on the flash unit until it is firmly attached. The flash features a "LOCK" indicator for secure attachment.

  • Прекинувач: Го вклучува или исклучува блицот.
  • FILM SPEED / ISO Dial: Sets the film speed or ISO sensitivity.
  • AUTOMATIC / MANUAL Selector: Switches between automatic and manual flash modes.
  • f/STOP / RANGE Dial: In automatic mode, this sets the aperture and corresponding flash range. In manual mode, it may indicate guide number related settings.
  • AUTO OK Indicator: Lights up when the flash has achieved correct exposure in automatic mode.
  • READY / TEST Button: Lights up when the flash is fully charged and ready to fire. Pressing it fires a test flash.
  • C/R Switch: Likely a control for specific camera compatibility or mode.
  • TTL A1/A2/M Selector: Selects between different automatic (A1, A2) or manual (M) modes, potentially related to TTL (Through-The-Lens) metering if supported by the camera.

4.2. Automatic Mode Operation

In automatic mode, the flash's built-in thyristor sensor measures the light reflected from the subject and automatically cuts off the flash output when sufficient light has been provided for correct exposure.

  1. Attach the flash to your camera and power on both devices.
  2. Поставете го AUTOMATIC / MANUAL selector to "AUTOMATIC".
  3. Поставете го FILM SPEED / ISO dial to match your camera's ISO setting.
  4. Select an appropriate f/stop on the flash using the f/STOP / RANGE dial. This will also indicate the effective flash range. Set your camera's aperture to match this f/stop.
  5. Почекајте го READY / TEST indicator to light up, signifying the flash is charged.
  6. Take your photograph. The AUTO OK indicator will light briefly after the flash fires if the exposure was correct.

4.3. Рачен режим на работа

In manual mode, the flash fires at full power, and exposure is controlled by your camera's aperture and shutter speed settings.

  1. Attach the flash to your camera and power on both devices.
  2. Поставете го AUTOMATIC / MANUAL selector to "MANUAL".
  3. Consult the flash's guide number (usually found in a separate table or on the unit itself) to determine the correct aperture for a given distance and ISO.
  4. Set your camera's aperture and shutter speed accordingly.
  5. Почекајте го READY / TEST indicator to light up.
  6. Take your photograph.

4.4. Bounce Flash

The Vivitar 550 FD Speedlite supports bounce flash, allowing you to direct the light indirectly off a ceiling or wall for softer, more natural illumination.

  1. Gently tilt the flash head upwards or to the side to bounce the light.
  2. Adjust camera settings as needed for the increased light path and diffusion.

5. Одржување

  • Чистење: Use a soft, dry cloth to clean the exterior of the flash unit. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Do not use strong solvents or abrasive cleaners.
  • Нега на батеријата: Remove batteries if the flash will not be used for an extended period to prevent leakage and corrosion.
  • Складирање: Чувајте го блицот на ладно и суво место, подалеку од директна сончева светлина и екстремни температури.
  • Контакти за топли чевли: Одржувајте ги контактите на топлиот приклучок чисти и без остатоци за да обезбедите правилна комуникација со камерата.
