My Buying Guide on Vivitar Auto Thyristor 2800

When I first decided to invest in a reliable flash unit for my photography, the Vivitar Auto Thyristor 2800 caught my attention. After using it extensively, I wanted to share my experience and some key points to consider if you’re thinking about buying this flash.

Understanding the Vivitar Auto Thyristor 2800

The Vivitar Auto Thyristor 2800 is a classic external flash known for its dependable performance and affordability. It’s designed to work with a variety of cameras, offering automatic flash control through its thyristor sensor. From my experience, it’s a great option for both beginners and hobbyists who want consistent lighting without breaking the bank.

Key Features That Impressed Me

  • Thyristor Auto Sensor: One feature I really appreciated was the auto thyristor sensor, which automatically adjusts the flash output based on the distance to the subject. This helped me get well-exposed photos without manual adjustments.
  • Guide Number: The 2800 in the name refers to the guide number, which is about 28 at ISO 100. This means it has enough power for most indoor and moderate outdoor shots.
  • Zoom Head: The flash head zooms to match the focal length of your lens, which I found handy for more precise lighting.
  • Compatibility: It works well with many camera models using a standard hot shoe, making it versatile if you switch camera bodies.

What I Considered Before Buying

  • Camera Compatibility: I made sure my camera supported external flashes with a standard hot shoe. Some modern cameras might require adapters or have specific flash requirements.
  • Power Source: The flash uses AA batteries. I decided to invest in rechargeable NiMH batteries, as this flash can drain standard alkalines quickly during heavy use.
  • Size and Weight: It’s a bit bulkier compared to modern compact flashes, so I checked that it wouldn’t feel too heavy on my camera rig. For me, the extra size was a fair trade for its power.

Pros and Cons Based on My Use

Pros:

  • Affordable and easy to find used or new.
  • Reliable auto exposure with thyristor technology.
  • Good power for most shooting situations.
  • Simple controls, great for beginners.

Cons:

  • No TTL metering; exposure is controlled by the thyristor sensor, which might not be perfect in all scenarios.
  • Slightly bulky compared to modern flashes.
  • Requires manual zoom adjustment if your lens changes focal lengths frequently.

Tips for Getting the Best Out of the Vivitar Auto Thyristor 2800

  • Always check your batteries before a shoot; I keep a spare set handy.
  • Use a diffuser or bounce the flash off walls or ceilings to soften harsh shadows, as the flash is quite powerful.
  • Practice positioning the flash at different angles to understand how the thyristor sensor reacts.
  • If you shoot in bright daylight, consider using ND filters or adjusting your camera settings since the flash power is fixed.

Final Thoughts

Buying the Vivitar Auto Thyristor 2800 was a solid choice for me when I wanted an affordable, reliable flash without complicated features. While it’s not the newest model on the market, its simplicity and power make it a dependable tool for many photographers. If you appreciate manual control paired with automatic flash output adjustment, this flash might be just what you need.
