My Buying Guide on Vivitar Auto Thyristor 2800

When I first decided to purchase the Vivitar Auto Thyristor 2800, I wanted to make sure I understood its features and how it would fit into my photography needs. Here’s what I learned and considered before making my choice.

Understanding What the Vivitar Auto Thyristor 2800 Is

The Vivitar Auto Thyristor 2800 is a popular external camera flash unit known for its reliable performance and ease of use. It’s designed to provide additional lighting for photography, especially useful in low-light situations or when I want to highlight my subject with more clarity.

Key Features I Looked For

  • Auto Thyristor Technology: This feature automatically controls the flash output to match the camera’s settings, which means less manual adjustment for me and more consistent lighting.
  • Power Output: With a guide number of 28 (at ISO 100), the flash is quite powerful for most amateur and semi-professional needs.
  • Compatibility: I made sure it was compatible with my camera model. The Vivitar Auto Thyristor 2800 generally works well with many 35mm film cameras and some digital models that have a standard hot shoe.
  • Adjustable Flash Head: Being able to tilt or swivel the flash head helped me bounce light off walls or ceilings for softer illumination.
  • Battery Life: It uses standard AA batteries, which are easy to find and replace, though I noted the recycle time can vary depending on the batteries used.

Why I Chose This Flash

I chose the Vivitar Auto Thyristor 2800 because it balances affordability with solid performance. The auto-thyristor feature takes a lot of guesswork out of flash photography for me, especially when I’m shooting events or portraits where lighting can change quickly.

Things to Keep in Mind Before Buying

  • Manual vs. Auto Modes: While the auto thyristor function is handy, if you want full manual control over flash output, this unit might feel limited. I recommend this flash more for beginners or those who prefer automatic settings.
  • Physical Size: It’s a bit bulkier than some modern compact flashes, so consider how much gear you want to carry.
  • Condition (if buying used): Since many units are older or found secondhand, check for any signs of wear, battery corrosion, or malfunctioning electronics.

My Final Tips

Before buying, I tested the flash with my camera to ensure proper syncing and flash exposure. Also, reading user reviews and watching demonstration videos helped me get a better sense of real-world performance. If you want a reliable, easy-to-use flash without breaking the bank, the Vivitar Auto Thyristor 2800 is worth considering.

I hope my experience helps you make an informed decision!
