General Vivitar Zoom Thyristor 285 Information
The Vivitar 285 is the world's most classic of all flashes. It's a fully automatic system flash for use with most cameras, digital, 35mm and medium format. The Vivitar 285 is not only the world's most popular flash of all time, it is also extremely modular: you can buy all sorts of crazy and sane accesory filters, zoom filters, light modifiers, cables, sensors and battery packs and more for it.
A slightly newer model, the Vivitar 285 and today's Vivitar 285 HV, adds an integral zoom head.
It has a hot shoe, as well an included PC cord for use with any camera or shutter with a standard PC sync terminal.
I measured its sync voltage of this original 1970s sample as 267VDC, so don't use the originals on electronic cameras, many of which have sync electronics which could be zapped by this flash. Mechanical shutters and cameras are perfect for use with this flash, and newer versions have much lower trigger voltages.
Its illuminated calculator dial is a joy to use; just press the little clear button on the back, and the calculator dial lights evenly in green!
Unlike older models like the Vivitar 252, the new thyristor circuitry of the Vivitar 285 uses only the power needed for each shot, saving the rest for much faster recycle time and many more flashes unless you're near the end of the auto range, or shooting at full manual power

Looking after your camera
Use a Camera Bag
A camera bag does more than just protect the camera against scratches and dust: It keeps it safe from rain because many are waterproof on the outside.
Be Very Careful Around the LCD Screen and Camera Lens
Use only special equipment to clean your camera’s LCD screen and camera lens. Buy a special cleaning kit that includes liquid solutions, microfiber cloths and brushes that have been specially designed to clean your camera lens.
Never Leave Your Batteries in Your Camera for Too Long
Many camera batteries are now alkaline or lithium formats. If you keep your camera with the batteries inside of it in a moist area, then the batteries can get corrosive. So if you’re thinking about just putting your camera on the shelf for several months, do yourself a favor and remove them.
Turn Your Camera Off Prior to Doing Anything
Before you do anything to your camera, always keep in mind that it should be turned off first. No matter what it is—swapping lenses, changing memory cards or disconnecting or attaching cables—your camera should be turned off.
Cold and Wet Weather Can Wreak Havoc on Your Camera Body
Take your camera out only in a waterproof bag. If the weather’s unusually cold, just wrap your camera in a plastic bag that has silica desiccant packets for the reduction of moisture. It’s also a smart idea to have a soft towel with you to wipe off any moisture, just in case it should get on your camera.
Good Memory Card Care Is Good Camera Care
Only transport your memory cards inside of a protective caseMake sure the memory cards stay dust-free at all times. When removing memory cards, make sure you do so indoors or in non-dusty situations.
Make sure that you keep memory cards only in cool places. Never keep them in places where they may heat up, like dashboards or glove compartments.
Never place your memory cards close to magnetic sources. Examples of magnetic sources are things such as audio speakers, TV monitors and actual magnets.
Use a Filter to Protect Your Camera Lens
The lens of your camera is naturally fragile. As such, it’s susceptible to scratches, cracks, dents…you name it. A UV filter will not only will you give your lens a fighting chance, but you’ll also enhance the quality of your pictures.
Condensation Can Be Controlled
Condensation normally happens when you move your camera between different temperatures.
Allow your camera a chance to naturally get used to the hotter environment. Don’t place it inside a closed plastic bag when transporting it between different temperatures! Just let the camera sit in the humid temperature for a while, until condensation disappears.
If this still doesn’t get rid of all of it, you can utilize a soft cloth to wipe away any remaining moisture and marks left behind from the condensation.
