The Sunpak GX8R is a compact ring flash head with a separate battery pack. This design makes the actual flash part much lighter in weight so there’s no strain on the lens. It’s an important thing to consider on modern autofocus cameras lenses where the construction may be a bit flimsy to be supporting a flash of the likes of the Centon MR20 or Vivitar MacroFlash 5000.
The flash was originally sold in the early 80s and comes in a case along with three lens adaptor rings to suit 49mm, 55mm and 58mm filter threads. You could attach it to smaller or larger filter threads using a step up or down ring. Care should be taken using the flash on filter threads larger than 58mm as the hole through the centre of the flash tube is just 50mm so vignetting would occur if a wide-angle is used. The ring screws into the rear of the flash on a rotating flange. This allows the flash to rotate on the lens.
Ring flash introduced by Sunpal. It is powered by an external battery pack for 4 C-type batteries that can also be used with an A.C. adaptor. The flash head has an indicator lamp, a shorting plug for test firing, and a proprietary PC sync port. It has a 52mm rotating thread disk on the rear of the flash for attaching to adapter rings and lenses. Plastic body available in black.
