Cobra 700AF

Check availablity: eBay.

This is a dedicated TTL flash for film. The TTL mode cannot be used on digital camera. There is no way to select manual mode, but you may still get it too fire in manual (full power only). However, you may have to isolate or remove the “extra” TTL control pins from the hot-foot to stop the camera from being confused by the legacy OTF TTL protocol.

There exists an optional accessory (700AF Pro-Grip) consisting on a hammerhead type grip and matching bracket that let you take the Cobra 700AF off camera. The AF-illuminator and hot-foot is detachable and mounts in the camera's hot-shoe when the grip is used.

To use it use the ISO slider on the back to set the flash to the same ISO as the camera, and adjust the zoom head to match the lens. Look at the scale with distances in meters and feet. The f-number next to your distance to the subject tells you what aperture to set on the camera.

Comes with a wide-angle diffuser and filter set (red, green and blue).
