Default flash with 7d

does anyone know if my Sunpak 383 Auto (for digital) will "talk" to a 7d?

The Sunpak 383 Super Auto Flash is a non-dedicated flash model. It's not designed to communicate with any camera as far as the settings it's using, film or digital.

But, you can trigger it using your 7D. Basically, you'd use manual exposure on the camera, setting the camera and flash to match for ISO speed and aperture, using one of the Auto modes on the flash. Make sure to set your White Balance for the flash, too (for example, using Sunny, Flash or a Kelvin temperature like 5500k), since the camera won't know you're using a non-dedicated flash and would try to set it for ambient light instead if you don't set it manually (resulting in blue photos if you tried to use Auto WB with it in typical indoor lighting, since the temperature of the light from the flash more closely matches daylight lighting).

Then, select an appropriate shutter speed to balance ambient light and light from the flash. For example, around 1/100 second is usually a good starting point for indoor photos at lower ISO speed settings with commonly used apertures. For example, something like ISO 200, 1/100 second and f/5.6 would be a common settings combination to use for flash photos indoors at if you wanted the flash to provide virtually all of the light. Increase ISO speed and/or use a wider aperture and/or use a slower shutter speed if you want more ambient light versus light from the flash.

Then, when you take a photo, the sensor on the flash will measure the reflected light during the exposure, terminating the flash burst when it sees enough light for the aperture and ISO speed being used by your camera (which you set on the flash to match your camera settings).
