Selling a Vivitar Auto 2600 electronic flash, a classic all-purpose unit for older film cameras. Hot shoe mount with a sync port, auto-thyristor exposure control, and the ASA/aperture calculator dial on the back for setting exposures. Specs: Guide number 60 (ISO 100/ft) Auto exposure with two aperture settings Runs on 4 AA batteries Hot shoe mount plus PC sync port Auto-off power saving Condition: untested, sold as is. I have not put batteries in to confirm it fires, so it's priced accordingly. Normal cosmetic wear and some marks on the body as shown in the photos. Important: this is a vintage film-era flash with higher trigger voltage. It's intended for older film cameras and should not be mounted on a modern digital camera, since the voltage can damage newer electronics. Please only buy if you're using it with film gear. $10. Pickup only. Please reach out by email only, I don't coordinate by text or phone.
