MiNT Self(ie) Timer
This is something MiNT designed in their free time, as a token of appreciation for everyone's continued support. It's a self-timer for all folding Polaroid SX-70s. Self(ie) fits perfectly on any SX-70 including Sonar, SLR680 and SLR670 series. You can choose between 10, 5 or 3 seconds. And it's got an LED to tell you when the time is up.
The Self(ie) Timer can be used for self-portraits or group shots that include the photographer. Simply plug it into your SX-70. This reduces the camera-shake caused by pressing the shutter button.
Batteries included and installed.
