The Polaroid SX-70 is considered a classic among instant cameras. MiNT Camera has brought the SX-70's classic design into the modern era with more manual control over the camera, by creating the brown SLR670-S Instant Film Camera. The most recognizable part of the camera is the folding design, which makes it compact when collapsed, and easy to open by pulling up on the viewfinder.

The Time Machine is an external module that connects to the SLR670-S and gives full control of the camera's shutter speeds. There are also two different auto modes, A100 (SX70 film) and A600 (600 film), which are in tune with the ISO's speeds. Unplug the Time Machine and the camera will automatically go into A100 mode.

The electronics have been fully revamped and the electronic eye has been updated over that of the original SX-70 to give a proper exposure. If you find your image a little over- or under-exposed, adjust the brightness control wheel to control the exposure for another picture in the same location and lighting.

Focusing is made easy by the SLR viewfinder and the split image circle; rolling the focusing wheel to the left or the right slowly focuses what you see in the image circle. Each pack of instant film contains a built-in single-use battery to power the camera.
