The Insight Zoom 70 is a basic but very capable 35mm point-and-shoot from the early 90s. This camera is actually a rebranded Vivitar Series 1 PZ440 (the 'Insight' name was the store brand for Black's, a Canadian camera store chain).
We weren't able to locate manual but here's how Popular Photography described the camera when new:
Vivitar introduced two zooms, the 440PZ and the 470PZ. Both have 38-70mm f/4.5-7.8 lenses focusing down to 3.2 feet in 14 steps, infinity lock, and three flash modes. The 470PZ adds red-eye reduction by single preflash. List prices: $251.95 and $297.95, respectively.
This is mostly very easy to use camera but perhaps its most useful feature isn't entirely intuitive: it features a spring-loaded flash switch on the front; hold it toward the lens to 'force flash' for daylight fill light; hold it away from the lens to cancel the flash; leave it in the middle for automatic flash.
This camera requires a CR123 lithium battery (available as an option).
Condition notes The camera is in good cosmetic and functional condition. We ran film through the camera and tested all modes (we did not develop the film).
