Features of the Hi-Matic 7s

The Hi-Matic 7s and Hi-Matic 9 followed the H-Matic 7 in 1966, and were improved versions of the 7. The 7s came with the Contrast Light Compensator (CLC) metering system, but how it works in Hi-Matic cameras is unclear. The 7s also added a hot shoe and Safe Load System (SLS) indicator to show that film was loaded and being transported properly. Additional differences between the 7 and 7s included rangefinder windows changing from a contrasting 'pink and green' tint to 'yellow and blue'; the carrying strap lugs moving up to the side and given a more rounded shape; and the end of the lens barrel being black rather than the brushed aluminium of the 7. The 7s also came in a black version.

Evaluation

Modern Photography evaluated the Hi-Matic 7s in 1967 after its release. In general they noted that it operated similarly to the Hi-Matic 7. They found that CLC meter was within 1/2 stop of their test reference, and field tests with transparencies were well exposed despite a variety of light and contrast. They also liked that the meter could be switched off to prevent battery drain, and they liked the SLS indicator, which not only showed that the film had been loaded correctly but also tracked film usage. Because the lens of the 7s was the same as the 7, Modern Photography did no lens test of the 7s, and simply repeated the lens test results of the 7.
