Minolta produced numerous rangefinder cameras (see e.g. this link). The most popular models are found in the Hi-Matic series, which was started in the 1962 with the Hi-Matic and continued until the 1980s, the Hi-Matic 7sII being the latest and most advanced model.

The Hi-matic 11 is a sucessor model of the Hi-Matic 7s (in between came the Hi-Matic 9) and is based on the same rather large housing. On the front cover it says "Super 3 Circuit", which sounds impressing but I have no idea what it means. It is equipped with a fast f/1.7 45 mm Rokkor lens. The camera can be operated in semi-automatic time priority or fully automatic mode. It cannot be operated fully manual.

The viewfinder is identical to that of the Hi-Matic 7s, except that the aperture values are shown (replacing of EV values in the 7s finder). And it has an additional nice feature: Through a small extra window you can see the selected exposure time on the lens barrel. As for the Hi-Matic 7s, the focusing mechanism works via a horizontal tilt of the front lens of the finder system.

The Hi-Matic 11 takes one PX625 1.35V mercury battery. It can can be replaced with the equally sized PX625A Alkali battery, which, however, provides a voltage of 1.5 V. Consequences for the meter reading have, at least for fresh batteries, to be accounted for.
