I bought a Minolta 16MG way back when, probably 1968. I used it for years, until I got a Rollei 35. The shots from it were ok, but nothing great. My camera linked the light meter to the shutter speed and f-stop, thus you could not change them individually. The light meter died, as most of them did, but rule of 16 allowed me to continue to use it.
The size was not great either when compared to the Rollei. Getting film was hard, and no one processed the stuff after a few years. That said, if you load your own cartridges you will have no problem. I think I still have mine someplace, but I have not used since the early 80's, so I doubt that it even works anymore. Look on ebay, they are there, some priced really stupid, others very reasonable.
