The Minox 35GT had a great little lens and a useable light meter, but lacked a rangefinder. I found scale focusing to work in good light, but when the light was marginal and the subject was not at infinity, it got a lot harder. I actually would carry a pocket rangefinder to get a better read on the distance. But it took great shots and there wasn't anything smaller or lighter in 35. Ultimately I replaced it with a Leica CL with its 40mm/2 lens.
