I usually don't think of 'landscape' and 'subminiature' at the same time but, thinking about it, I've used a Minolta 16II for landscape type long shots.
That's a 10X14mm negative, even smaller than 110 film format in the Pentax 110 Auto if I recall.
I have so many irons in the fire right now, photographic hobby wise, that I don't know when I'd get back to 16mm. I've toyed with the idea of getting a few rolls of some T-grain B&W in 35mm just to slit down to 16mm. Should be able to get 3 rolls for the Minolta 16 out of a 36 exp. roll.
