In the 70s my wife had a either Rolli or a Kodak 126 with 3 lens, she shot mostly color, what ever she found on sale, likely GAF or Kodak, latter I think 3M (Ferraina) after GAF stopped film production. I developed her black and white, Verichrome Pan and some GAF as well. She liked the ease of loading. By the 80s she moved on to a set of 35mm point and shoots. We lived in Sacramento with hot summers, I think the large 126 plastic cassette would warp a bit, some of the images were soft other time very sharp.
I just asked her, she had a Kodak, it had a sort of DX coding and could set the film speed based on the cartridge, don't recall it was only able to set the ASA from Kodak cartridges.
