A 30mm plastic doublet matches the FOV of the 'new' 28mm standard to which casual photographers will be accustomed, but I expect lots of 'bad' selfies with the 1m minimum distance. Fine for viewing as a thumbnail, but probably not an 8x10 candidate.
The DoF quoted in the video of 1m-∞ is achievable @ f/16 with a 2m fixed-focus; f/10 is probably a typo. The utility of a single-use, fixed-focus camera is hugely increased by the inclusion of a helicoid or retractable close-up lens that sets focus at 1m, giving acceptable a DoF from approximately 60cm (arm's length) to 2m.
Exposure is fixed at Ev 13 (1/125s, f16, 400 ISO) which is 'correct' metering outdoors in sunny shade or overcast daylight, without the GNm 32 flash. Using this camera in full sun would seem to prescribe a 2-stop pull in development or reversal processing. Being able to choose a push/pull and developer regime on a postage-paid camera would be pretty nifty.
