24mm f1.9 is great, but it's not the only special point of this small camera.
When a roll of film with the DX code 1600 or higher is loaded, the camera will be set to NP mode - no auto-flash, +2EV ex-comp, 1/45sec limited slow shutter speed -.
Fuji says that over 40% of photographs are made inside at night with under LV8 or lower - living rooms, restrants, bars or something. Most of those snapshots tend to be unnatural(sometime harsh) with auto-flash. That's what the Natura cameras are designed for.
Most of P&S lowlight snapshots without flash tend to be 2EV under exposed because of top lightings and warm color of modern interior lights(camera meters mainly read green. interior lights tend to lack blue).
Fuji also found that most of average P&S users can hold a camera without significant camera shake in shutter speed of 1/45sec, but not longer. And LV3.5 seems like darkest situation they use a camera.
With a 1600 speed film, +2EV ex-comp, 1/45sec slowest shutter speed and lowest light LV3.5, f1.9 lens was then needed.
Don't judge the Natura cameras only with lens sharpness, AF accuracy or lack of manual controls, but real "AUTO" point and shooting under various situations in daily life(with 1600 film).
There is no auto-everything camera which is like Natura cameras.
Mine is Natura S - lavender color - cute ! 🙂
