>>3792074Having little control is half the goal. Forces you to focus on interesting subjects/compositions and chasing good light and colours, without obsessing over shutter speeds or bokeh or whatever.
Also control on these type of cameras doesn't make much sense anyway. They still use slow, very simple (usually plastic) lenses and take only one kind of film with fixed iso.
You still have basic controls (+-1 EV comp, two aperture settings, flash/no flash, double exposure, bulb). Doubt full aperture control would make a difference.
For manual control to make a decent difference, you'd need a full on medium format camera, at least 6x7 (and this is still smaller than instax square), and this would be a far cry from the ~$100 photo toys current instax cameras are.
The best we can hope for is an instax back for the popular MF cameras for a couple hundred, but even that is not happening it seems.
