Using prime (not zoom lenses) tend to aid in 'mental' composition that preceeds the physical composition.

A person who had trained themselves taking (and reviewing) 100s or 1000s of pictures of one particular camera, and one or 2 particular lenses of fixed focal length (prime lenses) -- would have developed a mental model of how a given picture will look, before they take it.

It is that 'pre-physical' mental modeling maturity, that allows experienced photographers to transition to artists (same is for film development and analog printing processes, as well) and stay minimalist at that (as far as gear).

Camera makers are aware of this I think.

This is why cameras with non-detachable, single focal length (prime) lenses are very popular, at any time.

Before it was Yashica Electro 45 [1], now it is Richo GRIII [2] (as examples).

It is also notable that camera makes who make popular SLRs/mirroless cameras such as Nikons, look for current/modern trends of what a 'favorite focal lenght of a lens' is.

For example Nikon recently announced that they will be making 26mm pancake lenth for their Z mirrorless line.

26mm is an 'unusual' focal length, the standard wide-angle is 28mm. And these lenses are usually not pancakes (pancake means very slim / thin lenses that are barely sticking out of the camera body).

But this 26mm focal length is the length (equivalent) of an iphone camera. That's clearly why they are picking this unusual focal length -- and making a optically high quality lens that will fit their full-frame Z range of cameras.

The full frame camera sensor (or even APS-C sized or m4/3 sized sensors) allow to take pictures in low light situations with out flash, while still autofocusing reasonably fast -- much better than with a phone camera.

I would also not be surprised if Nikon would also develop a new Z camera body that will be just big (small) enough to just host these small lenses and that will have perfect integration with phone and pocketable.

So that the camera can utilize this lens, creating much better low-light opportunities without a flash (allowing the photography be more discrete, and take advantage of natural shadows in composition).

They will have to solve battery dimension issues (full frame mirrorless requires more power than a smaller sensor.)

Nikon, I suspect, will also probably enable the post processing to utilize new or (even app-store like) filters to add various effects.

Point I wanted to make is that fixed focal length, single lens, single camera -- enables 'trends', mental-model training and probably other interesting features in the whole word of photography that I do not have words for.

Camera makers certainly know this.

So minimalism in that sense is great, but requires a lot of training and practice :-)
