>>4440883Photographers that care about the art almost always do use medium format or full frame, you're right.
But it's because they actually give a fuck about marginal improvements. It's what they live and breathe for, or make a living off of. So nothing other than the money in their bank account is going to stop them from spending 2x as much for a 20% perceptual improvement if you look very hard.
m43 is good for people who only give a fuck enough for getting 80% of the way there, to get some nice pictures of friends, pets, kids, whatever to put on their fridge. It's good for casuals that want to "get good" but not so good strangers will trust them to take nice photos of their weddings or to get their art into galleries. It's good for people who want an escape of working a day of retail hell and want to have a little fun in the park on a free afternoon with a little side hobby they can't afford to put much money into.
The only casuals it's not good for are autistic fucks who give a shit more about pixel-perfect representation of a wind turbine, than they ever could about a street photo that evokes an emotional response.
