I have recently seen a lot of cameras that have a large sensor with a fixed lens. Wouldn’t I rather buy a regular mirrorless camera that can change lenses, for cheaper?
The advantage of having a camera that does not change lenses, is that the optics have been designed keeping the sensor in mind. This often means better quality, especially when it comes to fine detail and corner sharpness. And while multiple lens options can be a lifesaver, not everyone needs them. There are photographers who have done a lifetime’s work using just one lens. Henri Cartier-Bresson only used a 50mm, and David Alan Harvey primarily works with a 35mm lens. Simplicity can help you see differently.
