What is the difference between a Leica camera and a regular SLR?

Leica is a rangefinder camera, also known as a rangefinder camera. Because the framing optical axis is located next to the optical axis of the photographic lens and is parallel to each other, it is named a "rangefinder" camera. So what's the difference between a Leica camera and a regular SLR?

1. Different brands: Leica's main feature is the production of rangefinder cameras with interchangeable lenses and their high aristocratic value, while ordinary SLRs do not have this high brand support.

2. Different structure: Leica is mainly a rangefinder structure, which is essentially structurally different from an SLR. Most rangefinder cameras are designed with manual focus, and there are not many telephoto lenses. The telephoto lens is not as good as the DSLR, but the rangefinder has the advantage of wide-angle lenses. Obviously, much stronger than SLR.

3. Different photo retouching: Lycra has built-in retouching software, but SLR does not have built-in retouching software, SLR just captures the most original data, which can leave a lot of space for people who like to modify pictures later.
