Why do you need to use a SLR camera to learn photography?

You don’t necessarily need to use a SLR to learn photography, but if you want to take some more professional photos, ordinary card cameras may not be able to achieve that effect. For example, a simple example: To take photos with shallow depth of field, that is, the effect of blurred background, you need to have a larger aperture, a larger focal length, etc. General card cameras cannot take such effects, as well as the optical zoom factor and shutter speed. The number of gears is not comparable to that of a SLR camera. However, if you are just getting started in photography, it is better to buy a cheaper ordinary consumer camera. After all, the price of a SLR camera is not cheap!
