1. **Sensor size:** The sensor is the heart of any digital camera, and its size has a major impact on image quality. Larger sensors are generally better, as they can capture more light and produce images with less noise.
2. **Resolution:** Resolution refers to the number of pixels in an image. Higher resolution images are larger and contain more detail, but they also require more storage space and processing power.
3. **Lens mount:** The lens mount is the part of the camera that attaches the lens to the body. Different camera brands use different lens mounts, so it's important to make sure that you choose a camera that is compatible with the lenses you want to use.
4. **Viewfinder:** The viewfinder is the small window on the back of the camera that you look through to compose your shots. Viewfinders come in two types: optical and electronic. Optical viewfinders are more traditional and allow you to see the scene through the lens, while electronic viewfinders show you a digital representation of the scene.
5. **Autofocus:** Autofocus is the system that automatically focuses the lens on your subject. There are two main types of autofocus systems: phase detection and contrast detection. Phase detection autofocus is generally faster and more accurate, but it can be more expensive.
6. **Continuous shooting:** Continuous shooting is the ability to take a series of shots in rapid succession. This is useful for capturing fast-moving subjects, such as sports or wildlife.
7. **Video capabilities:** Many SLR cameras also offer video recording capabilities. If you plan on shooting video, it's important to make sure that the camera you choose has the features you need, such as high-definition recording and manual controls.
