DSLR Body Type
There are three main types of bodies: entry-level, mid-range or intermediate, and professional. Even the entry-level models will provide high-quality images as photography technology has really advanced over the past few years.
Entry-Level
Entry-level models are good for amateur photographers or those just starting out. User-friendly features make them simple to operate and an auto mode adjusts your settings depending on the lighting conditions to get optimum image quality. Entry-level cameras have interchangeable lenses, and they're a great tool for learning how to use exposure controls like aperture or shutter speed. The factory-installed preset settings help you achieve quality photos. Many models include a guide mode which leads you through the different features for a better understanding of how to work the camera.
Mid-Range
Mid-range, or intermediate, cameras are the next tier. They include an expanded set of manual controls to give you more creative freedom. These also have the ability to record 1080p videos and record audio when you attach a microphone. Mid-range cameras have hot shoes where you can attach an external flash and other accessories. Faster internal processors mean the camera works faster and can take more pictures in a shorter timeframe. The best time to buy a mid-range model is when you have mastered an entry-level model. Many professionals use mid-range cameras as a back up when they're out on a job.
Professional
Professional cameras are the highest quality DSLRs on the market in terms of the build and the features. They give you complete manual control, with image processors that provide excellent image quality. The added memory card slots hold more than one card and give you extra storage, which is a must when you're taking hundreds or thousands of photos in a single session. Professional cameras have interfacing abilities so you can record, add a microphone, and connect to multiple devices. You can shoot raw images and video with professional cameras. There are two main types of cameras in this category: speed/low-light models for outdoor photography and high-res models for commercial purposes like fashion shoots and art photography.
