1. Before Purchasing a Camera
What are your plans with the camera? Before you go out and buy a camera, ask yourself this question. Do you want a camera that can capture better photographs than your phone, or do you want to pursue photography as a passion or a business?
What is your financial plan? You may not require a professional-grade Digital SingleReflex Lens (DSLR) camera if you are just getting started, but you may want to purchase something that will allow you to upgrade to a DSLR later. Or maybe you just want something to carry with you so you can take better pictures than your flip phone allows.
Point-and-shoot cameras are ideal for quick snapshots and light travel. They have optical zooms that are unrivaled by cell phones.
Nikon P1000, for example, is a bridge camera. These cameras are a little larger than a point-and-shoot and will have a few extra functions, like superior zoom and telephoto capabilities. They're also a one-piece device, making it simple to maintain the sensor clean and eliminating the need for additional lenses. All except the most expensive professional cameras with multi-thousand-dollar lenses will outperform the Nikon P1000. It's ideal for birdwatching!
DSLR and Mirrorless Cameras with Interchangeable Lenses: These cameras, unlike bridge cameras, allow you to utilize a variety of lenses, giving you more creative possibilities.
Full frame versus medium-format vs APS-C (and micro 4/3): Sensors of various sizes are used in cameras (the digital film). The term "full frame" refers to a sensor that is the same size as a 35mm film negative. APS-C and micro 4/3 cameras feature sensors that are smaller than a 35mm film negative, whereas medium-format cameras have sensors that are bigger. This is important to remember while purchasing lenses and when deciding which camera to purchase. Smaller sensors can have the same number of pixels as full-frame sensors, but the pixels are smaller. Technically, a smaller sensor will not record an image as well as a full frame sensor, although this only applies in extreme cases, such as photographing the Milky Way.
3. Speed and Performance
When purchasing a camera, most people check at the file size, or MegaPixel (MP). The greater the MP, the sharper the image will seem and the larger the print size would be. It also corresponds to the camera's pricing. When purchasing a camera, ISO is an important performance aspect to consider. It basically determines how well your camera performs in low-light settings. You'll require less light if the number is greater. Frames per second (fps) should not be your primary concern unless you want to film athletic events or animals. If you're going to shoot such objects, though, increasing your FPS will enhance your chances of "getting the perfect shot."
4. Mirrorless vs. DSLR
Traditional DSLR cameras feature an internal mirror that lets you to see through the lens and preview the image framing. Mirrorless cameras utilize a sensor to record your picture and send it to the Electronic Viewfinder as a video stream (EVF).
DSLRs are significantly bigger and heavier than compact cameras. Larger cameras feel better in our hands for those of us with large hands. A mirrorless camera is often smaller, lighter, and more convenient to travel with.
Battery life: Mirrorless cameras require smaller batteries (because to the smaller camera body) and have an electronic viewfinder, thus you'll burn through batteries faster. When shooting with a Mirrorless Camera, it's a good idea to have a backup.
Optical vs. Electronic Viewfinder: The optical viewfinder saves battery life, but an electronic viewfinder has the advantage of being able to display you the exposure of your photograph before you take it.
