It is an extremely good practice to do the following when considering a camera system purchase:
0) (Preface) Know where you will gain your knowledge. THIS is the single most important part of your entry into photography. Set aside some money for books or classes, and time to learn the basics of technique, technology, and the artistic side of photography — things such as composition, point of view, lighting, contrast, color, moment, purpose, application... THEN consider:
1) Ergonomics — maximize the FEEL of the camera and lenses in your hands (including weight, balance, finger placement, grip, etc.) So RENT or BORROW to try before you buy. One brand may be significantly easier or more difficult for you to handle.
2) Menus — the LAYOUT of the camera menus must make sense. Some brands are FAR more logical than others in the way they organize all the options. So RENT or BORROW to try before you buy. One brand may be significantly easier or more difficult for you to use.
3) What will you photograph? This is critical to know, at least in some detail, so that you get into a system that can handle specific needs. Read reviews at
https://www.dpreview.com and similar sites. Watch camera reviews on YouTube, although know that the people reviewing the cameras are video bloggers who tend to look at the world through THAT "needs filter."
4) Will you record video? This can be irrelevant, or critical, depending upon whether you intend to record BOTH stills and video with the same system. HINT: This is far more important to young people than it is to the primary UHH demographics...
5) What can you spend up front? Digital photography requires a system of components to practice thoroughly. You'll need camera, lenses, tripod, memory cards, card reader, computer, monitor, monitor calibration device (if you print your own or use a lab), printer, inks, papers (if you print your own), software, storage hard drive, backup hard drive, cloud backup service... It can get very expensive!
6) What can you afford later? Add lights, brackets, and stands... more lenses, cases, light modifiers, reflectors, scrims, backdrops, props, and other studio gear if you do studio portraits, product or food photography, architecture, or still life work. Add audio gear (mics, headphones, etc.) for video work.
Know that every camera in the market has been designed to fulfill a certain set of needs — a certain niche. Your job is to find the camera that fits YOUR set of needs, so THINK and research well. What works for one person may be a poor fit for someone else! There is NO perfect camera. There is only the camera that best fits your present needs.
