What is the best camera for beginners?
There's no single best camera for everyone, but if you want a simple, stylish first camera, I'd start with the Olympus PEN E-PL10. It has a 16.1-megapixel Micro Four Thirds sensor and a flip-down selfie screen. It has no viewfinder, so it's best for shooting at arm's length or on the screen.
The older Olympus PEN E-PL9 uses the same sensor and adds 4K video, so it's worth a look if filming matters to you.
Before you buy, read Your first camera. Every current camera from a major brand is good, so pick the one that feels right in your hand. If you want to save money, buying used is a sensible route.
