With so many camera brands offering a huge variety of different models at wildly-differing prices, choosing a camera that suits you can be tricky. Like most things though, performance lines up with budget, with the best, most advanced features typically found on more expensive, professional-standard models.
So it's worth spending some time thinking about what you actually need from your camera. If you're looking for something small and light to chuck in a backpack and get some great travel shots then smaller APS-C models like Fujifilm's X-S10 will suit you well and won't break the bank. The OM Systems OM-1 is similarly compact thanks to its smaller image sensor, but its higher price comes with more advanced auto focus, incredible burst firing speeds and pro-standard video options.
If you're looking to take your photography to the next level then look towards full-frame models like the Nikon Z7 II, Sony A7 IV or Canon EOS R5. These cameras all come with higher price tags attached, but their physically larger image sensors allow you to shoot pristine-looking photos that capture more detail in the highlights and shadows of your scene. These are often the cameras you'll see in the hands of professional photographers.
But don't forget, it's not just the camera you're buying, you'll need to consider lenses too. And unfortunately, lenses don't come cheap, with many professional-level lenses costing more than the cameras themselves. Full frame sensors demand bigger lenses to accommodate them, which in turn makes them more expensive, so again, beginners among you will be better served with smaller sensor models from the likes of Fujifilm or Olympus.
