Whoo boy, now there’s a question. “What camera should I buy?” or “What is the best camera?” are the two most popular photography questions out there…followed closely by “What camera do you use?” which is just code for “Tell me what you use so I can buy the same thing.”
You’ll get a lot of conflicting answers to these questions. You’ll be told everything from the most expensive offering from *insert famous brand here* to never shoot anything but film if you are serious to full frame sensors are the only cameras that work. Sometimes these bits of advice are well meaning (if often delusional), other times they are handed out with the certainty of a dictator’s edict. Either way, anyone who tells you that so and so camera is the ONLY choice is either delusional or a moron.
The simple truth is that the camera you should buy/the best camera is the one that does what you want it to do. If you only need something for family snapshots there is no reason to spend thousands of dollars on high end gear that will be so complicated you’ll never use it. A decent quality point and shoot is all you need. If you want to shoot sports you need the ability of high quality and fast long lenses. What camera is best all depends on what you want it to do.
That said, the best piece of advice I can tell you when shopping for a camera is to “get thyself to the camera store.” Whether you intend to buy online or not you need to hold the camera in your hands first. See how it feels in your hands. Does the logic behind the menu make sense to you? (Every brand has a different menu logic.) Are the controls easy to work? Getting a camera in your hands is the number one best thing you can do before buying a camera!
